What is the human body's response to dehydration?

Question

Quizplus · Accepted Answer

Dehydration triggers a chain of events in the body to conserve water. The hypothalamus stimulates the release of antidiuretic hormone (ADH) from the pituitary gland, which increases the permeability of the collecting ducts in the kidney, allowing for water reabsorption. At the same time, the rise in blood osmolarity triggers the thirst response, encouraging the individual to drink fluids. Additionally, the stimulation of increased aquaporin expression allows for more efficient water reabsorption in the kidneys. All of these responses work together to conserve water and prevent further dehydration.
