Kidneys are one of the important organs in our body. They are present in the rear abdominal cavity on each side of the spine. Receiving almost 20% of the blood from the heart, each kidney converts the waste liquids of the body to urine and then transfers it to the urinary bladder for excretion. Each kidney weighs about 140g and is vital in many different body functions. Thus, to take better care of the kidneys it is necessary for us to understand these functions along with the uses of kidneys, about which we have scarce knowledge.  So, here we are to tell you all that you need to know about the 7 basic functions of the kidney.

Maintaining The Acid-Base Balance In The Body

Maintaining the pH balance or a delicate equilibrium between acid-base in the body is what kidneys primarily do. The normal pH or acid-base balance of the blood is said to be 7.35 to 7.45 which is a neutral value on the pH scale. If the value goes higher than the healthy range then the blood becomes acidic and if it slides down below the healthy range then the blood becomes basic. Kidneys expel any excess acids or bases in the body to maintain a healthy balance and also retain them when needed.

Maintaining The Water Balance

How does your body maintain the right amount of hydration? It is through the help of the kidneys. Kidneys are one of the main organs that assist the body in storing and excreting the right amount of water in the body.

They regulate the amount of urine produced to balance out the water levels and that is why your kidneys produce more urine when you drink more water and less urine when you are dehydrated. 

Keeping A Check On The Blood Pressure

When a person’s blood pressure is low, the kidneys release an enzyme known as renin, which then converts the angiotensinogen(produced in the liver) to angiotensinogen I. After this, when this enzyme reaches the lungs, it gets converted into angiotensinogen II which is known to constrict the blood vessels and raise the blood pressure. 

If a person is suffering from high blood pressure then the kidneys produce and release more urine so that the liquid flow in the body remains controlled, which in turn controls the rise in blood pressure levels.

Controls The Electrolytes

Extracting the electrolytes from the blood, kidneys return the rest of it back into circulation and release the leftover through urine. Thus, they are the body’s primary tools to maintain a controlled presence of electrolytes in the blood.  Sodium and phosphorus are the two main electrolytes that are released or retained by the kidneys.

Releasing The Toxins

Kidneys help in flushing out all the water-soluble waste, toxins, and other unnecessary substances from the body. When your kidneys don’t function properly the toxin build-up causes severe health conditions.

Vitamin D is important for the bones and the regulation of calcium and phosphate. Kidneys convert the calcifediol into calcitriol(an active form of vitamin D) as one of their 7 basic functions.

Now that you know the important kidney functions, and that, they are not just for filtering out the waste but are involved in many different processes in the body. So, you must try to keep your kidneys healthy by maintaining an active schedule, drinking high amounts of fluids, not smoking or consuming alcohol, and eating healthy.
