Which hormones are involved in the salt water balance in human body
The hormones involved in the salt and water balance in the human body include:
1. Antidiuretic hormone (ADH) or vasopressin: This hormone is produced in the hypothalamus and released by the pituitary gland. ADH acts on the kidneys to increase water reabsorption, reducing urine output and conserving water.
2. Aldosterone: Produced in the adrenal cortex, aldosterone promotes sodium reabsorption and potassium excretion in the kidneys. It increases blood volume and maintains blood pressure.
3. Atrial natriuretic peptide (ANP): Released by the atria of the heart in response to increased blood volume and pressure, ANP promotes sodium and water excretion by the kidneys, leading to decreased blood volume and pressure.
4. Renin-angiotensin-aldosterone system (RAAS): This system is involved in regulating blood pressure and sodium balance. Renin, released by the kidneys in response to low blood pressure or low blood volume, triggers a cascade that leads to the production of angiotensin II, which stimulates the release of aldosterone.
These hormones work together to maintain a delicate balance of salt and water in the body, ensuring proper hydration and maintaining blood pressure.
