Not only are the kidneys considered organs of excretion, but they have an endocrine function as well as an important role in the maintenance of homeostasis through the regulation of ion concentration.

True or False?

True

Explanation:

One of the edocrine processes the kidney is involved in is called the RAAS (Renin-Angiotensin-Aldosterone System) which is a signaling pathway involved in blood pressure control. It involves a number of hormones:

Angiotensinogen is produced by the liver in response tovarious inflammatory proteins

Renin is a protease produced by the kidneys in response tohypotension,

Angiotensin II increases blood pressure via a number of mechanisms:

Aldosterone acts to increase reabsorption of Na + and water and increase elimination of K + and H + in the distal tubules of the kidneys for ion concentration maintenance
