The Role Of Kidneys In The Human Body

Why Do Some Organs Come In Pairs?

Although many people dont think about their kidneys, they are some of the hardest-working organs in the body. The kidneys are responsible for filtering more than 120 quarts of blood every single day. The waste products that are filtered out are quickly eliminated by the body in the form of urine, composed of excess salts, fats, toxins and liquid. ;The ureter is connected to the kidney , and flows down into the bladder, where urine is stored and then eliminated from the body.

Aside from assuring that waste is properly disposed of, kidneys are also critical to the balance of electrolytes in our body. Minerals like sodium, potassium and calcium, among others, help to maintain water balance in the system, as well as optimize nervous system communication. Without the kidneys functioning, or present, the body would not be able to function. The composition of our blood must remain stable, if we are to remain healthy, and the kidneys guarantee that happens.

Furthermore, kidneys produce key hormones that the body requires, such as hormones for strengthening bones, creating new red blood cells and maintaining blood pressure. Clearly, while the kidneys are often overlooked behind major organs like the brain, heart and lungs, they are just as critical to our survival.

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.

Can Dialysis Keep You Alive If Your Kidney Are Removed

There are two types of dialysis peritoneal dialysis and hemodialysis. In the former, your blood is actually cleaned inside the body, by injecting a fluid into the abdominal cavity that will absorb waste products in the blood. This liquid can then be removed, along with the toxins. The more intensive and common form is hemodialysis, in which the blood is removed from the body, filtered, and then returned to the body. This process can take hours to complete, and must be done 2-3 times per week.

Depending on the intricacies of your hemodialysis treatment, you may be able to perform it at home, but this often requires more frequent filtering.;Essentially, it is possible to live without your kidneys, but the need for dialysis is a life-changing medical condition that you will need for the rest of your life. Dialysis can often be used for years or decades, and is the only option for many people who are waiting for a healthy kidney. While some people do eventually get a kidney through donor programs, the lists are quite long, with thousands;of people waiting for a life-saving;organ.

Myth: Dialysis Is The Treatment For Kidney Disease

FACT: Dialysis is a method of purification of blood of waste products which are not removed because of kidney failure. Dialysis in fact does not do anything for kidney disease. Dialysis is only required when kidney function decreases to less than 15 ml/min and patients cannot sustain life meaningfully. In earlier stages of chronic kidney disease, one slows down the rate of progression of kidney disease to delay or avoid the need for dialysis or kidney transplantation.

What If I Was Born With Only One Working Kidney

Why do you have two kidneys if you only need one?

In general, most people with a single, healthy kidney have few problems. However, some long term problems have been seen in some people.

In some people who were born with a single kidney, or had a kidney removed during childhood, there is a chance of some slight loss in kidney function later in life. This usually takes 25 years or more to happen. There may also be a chance of having high blood pressure later in life. However, the loss in kidney function is usually very mild, and life span is normal. Most people with one kidney live healthy, normal lives with few problems.

In other words, one healthy kidney can work as well as two.

Facts About Kidney Health

Kidneys are one of the most vital organs in the body which excrete the toxic waste products formed as a result of metabolism in the body.

Signs You May Have Kidney Disease

More than 37 million American adults are living with kidney disease and most dont know it. There are a number of physical signs of kidney disease, but sometimes people attribute them to other conditions. Also, those with kidney disease tend not to experience symptoms until the very late stages, when the kidneys are failing or when there are large amounts of protein in the urine. This is one of the reasons why only 10% of people with chronic kidney disease know that they have it, says Dr. Joseph Vassalotti, Chief Medical Officer at the National Kidney Foundation.

While the only way to know for sure if you have kidney disease is to get tested, Dr. Vassalotti shares 10 possible signs you may have kidney disease.

What About A Kidney Transplant

According to the National Institute of Diabetes and Digestive and Kidney Health, almost 200,000 people in the United States have a functioning transplanted kidney.

A kidney transplant is only done when you have no functioning kidneys. The risks of the procedure and side effects of the medications youll need for the rest of your life outweigh the small increase in function you get from a second kidney.

If your solitary kidney gets injured or sick and stops working, you might be eligible for a transplant.

No matter how many kidneys you started with, you only receive one kidney in a transplant. The transplanted kidney usually gets bigger and works harder over time. Eventually, your transplanted kidney will function almost as well as two kidneys.

Stage 2 CKD is largely asymptomatic, with most noticeable symptoms not appearing until your condition has progressed to stage 3.

Possible symptoms include:

How to Eat Right for Your Kidneys?

High blood pressure can damage blood vessels in your solitary kidney. If your kidneys blood vessels are damaged, they may no longer work properly. When this happens, the kidney is not able to remove all wastes and extra fluid from your body. Extra fluid in the blood vessels can raise your blood pressure even more, creating a dangerous cycle, and cause more damage leading to kidney failure.

If your health care professional diagnoses you with high blood pressure, he or she may prescribe one or more blood pressure-lowering medicines. Medicines that lower blood pressure can also significantly slow the progression of kidney disease.

Two types of blood pressure-lowering medicines, angiotensin-converting enzyme inhibitors;and angiotensin receptor blockers , may be effective in slowing your kidney disease progression while also lowering your blood pressure. A health care professional may also prescribe a diuretic.

Can You Drink Alcohol With Only One Kidney

Many of your bodys organs are affected by alcohol including your kidneys. Drinking in moderation usually wont harm your kidneys.

Alcohol increases the amount of urine you produce but reduces your kidneys ability to filter blood. This disrupts the fluid and electrolyte balance in your body, and you become dehydrated.

Without enough fluid in your body, the cells in your organs, including your kidneys, cant function properly. Eventually it may cause permanent damage.

Your liver is also important for maintaining fluid and electrolyte balance. Liver damage from excessive alcohol interferes with this balance, making it even harder for your kidneys to work correctly.

The risk of kidney damage is even higher for heavy drinkers who also smoke.

Alcohol has this effect whether you have one or two kidneys, but it may lead to kidney failure more quickly when you only have one functioning kidney.

How Your Kidneys Work

Your kidneys play a vital role in your body. They work hard to clean your blood and create urine for you 24 hours a day. Without kidney function, you would struggle to process toxins and eliminate waste, and this would have a devastating impact on your health.

Its important to keep your kidneys healthy so they can perform these important tasks throughout your life. If your kidneys are not healthy, other organs in your body may suffer and this could lead to further health complications.

Why Do We Have Two Kidneys

This piece is part of the The Conversation’s Curious Kids series for children.

Why do we have two kidneys when we can live with only one? Question from the students of Ms Morris Grade 5 class, Ringwood North Primary School, Victoria.

This is a really great question. The answer is scientists are not completely sure but we do have some theories. That is often the case with science.

Most of the animals you see above ground on Earth today, including humans, are the same on both sides. We have two eyes, two ears, and even two nostrils. Scientists gave this a fancy name called bilateral symmetry.

If you look in the mirror and draw an imaginary line down the middle of your reflection you will see that you have an arm and a leg on each side. If you had goggles that let you see your insides, you would see that you also have a kidney and a lung on each side too.

But it wasnt always like this. And some;animals still only have one kidney.

Around 500 million years ago, our long-lost relatives that were living in the ocean decided to leave the water to walk and live on land.

This was a very important moment in our history because on land, animals could change to grow a very complicated body with all of the important organs that are inside you, including two kidneys.

Myth: If You Have Kidney Disease You Will Know It

FACT: Common symptoms of kidney disease include swelling of the eyes and feet, frothy urine or blood in the urine. However, most kidney diseases do not show symptoms in the early stages.
