Functions of the Kidney

What the kidneys do

The human kidney is a small biological miracle with an intriguing design and function. It plays a vital role in the body since it is a significant part of the metabolic process. Kidneys come in pairs and are each about eleven centimeters long in an adult and weigh an average of 160 grams.

Kidneys remove excess water and detoxify the body

The kidneys create urine, which is excreted through the urinary tract. The urine is also used to remove excess water from the body as well as many toxins. The organs also regulate the acid-base balance in the body, preventing the acidification of the blood.

Kidneys control vital bodily functions

Kidneys also play a key role in the regulation of blood pressure. This is controlled by various hormones that are produced in the kidneys. Another hormone produced by these organs is Erythropoietin, which controls the production of red blood cells in the bone marrow. In addition, the kidneys also adjust calcium levels and play an important part in the production of vitamin D, which contributes to strong bones.
