How Is Chronic Kidney Disease Detected

Kidney Functions in human body – video for kids

Early detection and treatment of chronic kidney disease are the keys to keeping kidney disease from progressing to kidney failure. Some simple tests can be done to detect early kidney disease. They are:

  • A test for protein in the urine. Albumin to Creatinine Ratio , estimates the amount of a albumin that is in your urine.Â;An excess amount of protein in your urine may mean your kidney’s filtering units have been damaged by disease. One positive result could be due to fever or heavy exercise, so your doctor will want to confirm your test over several weeks.
  • A test for blood creatinine. Your doctor should use your results, along with your age, race, gender and other factors, to calculate your glomerular filtration rate . Your GFR tells how much kidney function you have. To access the GFR calculator, .
  • It is especially important that people who have an increased risk for chronic kidney disease have these tests. You may have an increased risk for kidney disease if you:

    • are older

    What Could Go Wrong With The Kidneys

    When the kidneys are not working correctly, waste products and excess fluid can build up and the levels of sodium, potassium, phosphate and calcium are not regulated correctly. When these substances gather together, this causes the symptoms of kidney disease, which can include high blood pressure, excessive tiredness, fluid retention and possibly lower back pain.

    Kidney damage can occur for a number of reasons diabetes, high blood pressure, infections and a group of diseases that affect the glomerulus.;The kidneys also need an adequate supply of blood, so if there is something wrong with the blood vessels to the kidney, such as a narrowing, this will prevent the kidneys from working efficiently.;

    What Do The Kidneys Do

    The kidneys have a number of roles in the body;

    • The kidneys ensure that the make-up and volume of the fluids in the body is correct.;
    • They help control the chemical balance of the blood and regulate the body’s level of;sodium,;potassium;and calcium.;
    • The kidneys remove waste products and excess water from the body and so help to regulate blood pressure.
    • They activate;vitamin D, which helps to maintain strong bones.
    • They produce;erythropoietin, a hormone that is vital for the production of red blood cells.

    Functional Structure Of The Kidneys


    1. The tubule begins with a hollow enlargement called Bowman’s capsule, which is where water and solutes initially enter the tubule from the bloodstream. This process is known as filtration. The structure comprised of Bowman’s capsule and associated capillaries is called the renal corpuscle.

    2. From Bowman’s capsule the tubular fluid flows towards the proximal tubule, which remains in the outer layer of the kidney. The proximal tubule is the major site of reabsorption of water and solutes in equal proportions from the filtered tubular fluid.

    3. Then the tubule dips into the hairpin loop of Henle, which descends toward the center of the kidney and then rises back to the cortex. The loop of Henle is also a major site of reabsorption, but unlike the proximal tubule, proportionately more solute than water is reabsorbed, so the tubular fluid is dilute relative to plasma by the end of this segment.

    4. The next segment is the distal tubule, which like the proximal tubule remains in the cortex. Both reabsorption and secretion take place in this segment, which is where sodium and potassium concentrations and the pH of the tubular fluid are adjusted to ensure homeostasis.

    1. An afferent arteriole takes blood to the renal corpuscle, where the blood passes through the first capillary bed, a ball-shape tuft known as the glomerulus.

    2. An efferent arteriole takes blood away from the glomerulus.

    Four Key Concepts And Talking Points

    Water Homeostasis

    1. Talk to patients about their kidneys, CKD, and their risk.

    What is CKD? CKD means the kidneys are damaged and may no longer filter blood well. This damage happens over many years. As more damage occurs, the kidneys are unable to keep the body healthy – then dialysis or a kidney transplant may be needed to maintain health.

    How can I lower my risk for CKD? The steps you take to manage your diabetes and high blood pressure also help protect your kidneys. Choosing healthy foods, quitting smoking, and being more physically active are all important steps.

    2. Communicate the importance of testing and how CKD is diagnosed.

    What are the symptoms of CKD? Most people with CKD have no symptoms until their kidneys are about to fail. The only way to know if you have kidney disease is to get tested. The sooner kidney disease is found, the sooner you can take steps to begin treatment and keep your kidneys healthier longer.

    How do you check for CKD? A blood test and a urine test are used to find kidney disease. Because you are at risk, you should get these tests regularly:

    • GFR – A blood test measures how much blood your kidneys filter each minute, which is known as your glomerular filtration rate .
    • Urine Albumin – A urine test checks for albumin in your urine. Albumin is a protein that can pass into the urine when the filters in the kidneys are damaged.

    3. Explain the progressive nature of CKD and the basics of treatment.

    4. Begin to speak about dialysis and transplantation.

    What Color Is Urine When Your Kidneys Are Failing

    When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple. The color change is due to abnormal protein or sugar, high levels of red and white blood cells, and high numbers of tube-shaped particles called cellular casts.

