Kidneys are vital organs of our body. They act as cleaners, as they purify our blood and keeps it chemically balanced.Part of the urinary system, the kidneys filter wastes (especially urea) from the blood and excrete them, along with water, as urine.
In humans, the kidneys are located in the earlier part of the abdomen. There is one on each side of the spine; the right kidney sits just below the liver, the left below the diaphragm and adjacent to the spleen. So, to understand our kidneys better, we are here with a lot of useful information, functions and facts about kidneys.
· The Kidneys absorb and distribute 99.9% of the blood volume. Only 0.1% of the blood filtered turns into urine.
· Inside each kidney are right around a million nephrons. These are tiny filters that catch all of the stuff going through blood. All of the waste from blood goes out into urine.
· The Kidneys filter almost 200 quarts of blood every day.
· Each Kidney is about 5 inches long (13 centimeters) and weighs approximately 4 to 6 ounces (120-140 grams).
· Kidneys keep a balance of acids and bases ratio in the body.
· Kidneys simulate the production of red blood cells in the body by releasing a hormone erythropoietin.
· Heart disease is very common among people with Chronic Kidney Disease. CKD patients are more likely than the general population to develop heart condition. That’s why following all the necessary steps to prevent heart problems is absolutely crucial. What they should do is eat healthy foods, exercise on a regular basis and kick a smoking habit (in case they smoke). CKD patients should cut down on foods that contain saturated fat, such as eggs, milk, cheese and fried foods. Healthy foods rich in omega-3 fatty acids should become a part of their dietary regime.
· The kidneys keep the amount of fluid constant in your body. Adults have around 7-8 liters of blood, and this is constantly filtered by the kidneys, as much as 400 times per day! If someone is dehydrated (not drinking enough water), the kidneys will not make much urine until the person starts drinking again and their blood volume goes up.
· The kidneys also sense the amount of oxygen in the blood. If they aren't getting enough oxygen, they will make a hormone that sends a signal to your body to make more red blood cells, which are the cells in blood that carry oxygen.
· Kidney failure is not always permanent, which is great news for many people. In some cases of acute kidney failure, the kidney function returns with conservative management. Unfortunately, most causes of kidney disease are more insidious. They can progress slowly but steadily and without the proper management can lead to end stage kidney disease, requiring renal replacement therapy.
· Patients with kidney dysfunction commonly develop anemia as a result of decreased hormone production in kidneys. Anemia can result in fatigue and a diminished functional status. Those with CKD and anemia can be treated effectively with medication.
· The kidneys of a newborn baby are about 3X larger in proportion to body weight as in the adult.
· The volume of urine excreted daily varies from 1000 to 2000 ml (averaging 1500 ml). 1000 ml (milliliters) = 1 liter.
· The kidneys have a higher blood flow than even the brain, liver or heart.
