Which hormone, secreted by the adrenal cortex, reabsorbs sodium and fluid at the level of the kidneys?
Aldosterone is a hormone that is secreted by the endocrine system. 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; however, it does not reabsorb sodium and fluid at the level of the kidneys.
- Antidiuretic hormone
While antidiuretic hormone plays a huge role in the maintenance of fluid balance homeostasis within the body, it does not reabsorb sodium and fluid at the level of the kidneys.
- Adrenocorticotropic hormone
Adrenocorticotropic hormone (ACTH) is made in the pituitary gland, a structure of the endocrine system. It is needed for the adrenal glands to work properly and helps the body react to stress; this hormone does not play a role in fluid balance.
The endocrine system works in conjunction with the renal system to maintain an appropriate fluid balance within the human body.
Hormones that are controlled by the endocrine system work in conjunction with the renal system to maintain fluid homeostasis within the body. Aldosterone is an example of one of these endocrine hormones. It is secreted by the adrenal cortex and reabsorbs fluid and sodium at the level of the kidneys.