    Kidneys Are A Filter System

    The main job of the kidneys is to remove waste from the blood and return the cleaned blood back to the body. Each minute about one litre of blood one-fifth of all the blood pumped by the heart enters the kidneys through the renal arteries. After the blood is cleaned, it flows back into the body through the renal veins.

    Each kidney contains about one million tiny units called nephrons. Each nephron is made up of a very small filter, called a glomerulus, which is attached to a tubule. As blood passes through the nephron, fluid and waste products are filtered out. Much of the fluid is then returned to the blood, while the waste products are concentrated in any extra fluid as urine .

    The urine flows through a tube called the ureter into the bladder. Urine passes from the bladder out of the body through a tube called the urethra. The kidney usually makes one to two litres of urine every day depending on your build, how much you drink, the temperature and the amount of exercise you do.

    A healthy kidney can greatly increase its work capacity. With two healthy kidneys, each kidney performs 50 per cent of the normal kidney function. If one kidney is lost, the other kidney can enlarge and provide up to 75 per cent of the normal kidney function .;;

    Why Are The Kidneys So Important

    Most people know that a major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine. The production of urine involves highly complex steps of excretion and re-absorption. This process is necessary to maintain a stable balance of body chemicals.

    The critical regulation of the body’s salt, potassium and acid content is performed by the kidneys. The kidneys also produce hormones that affect the function of other organs. For example, a hormone produced by the kidneys stimulates red blood cell production. Other hormones produced by the kidneys help regulate blood pressure and control calcium metabolism.

    The kidneys are powerful chemical factories that perform the following functions:

    • remove waste products from the body
    • remove drugs from the body
    • balance the body’s fluids
    • release hormones that regulate blood pressure
    • produce an active form of vitamin D that promotes strong, healthy bones
    • control the production of red blood cells

    Below you will find more information about the kidneys and the vital role they play in keeping your body functioning.

    Kidney Anatomy: Parts Function And Characteristics

    Kidney Function Tests, Animation

    In this article, we are going to analyze the kidney anatomy and the different functions of each of its parts . The kidney is one of the primary organs of the human body and the urinary system, its evolution until today has been indispensable for the survival of all species.

    Performing essential functions with unique characteristics, in comparison with other organs, it is one of the fundamental elements for the body’s homeostasis and survival.

    What Is The Functional And Structural Unit Of A Kidney

    The structural and functional unit of the kidney is called nephron. It consists of two main parts viz. the glomerulus and the tubular system. The glomerulus is composed of Bowmans capsule and a tuft of leaky blood vessels encapsulated by the Bowmans capsule. The primary purpose of the glomerulus is filtration. The leaky vessels filter into the glomerulus almost all the water, electrolytes, small proteins, nutrients such as sugar etc and excretory products such as urea etc. The filtration are dependent on the size and charge of the particles. The average pore size is 8 mm and hence particles of only smaller size will pass through. Also, the basement membrane carries a negative charge, hence preventing negatively charged particles from passing through. The tubular system is responsible for reabsorption of most of the water, electrolytes, nutrients as well as excretion of the remaining nutrients by means of secretion into the tubules. These tubules are responsible for the concentration of urine.

    Promoting Good Kidney Health

    Proper care can keep kidneys running properly well into old age. One of the most important things to remember is to stay hydrated. Kidneys need water to function properly and to carry away toxins.;

    In the most serious cases, dehydration can eventually harm the body causing seizures, kidney failure and even death, said;Dr.;Buck;Parker, a trauma surgeon who also recently appeared on NBCs reality TV show The Island. Parker suggested that the best ways to avoid dehydration included drinking water before you get thirsty, since thirst indicates dehydration; eating foods, like fruits and vegetables, with a high water content; avoiding soda or other caffeinated drinks; and limiting alcohol consumption.

    Vitamins can be very important to the function and health of kidneys. helps to reduce levels of homocysteine, which has been linked to heart disease, stroke and kidney disease, said Dr. Kristine Arthur, an internist at Orange Coast Memorial Medical Center in Fountain Valley, California. Vitamin A is also very important to healthy kidney function.;

    Taking too much vitamin C, though, may lead to kidney stones, according to Arthur.

    Keeping blood pressure in check may also contribute to long-term good kidney health. A study by the;National Kidney Foundation;found that moderately high blood pressure levels in midlife might contribute to late-life kidney disease and kidney failure.

    What Are Some Of The Causes Of Chronic Kidney Disease

    Chronic kidney disease is defined as having some type of kidney abnormality, or “marker”, such as protein in the urine and having decreased kidney function for three months or longer.

