Concerning angiotensin II:
A. the exocrine renin-angiotensin-aldosterone system includes
angiotensinogen production by the liver, renin secretion by the
juxtaglomerular apparatus and angiotensin-converting enzyme present
at the luminal surface of endothelial cells
B. aldosterone, but not AII, stimulate thirst and salt appetite
C. angiotensin II induces marked increases in sodium reabsorption by
the loop of Henle and the collecting duct
D. A and C are correct
E. all are correct Ans✓✓✓ A. the exocrine renin-angiotensin-
aldosterone system includes angiotensinogen production by the liver,
renin secretion by the juxtaglomerular apparatus and angiotensin-
converting enzyme present at the luminal surface of endothelial cells
Concerning the function of the proximal tubule:
, A. most of the glomerular ultrafiltrate is reabsorbed in the proximal
tubule in an iso-osmotic fashion.
B. the concentration of PAH doesn't change much along the length of
the proximal tubule
C. under normal conditions, most of the filtered glucose and
bicarbonate are reabsorbed in the proximal tubule
D. A and C are correct
E. all are correct Ans✓✓✓ D. A and C are correct
Concerning the functional histology of the kidney:
A. the superficial nephrons have short loops of Henle; thus, they have a
low capacity to reabsorb salt (salt losing nephrons)
B. the deep nephrons have long loops of Henle; thus they have a high
capacity to reabsorb salt and water
C. in dehydration, the blood flow to deep nephrons tends to increase
