Physiological AdaptationQuestion 220 of 2368

A client loses blood, and the blood pressure falls. Which hormone action helps raise blood volume by increasing sodium reabsorption in the kidneys?

  1. Renin released from the liver
  2. Antidiuretic hormone released from the thyroid
  3. Insulin released from the pancreas
  4. Aldosterone released from the adrenal cortex
Show answer

Correct answer: Aldosterone released from the adrenal cortex

Angiotensin II stimulates aldosterone release. Aldosterone increases sodium reabsorption, and water follows salt, raising blood volume and pressure.
