What Is Normal Kidney Function

How do your kidneys work? – Emma Bryce

Since many of those living with kidney disease dont experience signs or symptoms until the disease has progressed, understanding normal kidney function is vital to understanding your kidney health.

From the filtering of waste products to the water balance in the body – the kidneys perform many crucial functions. Some of the kidneys key functions include:

Can Kidney Failure Be Prevented

While kidney failure from chronic kidney disease cant be reversed, you can do many things to help preserve the kidney function you have today. Healthy habits and routines may slow down how quickly kidneys lose their functional abilities.

If you have chronic kidney disease or kidney failure, youll want to:

  • Monitor your kidney function, with your doctors help.
  • Keep your blood sugar levels under control, if you have diabetes.
  • Keep your blood pressure levels in a normal range.
  • Avoid smoking.
  • Make healthy diet choices, such as limiting foods high in protein and sodium.

What Are The Symptoms Of Kidney Problems

Most kidney problems dont have symptoms in the early stages. As kidney damage progresses, you may notice:

  • Cramping muscles: Electrolyte imbalances cause your muscles to stiffen.
  • Dark urine or urine with blood in it: Damage to the kidneys filters lets blood cells leak into your urine.
  • Foamy urine: Bubbles in your pee can signal excess protein.
  • Itchy, dry skin: An imbalance of minerals and nutrients in your blood leads to itchy skin.
  • More frequent urination: Problems filtering waste cause you to pee more often.
  • Puffy eyes or swollen ankles and feet: Reduced kidney function can cause your body to hold onto protein and sodium, leading to edema .
  • Sleep problems, fatigue and lack of appetite: If toxins build up in your blood, your sleep, appetite and energy levels may be off.

What Should My Gfr Be For My Age

If the glomerular filtration rate is low, it may indicate that the kidneys are not working as they should.

According to the National Kidney Foundation, a normal glomerular filtration rate in adults is above 90, though this ‘normal’ rate may differ based on age.

  • 20-29 years: 116
  • 60-69 years: 85
  • 70+ years: 75

It’s important to note that a low GFR may indicate kidney disease but early detection and treatment may help the kidney disease worsening.

How Do The Kidneys Filter The Blood

How do kidney cells excrete their own wastes?

Each kidney contains more than a million filtering units called nephrons. Each nephron consists of:

  • Glomeruli: These groups of tiny blood vessels perform the first stage of filtering your blood. They then pass filtered substances to the renal tubules. The process is called glomerular filtration.
  • Renal tubules: These tiny tubes keep water, nutrients and minerals your body needs . The tubules remove waste, such as excess acid and fluids. Your body sends the remaining waste through the kidneys collecting chambers. Eventually, it leaves your body as urine.

The kidneys are two bean-shaped organs that extract waste from blood, balance body fluids, form urine, and aid in other important functions of the body.

They reside against the back muscles in the upper abdominal cavity. They sit opposite each other on either side of the spine. The right kidney sits a little bit lower than the left to accommodate the liver.

When it comes to components of the urinary system, the kidneys are multi-functional powerhouses of activity. Some of the core actions of the kidneys include:

Most people are born with two kidneys, but many people can live on just one. Kidney transplant surgeries with live donors are common medical procedures today.

Because of all of the vital functions the kidneys perform and the toxins they encounter, the kidneys are susceptible to various problems.

Acute kidney failure is a condition in which the kidneys suddenly lose their ability to function properly. This can occur for many reasons, including:

  • Infection
  • Autoimmune kidney disorders

Should You Check Your Kidney Function

If youre concerned about symptoms that youre experiencing, its important to make a trip to your doctor for a check-up.

What Is The Function Of Our Kidneys

The kidneys are a very important organ in the body. They are two bean-shaped organs, each about the size of a fist, located just below the rib cage, one on each side of your spine. The kidneys are responsible for getting rid of waste products, drugs, and toxins through our urine.

Your kidneys also:

  • Regulate amount of fluid within the body
  • Help regulate blood pressure
  • Produce hormones that affect blood and bones
  • A kidney is composed of tiny units called nephrons
  • Nephrons consist of glomeruli and tubules
  • Glomeruli are small blood vessels that filter wastes and excess fluids
  • Tubules collect the waste to form urine

Other Functions Of Kidneys

Despite their small size each kidney is only about the size of your fist your kidneys perform a variety of essential functions. Most notably, kidneys remove dangerous toxins and excess water from your blood and eliminate them through your urine. Kidneys also perform other amazing physiological feats, from regulating the amount of fluid in your body to controlling the salt content of that fluid. Here are three more amazing kidney functions.

A Patient With A Diagnosis Of Respiratory Acidosis Is Experiencing Renal Compensation What Function Does The Kidney Perform To Assist In Restoring Acidbase Balance

A) Sequestering free hydrogen ions in the nephronsB) Returning bicarbonate to the bodys circulationC) Returning acid to the bodys circulationD) Excreting bicarbonate in the urine

Answer:BFeedback:The kidney performs two major functions to assist in acidbase balance. The first is to reabsorb and return to the bodys circulation any bicarbonate from the urinary filtrate the second is to excrete acid in the urine. Retaining bicarbonate will counteract an acidotic state. The nephrons do not sequester free hydrogen ions.

