aldosterone is: question 5 options: 1) a hormone released by certain cells of the frontal lobe that reduces blood pressure and blood volume by inhibiting nearly all events that promote vasoconstriction and na+ and water retention. 2) a hormone produced by the adrenal cortex that regulates na+ reabsorption and k+ secretion by the kidneys. 3) a hormone released by certain cells of the heart atria that reduces blood pressure and blood volume by inhibiting nearly all events that promote vasoconstriction and na+ and water retention. 4) hormone produced by the hypothalamus and released by the posterior pituitary; stimulates the kidneys to reabsorb more water, reducing urine volume.

an adrenal cortex-produced steroid hormone (the outer layer of the adrenal gland). High blood pressure and a buildup of fluid in bodily tissues can result from an excess of aldosterone.

Aldosterone increases the amount of salt and water that the kidneys reabsorb into the blood stream, causing the blood volume to aldosterone increase, salt levels to return, and blood pressure to normal. By retaining sodium inside and releasing potassium from the body, it aids in maintaining the proper balance of water and salts in the kidney.
