Question
Match each hormone or enzyme with its site of production and function in regulating fluid and electrolyte balance.
Hormone/Enzyme
1) vasopressin
2) aldosterone
3) renin
4) angiotensin II
5) atrial natriuretic peptide (ANP)
Production Site and Function
a. Hormone produced in atrial cells of the heart; functions to inhibit sodium reabsorption in the kidney, thereby promoting fluid loss.
b. Hormone produced in hypothalamus; functions to conserve water by increasing reabsorption of water by the kidneys.
c. Hormone produced in adrenal cortex; functions to stimulate active reabsorption of sodium by the kidneys, thereby promoting fluid retention. d. Enzyme produced by kidney; functions to hydrolyze angiotensinogen to angiotensin I.
e. Active hormone produced by angiotensin-converting enzyme in the lungs; functions as vasoconstrictor, as stimulator for release of aldosterone, and as stimulator of hypothalamus to release vasopressin.
