What does the renal system do?

The renal system is responsible for the filtration and removal of waste products from the blood.

The main functions of the renal system include:

* Filtering waste products from the blood. The kidneys filter waste products from the blood and send them to the bladder in the form of urine.

* Regulating blood volume. The kidneys help to regulate blood volume by controlling the amount of water that is reabsorbed into the bloodstream.

* Regulating blood pressure. The kidneys help to regulate blood pressure by controlling the amount of sodium that is reabsorbed into the bloodstream.

* Producing erythropoietin. The kidneys produce erythropoietin, a hormone that stimulates the bone marrow to produce red blood cells.

* Regulating acid-base balance. The kidneys help to regulate acid-base balance by controlling the amount of hydrogen ions that are excreted in urine.

The renal system is essential for maintaining homeostasis in the body. It works in conjunction with other systems to ensure that the body has the proper environment to function properly.
