Aldosterone release causes sodium and water retention, which causes increased blood volume, and a subsequent increase in blood pressure, which is sensed by the baroreceptors. [39] To maintain normal homeostasis these receptors also detect low blood pressure or low blood volume, causing aldosterone to be released.
The outermost layer, the zona glomerulosa is the main site for the production of aldosterone, a mineralocorticoid. The synthesis and secretion of aldosterone are mainly regulated by the renin–angiotensin–aldosterone system. The zona glomerulosa cells express a specific enzyme aldosterone synthase (also known as CYP11B2).

In humans and other animals, the adrenocortical hormones are hormones produced by the adrenal cortex, the outer region of the adrenal gland.These polycyclic steroid hormones have a variety of roles that are crucial for the body's response to stress (for example, the fight-or-flight response), and they also regulate other functions in the body.
Angiotensin also stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys. An oligopeptide , angiotensin is a hormone and a dipsogen . It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver .
In response to stress, the brain directly innervates the thyroid and pancreas for energy regulation, sends signals to the cardiovascular system to increase cardiac output, stimulates the adrenal glands to release cortisol and aldosterone, and releases hormones from the pituitary gland such as ACTH to regulate urine output through the renin ...
The alpha and beta cells are the endocrine cells in the pancreatic islets that release insulin and glucagon and smaller amounts of other hormones into the blood. Insulin and glucagon influence blood sugar levels. Glucagon is released when the blood glucose level is low and stimulates the liver to release glucose into the blood. Insulin ...
The mineralocorticoid receptor (or MR, MLR, MCR), also known as the aldosterone receptor or nuclear receptor subfamily 3, group C, member 2, (NR3C2) is a protein that in humans is encoded by the NR3C2 gene that is located on chromosome 4q31.1-31.2. [5] MR is a receptor with equal affinity for mineralocorticoids and glucocorticoids.
