- The part of the nephron whose epithelial cells contain the longest microvilli and the most mitochondria is the (a) glomerular capsule (podocytes), (b) proximal tubule, (c) thin segment, (d) distal tubule.The only part of the nephron that originates from the embryonic ureteric bud is the (a) glomerular capsule, (b) proximal convoluted tubule, (c) nephron loop, (d) distal convoluted tubule, (e) collecting duct.This diagram illustrates which of the following Choose from the following: (A) secretion of hydrogen via Na+/H+ exchange ions by the proximal convoluted tubule (B) reabsorption of bicarbonate ions by intercalated cells (A) in the collecting duct (C) secretion of H+ by H+K+/ATPase pumps in the intercalated cells (A) in the collecting duct (D) A and B (E) all of the above
- Identify the incorrect statement about reabsorption at the nephron (A) water becomes more salty as it travels down the loop of henle(B) water gets reabsorbed through osmosis(C) aquaporins allow for the passage of water(D) the Osm is 1200 prior to entering the loop of henleHow does a) the volume b) Na + conc & c) the osmolality of the filtrate in the different regions of the nephron change?Sketch a nephron, including Bowman’s capsule, the proximal convoluted tubules, the descending and ascending loop of Henle, the distal convoluted tubules, and the collecting ducts……then…. ………Indicate where in the nephron the following diuretics and antidiuretics act: 1) osmotic diuretic (mannitol), 2) loop diuretics (furosemide or Lasix), 3) thiazide diuretics (hydrochlorothiazide), 4) potassium-sparing diuretics, 5) ADH, 6) Aldosterone

- The filtrate leaving the glomerular capsule empties into the (a) distal convoluted tubule. (b) nephron loop. (c) proximal convoluted tubule. (d) collecting duct.The structures marked by the white asterisk are identified as which of the following? Choose from the following: (A) thin segments of the nephron loop (B) vasa recta (C) glomerular capillaries (D) cortical peritubular capillaries** SELECT ALL THAT APPLY ** The descending limb of the nephron loop a) pulls water by osmosis into the lumen of the tubule b) is permeable to water only c) empties into the collecting duct d)contains fluid that becomes more and more concentrated as it moves down the tubule into the medulla e) is freely permeable to sodium and urea
