How Is Chronic Kidney Disease Detected

Human Body Systems Functions Overview: The 11 Champions (Updated)

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. 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

    How Do My Kidneys Work

    Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

    How Does The Urinary System Clean My Blood

    Your kidneys are an essential part of filtering your blood. Heres how the urinary system works:

  • Your blood enters each kidney through lots of little arteries.
  • Your kidneys filter your blood, separating toxins from nutrients.
  • Vitamins, minerals, nutrients and proteins return to your bloodstream.
  • Waste products and urine move through your ureters to your bladder. Your bladder stores urine until you use the toilet.
  • Urine leaves your body through your urethra.

    Organ transplantation has been performed by surgeons for more than six decades, and youve no doubt heard of people receiving heart, lung, and kidney transplants. However, you may have never heard of a penis transplant. The first U.S. penis transplant was performed in May 2016 at Massachusetts General Hospital in Boston. The 15-hour procedure involved a team of more than 50 physicians, surgeons, and nurses. The patient was a 64-year-old man who had lost his penis to cancer in 2012. The surgical milestone involved grafting microscopic blood vessels and nerves of the donor organ to those of the recipient. As with most transplant patients, this patient will have to take immunosuppressing drugs for the rest of his life so his immune system will not reject the organ. The transplant team said that their success with this transplant holds promise for patients with devastating genitourinary injuries and disease. They also hope their experiences will be helpful for gender reassignment surgery.

    See the Johns Hopkins Medicine video below for a summary of how the penile and scrotum transplant procedure was carried out:

    Common Diseases Affecting Excretory System Organs

    1. Kidney Stones

    Kidney stones are believed to form from crystals that have separated from urine, forming hard masses in the urinary tract, though the exact cause is unknown. Symptoms for kidney stones include extreme pain, cramping in the lower abdominals and back, nausea, and vomiting. Most kidney stones can be passed by increasing your intake of water to flush them out, although surgery may be needed in some cases.

    2. Urethritis

    Urethritis is a viral or bacterial infection that causes inflammation of the urethra. Symptoms for urethritis vary between the sexes.

    • Symptoms for men include pain or swelling of the penis, blood in urine or semen, frequent urination and pain during ejaculation.
    • Symptoms for females include pain during urination, abdominal pain, fever, chills, frequent urination, vaginal discharge and pelvis pain. Urethritis is usually treated with anti-viral medication, or antibiotics. Painkillers are often used to help sufferers combat the symptoms.

    3. Pyelonephritis

    Pyelonephritis is a type of urinary tract infection that travels from the urethra or bladder and to the kidneys. This infection occurs when bacteria enter the body through the urinary tract. Symptoms include frequent urination, burning during urination, blood in the urine, pain in the groin and abdominal pain. Pyelonephritis is usually treated with oral anti-biotics, although the anti-biotics are sometimes administered intravenously in cases of severe infections.

    4. Cystitis

    How Does Kidney Disease Affect Your Body

    Kidney disease can affect you in a number of different ways. These include:

    Proteinuria or protein in the urine is frequently the earliest symptom of kidney disease. You will have read, in the previous section, how the kidney works and that the kidney has about a million filters. When the kidney is healthy it allows very little protein into the urine. If these filters become leaky, small amounts of protein will leak into the urine. This is frequently an early sign of kidney trouble long before the kidney function itself begins to deteriorate.

    Doctors frequently test patients urine for the presence of blood or protein, to try to detect kidney disease early. There are many causes of protein in the urine, including diabetes and glomerulonephritis. Whilst your doctor will conduct a number of special blood tests, to try to determine the underlying cause, it may be necessary to undergo a kidney biopsy, to establish the exact cause of the protein.

    Patients who have very large amounts of protein in the urine, , are described as having nephrotic syndrome. Patients with nephrotic syndrome frequently have swollen legs.

    Haematuria or blood in the urine can either be present in amounts that you can see or in amounts that you cannot see in which it is only detected with urine testing. Blood in the urine may not appear red but more like strong tea coloured.

    What The Urinary System Does

    Kidney Functions in human body – video for kids

    The principle function of the urinary system is to remove liquid and gaseous wastes from the body. In order to do this, the urinary system performs three main tasks:

    • Excretion: Excretion involves the removal of liquid and gaseous wastes from the blood. Often, dissolved solids are present in the blood and are also removed through excretion.
    • Secretion: Secretion occurs through the production of urine. Once wastes have been removed from the blood, they are released through urine.
    • Elimination: Elimination occurs when urine moves from the bladder to the urethra and then out of the body.

    How Does The Urinary System Work

    The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.

    The body takes nutrients from food and converts them to energy. After the body has taken the food components that it needs, waste products are left behind in the bowel and in the blood.

    The kidney and urinary systems help the body to eliminate liquid waste called urea, and to keep chemicals, such as potassium and sodium, and water in balance. Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the bloodstream to the kidneys, where it is removed along with water and other wastes in the form of urine.

    Other important functions of the kidneys include blood pressure regulation and the production of erythropoietin, which controls red blood cell production in the bone marrow. Kidneys also regulate the acid-base balance and conserve fluids.

    Urinary system diseases: Infographics to understand

    A blood vessel runs alongside the tubule. As the filtered fluid moves along the tubule, the blood vessel reabsorbs almost all of the water, along with minerals and nutrients your body needs. The tubule helps remove excess acid from the blood. The remaining fluid and wastes in the tubule become urine.

