ADH and Water Regulation
Anti-Diuretic Hormone (ADH) is the key chemical signal that prevents you from getting dehydrated.
Which gland in the brain releases ADH?
What is ADH and Water Regulation?
"Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced."
What is the main function of the kidneys in homeostasis?
What happens if body cells lose too much water by osmosis?
Urine is produced by filtration of the blood followed by:
ADH Action
ADH makes the kidney tubules MORE permeable to water.
Released by the pituitary gland when the blood is too concentrated.
Results in more water being reabsorbed back into the blood.
Alcohol inhibits ADH, which is why it causes dehydration and more frequent urination.
