What is ADH?
ADH, also known as antidiuretic hormone, is secreted in response to changes in body water status, such as increases in body water caused by drinking or urination or decreases in body water caused by the loss of water through perspiration.
This hormone is responsible for the sensation of thirst and the ability to retain or lose water weight. In normal individuals, ADH secretion is controlled by the body’s water balance, which is maintained through feedback loops.
ADH regulates the amount of water in the body by controlling the secretion of antidiuretic hormone (ADH). To prevent water loss, ADH tells the kidneys to retain moisture and the body’s cells. It does this by binding to receptors in the cells that control water and salt (water reabsorption) and in the cells that promote water loss (water secretion). When ADH is secreted, it causes these cells to increase their water reabsorption or decrease their water loss.
The antidiuretic hormone (ADH) is a hormone that controls the amount of urine produced by the kidneys. The amount of urine produced by the kidneys is primarily determined by the concentration of water in the blood.
What is Aldosterone?
Aldosterone is a hormone produced by the kidneys, which regulates the amount of salt and water in the body. It is primarily responsible for raising blood pressure when salt levels are low and lowering it when they are high.
It also controls the amount of water in the body and has several other functions related to maintaining its homeostasis. It is secreted in response to the hormone angiotensin and is the primary means of regulating blood pressure and fluid levels in the body.
It regulates the amount of water that is retained in the body. This helps keep the body’s blood pressure and volume within normal ranges. It is also known as a mineralocorticoid since it regulates the body’s electrolyte and water balance through its effects on the kidneys and the amount of sodium and water excreted in the urine.
When we’re young, aldosterone helps keep our body fluids balanced by stimulating the kidneys to retain sodium and excrete water. As we age, however, our aldosterone levels decline, which causes the body to have fluid and become bloated.
Difference Between ADH and Aldosterone
- ADH is a peptide hormone produced in the hypothalamus. Aldosterone is made in the adrenal glands, which sit above the kidneys.
- ADH causes the kidneys to absorb more water from the urine, which reduces urine volume and increases blood volume. On the other hand, the primary function of aldosterone is to regulate the amount of salt in the body, which is vital for keeping the right amount of fluid in the tissues.
- ADH stands for Antidiuretic hormone and Aldosterone stands for Aldosterone.
- ADH is a peptide hormone, whereas Aldosterone is a steroid hormone.
- ADH causes Dazedness, chest torment, heaving, and fever, whereas, Aldosterone causes Low pulse, weariness, and muscle shortcomings.
