- Renin — secreted by the juxtaglomerular cells of the kidney; it initiates the renin-angiotensin-aldosterone pathway that raises blood pressure when renal blood flow/pressure falls. TRUE, kidney hormone.
- Gastrin — secreted by G-cells of the stomach (pyloric region), stimulates gastric acid secretion. NOT a kidney hormone.
- Calcitriol — the active, hormonal form of vitamin D, produced by the kidney (via hydroxylation of a vitamin D precursor); it promotes intestinal calcium absorption. TRUE, kidney hormone. …
