What hormone helps to maintain extracellular fluid (ecf) osmolality when concentrations become too high?

Sagot :

Vasopressin, also known as Antidiuretic hormone (ADH) helps to maintain extracellular fluid (ECF) osmolality when concentrations become too high.

When osmolality increases, it stimulates the body to produce Antidiuretic hormone (ADH). This hormone instructs the kidneys to retain more water inside the blood vessels as a result, the urine becomes more concentrated.

Osmolality refers to the concentration of dissolved particles of chemicals and minerals like sodium and other electrolytes in the serum. Osmolality increases when the body is dehydrated whereas, it decreases when too much fluid in present in the blood.

Antidiuretic hormone (ADH) or Vasopressin checks the amount of water reabsorbed from the nephrons. This regulates the water content of the blood which is termed as osmoregulation.