    Disorders Of The Human Digestive System

    Vomiting: It is the ejection of stomach contents through the mouth.

    Diarrhoea: It is the abnormal watery bowel movement. Prolonged diarrhoea eventually leads to dehydration.

    Constipation: A condition in which the faeces are clutched within the rectum due to an irregular bowel movement.

    Indigestion: A pain or discomfort in the stomach which is caused when food is not digested properly, resulting in the feeling of fullness. Indigestion is mainly caused due to inadequate enzyme secretion, food poisoning, anxiety, overeating and eating spicy foods.

    Key Differences Between Liver And Kidney

  • The liver is attached to the peritoneum, whereas kidneys lie behind the peritoneum.
  • The liver is a part of the digestive system, whereas the kidney is a part of the excretory system.
  • One pair of kidney and one liver is found in the human body.
  • The liver helps in the metabolism of carbohydrate, proteins and fats, whereas the kidneys help in the excretion of nitrogenous wastes.
  • Glycogen, ions, vitamins etc. are stored in the liver, while the kidney does not perform any storage functions.
  • Therefore, we can conclude that both the liver and kidney are the two essential parts of our body. Without the liver, our digestive system is incomplete, and without a kidney, our excretory system is incomplete. It is evident that in the absence of any organ or cell, the other parts of our body will not function properly. As our body is designed to perform multiple tasks, all the cells and organs perform distinct functions. Therefore, both the liver and kidney are the core of the digestive and the excretory system, respectively.

    Saliva Moistens Food And Begins The Chemical Digestion Process

    Six salivary glands, located around the oral cavity, secrete saliva. This substance moves out of the glands into the oral cavity through ducts. Saliva is 99% water, but also contains enzymes and proteins that lubricate the oral cavity and begin chemical digestion of food. There are three pairs of salivary glands and two ducts on either side of the oral cavity.

    Closing Thoughts: The Body As A Whole

    Structure and Functions of kidney / Kidney / Renal system / Excretory organ / G.L Education

    The human body has 10 major organ systems. Each is highly specialized to perform a specific function. Together they coordinate their functions to form a whole, live, functioning organism.

    In our broader and more complete explanation of fitness, the first major concept is that fitness is a whole body process that requires many interacting systems working in concert. Only when these systems are in harmony can true fitness and maximum performance be attained.

    No one body system functions entirely independently of other systems. Instead, you will find that they are structurally and functionally interrelated and interdependent.

    The Connection Between The Urinary And Digestive Systems

    The reason why the digestive and urinary systems are constantly mentioned together is because of the fact that they work together and complement each other in keeping our body healthy. Our digestive system dissolves food to get valuable nutrients and excretes solid waste, while our urinary system gets rid of the liquid waste.

    Both of these systems have separate organs, but they remain intimately connected by virtue of the processes they both do. As food travels through our intestines, nutrients are absorbed. At the same time, wasteful liquids are also absorbed through the walls of both the small and large intestine and they travel through the circulatory system directly to the urinary system, where they are ultimately led to the urethra and removed from the body.

    What Are The Parts Of The Urinary Tract

    People usually have two kidneys, but can live a normal, healthy life with just one. The kidneys are under the ribcage in the back, one on each side. Each adult kidney is about the size of a fist.

    Each kidney has an outer layer called the cortex, which contains filtering units. The center part of the kidney, the medulla , has fan-shaped structures called pyramids. These drain urine into cup-shaped tubes called calyxes .

    From the calyxes, pee travels out of the kidneys through the ureters to be stored in the bladder . When a person urinates, the pee exits the bladder and goes out of the body through the urethra , another tube-like structure. The male urethra ends at the tip of the penis the female urethra ends just above the vaginal opening.

However, for bodybuilders, weightlifters, professional and recreational athletes, coaches, and regular gym-goers some organ systems are far more more interesting than the others. The major organ systems of athletic performance include: muscular system, skeletal system, nervous system, endocrine system, al well as circulatory and respiratory system. Never forget that as a professional or even recreational bodybuilder you should have at least the basic basic understanding of the anatomy and physiology of the human body.

    The Liver Secretes Bile To Emulsify Fats In The Small Intestine

    Kidney Endocrine Functions

    The liver is one of the largest organs in the body and it is continuously producing bile. This yellowish-brown fluid aids chemical digestion by emulsifying fats in the duodenum. Bile flows out of the liver into the right and left hepatic ducts, into the common hepatic ducts, and toward the small intestine to help with digestion and the absorption of fats.

    Organs In The Excretory System And Their Functions

    The excretory system is essential to ones health. Its responsibility is to remove waste from the body. The excretory system is made up of numerous organs that work in unison to ensure that waste is effectively removed from your body. Below are the details of the organs of excretory system, along with the roles they play in detoxification.

    Male And Female Reproductive Systems

    The reproductive system is the only body system that differs substantially between males and females. Both male and female reproductive systems produce sex-specific sex hormones and gametes . However, the organs involved in these processes are different. The male reproductive system includes the epididymis, testes, and penis. The female reproductive system includes the uterus, ovaries, and mammary glands. The male and female systems also have different additional roles. For example, the male system has the role of delivering gametes to the female reproductive tract, whereas the female system has the roles of supporting an embryo and fetus until birth and also producing milk for the infant after birth.
