Aldosterone acts on what part of the kidney?
Aldosterone acts on the distal convoluted tubule and collecting duct in the kidney to increase sodium reabsorption and potassium secretion.
Which of the choices below are the most important hormone regulators of electrolyte reabsorption and secretion?
The most important hormone regulators of electrolyte reabsorption and secretion are aldosterone and antidiuretic hormone (ADH). Aldosterone acts on the kidneys to increase sodium reabsorption, while ADH acts on the kidneys to increase water reabsorption. Together, these hormones help regulate electrolyte balance in the body.
Which hormone aids in regulating the levels of salt and water in the body?
Aldosterone is the primary hormone that aids in regulating the levels of salt and water in the body by acting on the kidneys to increase the reabsorption of sodium and water, thereby helping to maintain blood pressure and electrolyte balance.
Which hormone plays a central role in determining the rate of sodium reabsorption and potassium secretion?
Aldosterone is the hormone that plays a central role in determining the rate of sodium reabsorption and potassium secretion in the kidneys. Aldosterone acts on the distal convoluted tubules and collecting ducts of the kidney to increase sodium reabsorption and potassium secretion.
What is the primary stimulus for the secretion of aldosterone?
The primary stimulus for the secretion of aldosterone is low blood pressure or low blood volume, which are detected by special cells in the kidneys. The renin-angiotensin-aldosterone system is then activated to increase aldosterone secretion from the adrenal glands, leading to increased reabsorption of sodium and water by the kidneys to help restore blood pressure and volume.
What drug blocks the effects of aldosterone?
Caffeine binds to aldosterone sites and thus causes an increase of aldosterone in the blood. This increase causes sodium re-absorption and potassium excretion. Sodium excites nerves as potassium relaxes them. This is why one looses their nerve with too much caffeine.
What does aldosterone increase in the basolateral membrane?
Basolateral Na+ K+ ATPase pumps
Is aldosterone released when someone is dehydrated?
No,ADH is released.It increase reabsorption of water.
What hormones increase blood volume and blood pressure and how?
aldosterone ADH

Aldosterone acts on the kidneys to increase sodium reabsorption, while ADH acts on the kidneys to increase water reabsorption. Together, these hormones help regulate electrolyte balance in the body.
The main region of aldosterone action is the?
The main region of aldosterone action is the distal convoluted tubule (DCT) and collecting duct of the kidneys. It functions to increase sodium reabsorption as well as enhance potassium excretion. The net effect of this is an increase in blood volume (via increased reabsorption of water), and thus an increase in blood pressure.
Excess blood potassium hyperkalemia is removed by increasing secretion of the hormone which stimulates an increase in the secretion of potassium by cells within the?
Excess blood potassium (hyperkalemia) is typically removed by increasing the secretion of aldosterone. Aldosterone stimulates the kidneys to increase the secretion of potassium by cells within the kidney nephrons, promoting the excretion of excessive potassium from the body through urine.
Which hormone aids in regulating the levels of salt and water in the body?
Aldosterone is the primary hormone that aids in regulating the levels of salt and water in the body by acting on the kidneys to increase the reabsorption of sodium and water, thereby helping to maintain blood pressure and electrolyte balance.

What is the roleof aldosterone?
Aldosterone will cause Na+ to be absorbed from a filtrate
