The human body relies on several internal organs to survive and reproduce. Each organ has an associated function with the other to maintain life. The brain, the lungs, the liver, the bladder, the kidneys, the heart, the stomach and the intestines perform their respective functions in the body.

Kidneys perform their respective functions on a daily basis to maintain a chemical balance in the body. The human body needs to maintain a chemical balance for the prevention of chronic illness and other abnormalities that may affect other organs.


Concomitant to their name, kidneys are positioned at the back of the abdominal cavity. Kidneys execute some very vital functions in the human body. These entail formation of urine, balancing chemicals and fluids in the body and extracting waste from the bloodstream. Moreover, they assist various other organs in carrying out routine functions in the body.

The pre-eminent functions of the kidneys are as follows

1. Blood Pressure Regulation

Kidneys require a consistent flow of blood to filter it. In case the blood pressure drops, kidneys immediately begin increasing it. This is attained by the production of a vessel-constricting protein known as angiotensin. The kidneys produce this protein to regulate blood pressure and signal the body to retain water and sodium.

2. Waste Excretion

The human body accumulates harmful elements such as toxins, urea and excess salts over time. Kidneys facilitate the excretion of these harmful elements by filtering the bloodstream.

3. Maintain Water Levels

Kidneys adjust their function to the level of water intake. If in case the water intake drops, kidneys help retain water in the body instead of flushing it through urine.

4. Acid Regulation

The body’s environment can get acidic if the kidneys do not perform their balancing function. Kidneys filter out toxins and metals that can lead to increased acidity.

5. Red Blood Cell Stimulation

Like every organ kidneys require proper oxygenation to keep up their activity. In case of oxygen, deficiency kidneys release erythropoietin which stimulates the bone marrow and increases the production of red blood cells.

Kidney health is extremely crucial for the human body. Healthy nutrient-dense foods are necessary to maintain proper kidney function.
