A&P.Ch.15 Urinary system H.W

1. : produced by juxtaglomerular cells Renin Antidiuretic hormone angiotensin ll aldosterone

Renin

When the juxtaglomerular cells in the kidney are, they produce and secrete the enzyme renin into the blood. What subsequent changes take place by this mechanism? Renin released Angiotensin II activated Adrenal cortex stimulated Aldosterone released Kidney tubules increase sodium uptake Blood volume increases

Renin released Angiotensin II activated Adrenal cortex stimulated Aldosterone released Kidney tubules increase sodium uptake Blood volume increases

_________: leads to _____ formation in the blood

Renin; Angiotensin II

Which of the following is NOT a correct description of the hilum of the kidney? -The hilum is on the most superior surface of the kidney. -The hilum is where the ureter exits the kidney. -Renal blood vessels and nerves enter and exit the hilum. -The hilum is the concave indention of the kidney.

The hilum is on the most superior surface of the kidney
