What Organs In The Body Help You Maintain A Water Balance?

There are many things occurring in our body to keep our body fluids at equilibrium. A couple of them, which you asked about, are: 1. Aldosterone: The rennin-angiotensin-aldosterone system helps regulate blood pressure and blood volume. It does this by causing the kidneys to reabsorb more sodium and water and excrete potassium and hydrogen ion (H+) and therefore, lowers the volume of blood. 2. Vasopressin: Vasopressin and its analogue also help the body retain water and this helps in increasing blood volume and blood pressure. You can read more about it here: http://www.biology-online.org/7/2_vasopressin.htm.

What organ maintains water balance?

The human body contains about 60 l of water, mainly in intracellular and interstitial spaces (see cellular dehydration). The balance between intake and loss of water is important. Regulation of water balance is controlled by the hypothalamus, which secretes antidiuretic hormone (ADH), which in turn stimulates the secretion of the hormone arginine vasopressin (AVP) by the pituitary gland. AVP acts on the collecting ducts of the nephrons (the tubes that act as filters in the kidneys), then via reabsorption of water into the blood. Both ADH and AVP act on the kidney, but by different mechanisms. Since the effect of AVP is more powerful, only small amounts of ADH are required for maximal antidiuresis..

How is water balance maintained in the body?

Water balance is maintained by the mechanism as follows: as the water diffuses out of the blood; some of it is reabsorbed by the kidney and returned to the blood circulation; as the water is absorbed into the body, the body loses some water through respiration and sweat, so the balance of the body fluids is maintained by water loss through these processes..

How does kidney regulate water balance?

Kidneys regulate water balance through several mechanisms. Most notably involves regulation of blood flow to the kidney via the Starling mechanism. In the Starling mechanism, blood flow depends on the difference between blood pressure and filtrate osmotic pressure. As filtration pressure rises, blood flow rises. When filtrate pressure drops, blood flow drops. In addition to Starling mechanism, kidney can also excrete aldosterone, a hormone that causes the kidney tubules to reabsorb more sodium and water. Hence, aldosterone causes the kidneys to retain water..

How does ADH maintain water balance?

In the parathyroid gland, the PTH hormone increases the level of calcium in the blood by breaking down the bone. If the Bone is the storehouse of calcium, break down of bone releases calcium into the blood stream, and thus brings the blood calcium level to normal. If the blood calcium levels are low , parathyroid releases more PTH hormone and thus bring the blood calcium level to normal again..
