Kidneys - 5 Functions Performed by this Human Laboratory

Ever wondered what is the structure and functions of those bean-shaped organs that are located near the middle of your back? Kidneys are one of the most vital organs of our body that help keep us healthy and functioning 24X7. Nature gives us two kidneys and they are so important that they cover the possibility if in case one fails to function properly.

Structure of Kidneys

The organs are located right underneath the diaphragm and rib cage. The size of kidney normally ranges in between 8-14 centimeters and also weigh accordingly between 120 grams to 170 grams, depending on person to person. You can say they are each about the size of your first.

Functions of Kidneys

1. A Waste Disposal System

Think of a waste disposal system and we might know the function of this organ. This inbuilt natural filter machine removes excess fluid or wastes such as toxin and converts it into urine which flows through your bladder. 

For this, the kidneys filter out about 190 liters of blood every day to produce 1.9 liters of urine. In short, this trash collector removes extra fluid from your body and keeps you healthy from toxic stuff.

2. Maintains Blood Pressure

Like other machines we see in our daily life, kidneys also need some kind of force or pressure to function properly. For this, kidneys demand blood pressure whether high or low depending on the situation. 

It regulates the blood pressure smartly by controlling fluid levels. Kidneys also produce hormones that help regulate blood flow.

3. Produces Red Blood Cells

Kidneys have another important role and i.e. making a hormone called erythropoietin which instructs the bone marrow to produce red blood cells. 

These red blood cells are responsible for carrying oxygen from your lungs and supply it all through your body. Red blood cells provide you energy for day to day activities.

4. Keeps Bones Healthy

The kidney has an active role in putting the vitamin D to use. The kidney converts vitamin D extracted from ultraviolet radiation and food supplements and convert it to the active form of vitamin D that is useful for our body. 

Our body needs vitamin D to absorb calcium and phosphorus and these minerals make our bones strong.

5. Controls pH levels

pH or potential of hydrogen is a kind of measurement used to determine the acid level in our body. Kidneys are the ones who maintain a healthy balance of chemicals that are used to control acidic levels. 

The food we consume can either increase or decrease the amount of acid in our body depending on the type of food. Kidney smartly adjusts the pH of your body by keeping the right amount of acid.

It will not be an exaggeration to say kidneys are our body’s own laboratories that continue to test things and act accordingly. So, all these things make our kidneys an important player in maintaining our overall health.
