What would a rise in angiotensin II levels would result in?
increase in water retension
Which hormone limits sodium excretion in the urine to help maintain your electrolyte balances during excessive sweating?
Aldosterone is the hormone that limits sodium excretion in the urine. It is released by the adrenal glands in response to low blood pressure or low blood sodium levels. Aldosterone acts on the kidneys to increase the reabsorption of sodium and water, helping to maintain electrolyte balance during excessive sweating.
If a tumor of the glucocorticoid-secreting cells of the adrenal cortex crowds out the cells that produce aldosterone what is the likely effect on urine composition and volume?
increase urine composition and increace volume
Which hormone aids in regulating the levels of salt and water in the body?
Aldosterone is a mineralocoricoid hormone secreted by the adrenal cortex.
What is the name of the hormone that promotes sodium retention and potassium secretion?
Natriuretic hormones
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
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.
What would a rise in angiotensin II levels would result in?
increase in water retension
What is the roleof aldosterone?
Aldosterone will cause Na+ to be absorbed from a filtrate
What is the role of aldosterone?
Aldosterone promotes water retention and reduces urine volume
How does dehydration affect aldosterone secretions?
It decreases the affect of aldosterone secretion.
How does aldosterone get to the kidneys?
Aldosterone is a hormone, so it gets to the kidneys via the blood stream.
Which hormone limits sodium excretion in the urine to help maintain your electrolyte balances during excessive sweating?
Aldosterone is the hormone that limits sodium excretion in the urine. It is released by the adrenal glands in response to low blood pressure or low blood sodium levels. Aldosterone acts on the kidneys to increase the reabsorption of sodium and water, helping to maintain electrolyte balance during excessive sweating.
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?
aldosterone; cortical collecting duct
