Question

3) The mechanism that establishes the mecdullary osmotic gradient depends most on the of the: a nephron loop b. glomerular filtration membranc c. collecting duct d. distal convoluted tubule e. papillary duct S4. An increase in the permeability of the cells of the collecting duct to water is due to a(n) a. decrease in the production of ADH b. increase in the production of ADH c. increase in the production of aldosterone d. decrease in the concentration of the blood plasma e. increase in the production of ANP 55. Which statement describes a function of the juxtaglomerular complex (JGC)? a. release renin in response to a drop in blood pressure b. monitor NaCl concentration of filtrale c. control the diameter of the afferent arteriole d. regulate the GFR e, all of the above 56. Cells that make up which portion of the nephron have many microvilli and mitochondria? a. parictal layer of glomerular capsule b. capillaries of glomerulus c. visceral layer of glomerular capsule d. proximal convoluted tubule e distal convoluted tubule 57. The function of the renal corpuscle is: a. secrete hydrogen ions into filtrate b. create an osmotic gradient c. form glomerular filtrate from blood d. reabsorb organic nutrients e. all of the above 58. If the Tm (transport max) for a particular amino acid is 120 mg/100 ml and the concentration of that amino acid in the plasma is 230 mg/100 ml, the amino acid will be: a. actively secreted into the filtrate by PCT cells. b. completely reabsorbed by the cells of the PCT C. excreted in the urine. d. completely reabsorbed by the cells of the DCT e partially reabsorbed by cells in the nephron loop

Explanation / Answer

53- Answer-

a- Nephron Loop

54- Answer-

B - Increase in the production of ADH

ADH is an antidiuretic hormone vasopressin increase the permeability of water in collecting duct.

55- Answer-

e- All of the above

JGC has all the functions listed above.

56- Answer-

d- Proximal convoluted tubules

57- Answer-

C- Form Glomerular filtrate from the blood.

58- Answer-

b- completely reabsorbed by the cells of PCT.

Amino acid 100% reabsorbed by PCT.