    There are many causes of chronic kidney disease. The kidneys may be affected by diseases such as diabetes and high blood pressure. Some kidney conditions are inherited .

    Others are congenital; that is, individuals may be born with an abnormality that can affect their kidneys. The following are some of the most common types and causes of kidney damage.

    Diabetes is a disease in which your body does not make enough insulin or cannot use normal amounts of insulin properly. This results in a high blood sugar level, which can cause problems in many parts of your body. Diabetes is the leading cause of kidney disease.

    High blood pressure is another common cause of kidney disease and other complications such as heart attacks and strokes. High blood pressure occurs when the force of blood against your artery walls increases. When high blood pressure is controlled, the risk of complications such as chronic kidney disease is decreased.

    Glomerulonephritis is a disease that causes inflammation of the kidney’s tiny filtering units called the glomeruli. Glomerulonephritis may happen suddenly, for example, after a strep throat, and the individual may get well again.However, the disease may develop slowly over several years and it may cause progressive loss of kidney function.

    Hypertension And Kidney Health

    Urinary System for Kids

    Hypertension which is another name for high blood pressure is the No. 2 cause of chronic kidney disease in the United States. In fact, 80 percent to 85 percent of people with chronic kidney disease have hypertension.

    Chronic kidney disease can cause hypertension; likewise, hypertension can cause chronic kidney disease. Regardless of which came first, its vital to have blood pressure well-controlled and to take medications that help off-load pressure on the kidney.

    State Two Vital Functions Of Human Kidney

    Tow vital function of human kidney:

  • Kidneys are the primary organs that are responsible for osmoregulation in human body. Osmoregulation is the process of maintaining and circulating proper water levels in the body and it also involves in removing the metabolic wastes from the blood.
  • It mainly supports excretion, so a defect that occurs in kidney will leads to improper excretory function. It also circulates mineral ions in the body fluids and keeps it in perfect condition.
  • Absorption of water and salt

    Removal of waste materials like urea, ammonia etc from blood.

    Artificial kidney works on the principal of dialysis. It is also known as haemodialysis.

    In hemodialysis, only a few drops of blood are allowed to flow, through a special filter that removes wastes and extra fluid. The detoxified blood is then returned to the body.

    The special filter used in dialysis consists of a number of tubes with semi-permeable lining, suspended in a tank filled with the dialysis fluid.

    Function Of The Kidney

    The primary function of the kidney is to continuously remove nitrogenous wastes from the body.; This, however, is not its only function.; It performs a number of other crucial functions, making it one of the most versatile organs of the body.;

    In this article, we outline eight key functions performed by the kidneys.

    1. Primary Function: Removing Wastes Products from the Blood

    Filtering blood is the primary function of the kidney.; This process is handled by the;urinary excretory system, of which the kidneys are the main organs. Every day the kidneys process about 200 quarts of blood and filters out about 2 quarts of waste products and extra water.;

    Waste is any substance that is not useful to the body. This could be any substance or chemical that the body cannot use at all, or even if the body can use it, if it is present in excess of what the body needs then the excess is classified as waste. If wastes are allowed to accumulate in the body, the results can be deadly. It is, therefore, crucial for wastes to be eliminated from the body, relatively quickly.

    2. Urine Formation – Another Vital Function of the Kidney

    Once the kidneys have filtered the blood and removed the waste products from it, the next step is to get rid of the wastes from the body. Urine formation is the process by which the kidneys prepare waste products, filtered from the blood, for elimination from the body.

    3. Regulating the body’s water volume

    4. The Kidneys Regulate The Body’s Salt Content

    What Are The Two Primary Functions Of The Kidneys

    Basic Renal Function: The Basics

    The kidneys perform many crucial functions, including:

    • maintaining overall fluid balance.
    • regulating and filtering minerals from blood.
    • filtering waste materials from food, medications, and toxic substances.
    • creating hormones that help produce red blood cells, promote bone health, and regulate blood pressure.

    The kidneys perform the essential function of removing waste products from the blood and regulating the water fluid levels. The diagram below shows the basic structure of the kidney. The kidneys receive blood through the renal artery.

    Secondly, what are the two main parts of the nephron? Answer: The Renal Corpuscle, which is its filtering component, and the Renal Tubule, where waste is processed and carried away. The Corpuscle is the entrance and filtering point of the Nephron and the Tubule is the processing and exiting point of the Nephron.

    In respect to this, what is the main function of the kidneys quizlet?

    Function – extract waste from blood, balance body fluids, form urine, and aid in other important functions of the body. Location – They are located just below the rib cage, one on each side of the spine.
