Anatomy & Physiology Question #44


Which hormones are released from the kidney and heart?


  1. Estrogen and progesterone
    • Rationale:
  2. Insulin and glucagon
    • Rationale:
  3. Renin and angiotensinogen
    • Rationale:
  4. Erythropoietin and atrial natriuretic peptide (ANP)
    • Rationale:



The correct answer is D. Erythropoietin is released in response to hypoxia (low levels of oxygen at tissue level) in the renal circulation. It stimulates erythropoiesis (production of red blood cells) in the bone marrow. ANP is a cardiac hormone which has the main function of lowering blood pressure and controlling electrolyte homeostasis. Estrogen, progesterone, insulin, glucagon, renin, and angiotensin are not hormones released from the kidney and the heart.
