Question
1. 3 of the following are true of the Renin Angiotensin Aldosterone System (RAAS) A. The JG cells are located at the distal collecting tubule B. The Juxtaglomerular cells (JG cells) are modified smooth muscles in the afferent arteriole C. The Macula densa detects osmolality of the filtrate D. The Macula densa is made up of tall columnar cells 2. 2 of the following are true of the RAAS responding to a decrease in Na in the filtrate A. Macula densa detects the decrease in osmolality B. JG cells are stimulated by Macula densa through tight junctions C. Aldosterone stimulates principal cells of collecting tubule to reabsorb water D. Aldosterone reabsorbs Na and by osmotic forces increase fluid in the extracellular compartment 3. 2 of the following are true of the loop of Henle A. Descending thick limb is also called the pars recta of the proximal tubule B. The function of the descending thick limb is similar to the distal convoluted tubule C. Cells of the descending thin limb are very permeable to water due to Aquaporin I D. The pars recta of the distal tubule has a prominent brush border 4. 2 of the following are true of the renal glomerulus A. Mesangial cells are capable of phagocytosis to keep the filter free of debris and proteins B. The parietal layer of the bowmans capsule is lined by podocytes C. The Filtration slits are formed by adjacent pedicels D. The visceral layer of bowmans capsule is lined by simple squamous epithelium 5. 2 of the following are true of collecting tubules A. Principal cells are responsible for the ability of the kidneys to concentrate urine B. a-intercalated cells release HCO3 into the tubular lumen C. B-intercalated cells release acid into the tubular lumen D. a-intercalated cell perform their function in response to acidosis 6. 3 of the following are true of glomerulonephritis A. Results from deposition immune complexes in the glomerular basal lamina B. Commonly due to a streptococcal infection elsewhere in the body C. Leucocyte infiltration is rare D. Results in reduction in filtering ability
