, Aldosterone - Answer: Trigger: decreased blood pressure; increased K levels



Function: increases reabsorption of Na from the renal tubules, causing more water to be reabsorbed via
osmosis



Result: increases blood pressure



Antidiuretic Hormone (ADH); also called vasopressin - Answer: Trigger: decreased blood volume;
increased osmolality of blood



Function: prevents fluid loss to maintain blood volume by increasing reabsorption of water from renal
tubules and collecting ducts



Result: increases blood volume



Angiotensin (Renal Hormone) - Answer: Trigger: activated by renin



Function: Constricts arteriolar blood vessels; increases reabsorption of Na and Cl and water retention in
the renal tubules ; stimulates ADH secretion



Result: increases blood pressure



Renin (Renal Hormone) - Answer: Trigger: decreased blood pressure



Function: activates angiotensin; increases secretion of ADH and aldosterone



Result: increases blood pressure



Gastric (Digestive Hormone) - Answer: Stimulus for Release: Arrival of protein in the stomach
