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.

∙ 13y agoAldosterone 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

What is the hormone that decreases blood volume?
anp
What hormones increase blood volume and blood pressure and how?
aldosterone ADH
What is the most likely effect of a deficiency of aldosterone?
dehydration, low blood volume, low blood pressure.
What are two hormones that help maintain blood pressure by maintaing normal blood volume?
ADH and Aldosterone
How does dehydration affect aldosterone secretions?
It decreases the affect of aldosterone secretion.
What is the role of aldosterone?
Aldosterone promotes water retention and reduces urine volume
What hormone aldosterone or ADH has the greater effect on urine volume?
ADH decides the volume.Aldestorone involve in maintaining blood pressure.
What is the net result of the effect of aldosterone on the kidney nephron?
Sodium reabosorbtion increases, water follows, and ultimately blood volume is restored.
How does increased aldosterone secretion increase blood pressure?
Your body can be divided up into a number of compartments, the first two being the intracellular and extracellular compartments. The two compartments contain fluid referred to as intracellular fluid (ICF) and extracellular fluid (ECF). By convention, blood is considered part of the extracellular compartment, so it contributes to ECF. One of the major determinants of blood pressure is the volume of blood in the blood vessels. All other things being equal, if you raise blood volume, you raise blood pressure; conversely, if you lower blood volume, you lower blood pressure.Since the blood is in the extracellular compartment, the blood volume is a component of the extracellular fluid. Therefore if you raise ECF, you raise blood volume; as we saw above, raising blood volume raises blood pressure. How aldosterone contributes to blood pressure is via the regulation of ECF volume.Sodium (Na) is the major cation in the ECF. Sodium is very important for the nervous system and other parts of the body; consequently, the body works very hard to keep the blood concentration of sodium within narrow limits. If suddenly the amount of sodium in the blood were increased, your brain would trigger the sensation of thirst; you would drink water and increase the ECF volume to dilute the sodium and bring it back within the normal range. So by adding extra sodium to the blood, you increase ECF volume. And what happens to blood pressure? It increases, because ECF is a major determinant of blood pressure.What does this have to do with aldosterone?Aldosterone is a steroid hormone that's synthesized by the adrenal gland. It acts on the kidneys to increase sodium reabsorption. Having more aldosterone around means that more sodium ultimately winds up in the blood, activating thirst mechanisms that cause you to drink water, which increases ECF volume and therefore increases blood pressure.You might be interested to know that the body really does use aldosterone to regulate blood pressure. When blood pressure drops, the kidneys sense a subtle change in blood flow and start secreting an enzyme called renin. Renin works through a pathway called the renin-angiotensin-aldosterone system (RAAS; see link at left) to ultimately increase aldosterone secretion in order to return blood pressure to normal.
What does aldostrone cause?
Aldosterone is a hormone that increases the reabsorption of sodium ions and water and the release (secretion) of potassium ions in the distal convoluted tubules of the kidneys. This increases blood volume and, therefore, increases blood pressure. Drugs that interfere with the secretion or action of aldosterone are in use as antihypertensives.
How does aldosterone get to the kidneys?
Aldosterone is a hormone, so it gets to the kidneys via the blood stream.
How to increase aldosterone?
Aldosterone helps to indirectly regulate blood levels. A low sodium diet is a way to increase aldosterone in the body.
