Which substance is produced by the kidneys in response to the body’s blood pressure in an effort to maintain homeostasis?
Renin, an enzyme, is produced by the kidneys. Its function is to maintain the body’s blood pressure in an effort to maintain homeostasis.
Aldosterone is a hormone that is secreted by the endocrine system. Specifically, it is secreted by the adrenal cortex and it acts on the kidney to save, or rid, the body of sodium and water.
- Angiotensin II
Angiotensin II is an endocrine enzyme that assists the renal system in maintaining fluid balance within the body
- Antidiuretic hormone
While antidiuretic hormone plays a huge role in the maintenance of fluid balance homeostasis within the body. It is not, however, produced by the kidneys in response to the body’s blood pressure.
Homeostasis is the state of steady chemical, internal, and physical conditions maintained by living systems.
Renin, along with the angiotensins, is the part of the Renin-Angiotensin cycle. This cycle supports the cardiac system’s blood pressure, electrolytes and circulating blood volume at the level of the kidneys. The enzyme renin is produced by the kidneys according to the blood pressure (e.g., it is either stimulated or suppressed in response to blood pressure).
