Which hormone is not matched correctly with its principal action? (A) gastrin - increases stomach movement (B) erythropoietin (EPO) - increases white blood cell production (C) leptin - suppresses appetite (D) atrial natriuretic peptide (ANP) - lowers blood pressure (E) estrogens - prepare mammary gland to secrete milk

The correct answer is: (B) erythropoietin (EPO) - increases white blood cell production.

Explanation:

Erythropoietin is a hormone secreted by the kidney when dealing to cellular hypoxia (low oxygen content on body tissues) to stimulate red blood cell production. This is because red blood cells are the ones that transport oxygen to every tissue in the body.
