Question

Quizplus · Accepted Answer

The urinary system does secrete the hormone erythropoietin, which regulates blood pressure, but it does not secrete the hormone renin. Renin is actually secreted by the kidneys, which are part of the urinary system, but it is specifically produced by cells in the juxtaglomerular apparatus (JGA) in the nephron.