How Does Blood Flow Through My Kidneys

Blood flows into your kidney through the renalartery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.

Your blood circulates through your kidneys many times a day. In a single day, your kidneys filter about 150 quarts of blood. Most of the water and other substances that filter through your glomeruli are returned to your blood by the tubules. Only 1 to 2 quarts become urine.

Four Key Concepts And Talking Points

How Kidneys Work

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 Is Kidney Failure

Kidney failure means one or both kidneys can no longer function well on their own. Sometimes, kidney failure is temporary and comes on quickly. Other times, it is a chronic condition that can get worse slowly over a long time.

Kidney failure may sound serious, and it is. But treatments such as dialysis and kidney transplant help many people with limited kidney function continue to live fulfilling lives.

Can You Live Without Your Kidneys

You do need a kidney to survive, but you can live with just one kidney. Having one kidney removed is called a radical nephrectomy.

Someone may have only one kidney if they:

  • Had a kidney removed due to cancer or injury.
  • Made a kidney donation to someone else for a kidney transplant.
  • Were born with only one kidney .
  • Were born with two kidneys but only one kidney works .

Kidney Structures And Functions Explained

Your kidneys are paired organs found on each side of the back portion of the abdominal cavity. The larger left kidney is located a bit higher than the right kidney. Unlike other organs found in the abdomen, the kidneys are located behind the lining of the abdominal cavity, thus they are considered retroperitoneal organs. These bean-shaped organs are protected by the back muscles and the ribs, as well as the fat that surrounds them like a protective padding.

What Causes Kidney Failure

The most common causes of kidney failure are diabetes and high blood pressure. Sometimes, though, kidney failure happens quickly due to an unforeseen cause.

When the kidneys lose function suddenly , its called acute kidney failure . This type of kidney failure is often temporary. Common causes of acute kidney failure can include:

  • Autoimmune kidney diseases
  • A urinary tract obstruction
  • Uncontrolled systemic disease like heart or liver disease

Kidney failure usually doesnt happen overnight. Chronic kidney disease refers to a group of health conditions that affect how well your kidneys function over time. If left untreated, chronic kidney disease can lead to kidney failure.

The biggest causes of kidney failure from chronic kidney disease are:

  • Diabetes: Unmanaged diabetes can lead to uncontrolled blood sugar levels. Consistently high blood sugar can damage the bodys organs, including the kidneys.
  • High blood pressure: High blood pressure means blood travels through your bodys blood vessels with increased force. Over time, untreated high blood pressure levels can damage the kidneys tissue.

Other causes of chronic kidney disease include:

  • Polycystic kidney disease, a hereditary condition where cysts grow inside your kidneys.
  • Glomerular diseases, such as glomerulonephritis, which affect how well the kidneys can filter waste.
  • Lupus and other autoimmune diseases that can affect multiple body systems.

What Do Kidneys Do

Water Homeostasis

One of the main jobs of the kidneys is to filter the waste out of the blood. How does the waste get in your blood? Well, your blood delivers nutrients to your body. Chemical reactions in the cells of your body break down the nutrients. Some of the waste is the result of these chemical reactions. Some is just stuff your body doesn’t need because it already has enough. The waste has to go somewhere this is where the kidneys come in.

First, blood is carried into the kidneys by the renal artery . The average person has 1 to 1½ gallons of blood circulating through his or her body. The kidneys filter that blood about 40 times a day! More than 1 million tiny filters inside the kidneys remove the waste. These filters, called nephrons , are so small you can see them only with a high-powered microscope.

The 7 Functions Of The Kidneys

Most people know that the primary function of the kidneys is to eliminate waste products from the body by flushing them out with urine. However, did you know that there are at least 6 other fabulous functions you should thank your kidneys for?

Shaheen Motiwala, MD is one of our nephrologist at Florida Kidney Physicians who loves to educate patients. Here is a brief overview of the 7 primary functions of the kidneys to help patients become more familiar with how these amazing organs work.

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.

Where Are The Kidneys And How Do They Function

There are two kidneys, each about the size of a fist, located on either side of the spine at the lowest level of the rib cage. Each kidney contains up to a million functioning units called nephrons. A nephron consists of a filtering unit of tiny blood vessels called a glomerulus attached to a tubule. When blood enters the glomerulus, it is filtered and the remaining fluid then passes along the tubule. In the tubule, chemicals and water are either added to or removed from this filtered fluid according to the body’s needs, the final product being the urine we excrete.

The kidneys perform their life-sustaining job of filtering and returning to the bloodstream about 200 quarts of fluid every 24 hours. About two quarts are removed from the body in the form of urine, and about 198 quarts are recovered. The urine we excrete has been stored in the bladder for anywhere from 1 to 8 hours.
