How does aldosterone affect the blood volume?

Answer 1

renin is created by the kidneys which in turn converts angiotensin 1 to angiotensin 2 this stimulates the formation of aldosterone to excrete urine. I would say that it increases the urine volume to decrease the plasma volume.

Answer 2

Aldosterone acts via a similar method as it acts to increase the production of 3 types of channels:

1) sodium channels

2) potassium channels

3)sodium potassium pump (Na+/K+ATPase)

These 3 channels promote the reabsorption of sodium into the cell which in turn, pulls water with it into the cell. Potassium leaves the cell at the same rate sodium enters so it balances the cell. but sodium attracts water into the cell and potassium has no effect on water movement.

When sodium is reabsorped into the bloodstream so is the water... which overall again acts to reabsorb water from the urine, concentrating it, and increasing the amount of water in the blood

Answer 3

It stimulates the production of red blood cells. RBC count is increasesd

Answer 4

Increases of blood pressure

Answer 5

It increases the blood pressure

Answer 6
