MEDSCI 142 - Renal Exam Questions And Correct AnswersRegarding renal corpuscles
a) the capsular space empties directly into the distal convoluted tubule
b) the glomerular filter is made up of the following: capillary endothelial cells, basement
membrane, outer capsule
c) capillary endothelial cells are termed podocytes
d) the renal corpuscles are all located in the medulla of the kidney
e) the endothelium of the glomerular capillaries has pores - ANSWER a - no, the
ascending loop of henle feeds into the distal convoluted tubule
b - no, outer capsule is nonexistent, there is only a slit membrane present
c - no, they are epithelium
d - no, they are located in the cortex
e - correct, it is fenestrated enodthelium
Choose the correct statement regarding human kidney:
a) cells lining the proximal convoluted tubule of the nephron are the only cells of the
body that have a brush border of microvilli; b) the ureter is contiguous with the renal
pelvis; c) there are more lobes than lobules in the human kidney; d) the glomerular
[Bowmans] capsule is in direct contact w/ blood.
e) the urinary space of the renal corpuscle is continuous with the distal convoluted tube
- ANSWER a - no, there are lots around the bodyb - correct, the renal pelvis continues to
become the ureterc - no, there are many many lobules in each lobed - no, it is the
outside parts of the renal corpuscle
e - no, the distal convoluted tubule does not connect with the renal corpuscle
Which of the following statements about human kidney is TRUE?
a) renal columns are composed of medullary tissue
b) renal artery enters the kidney and immediately divides into the interlobular arteries
,c) the sequence of flow of the fluid entering the nephron and the collecting duct in the
following order: glomerular capsule (surrounding the glomerulus)-proximal convoluted
tubule-distal convoluted tubule-loop of Henle-collecting duct
d) the path of urine drainage in the human kidney in the following order: renal
pyramid-minor calyx-major calyx-renal pelvis-ureter
e) sequence of the urinary pathway in a kidney is as follows: renal pyramidrenal
pelvismajor calyxminor calyxureterurinary bladder - ANSWER a - no they are composed
of cortex tissue
b - no, there are other branches that arise before it
c - no, its sequence is after the loop of Henle
d - correct
e - no, the calyces appear before the pelvis does
Which one of the following is found ONLY in the renal pyramid?
a) afferent arteriole
b) renal column
c) vasa recta
d) proximal convoluted tubule
e) glomerulus - ANSWER a - no, this is in the cortex going into the capsule
b - no, this is a supporting structure next to it
c - correct, it runs alongside the loop of Henle
d - no, this is in the cortex
e - no, this is in the cortex
Glomerular capillary endothelial cells of the kidney are found within the:
a) minor calyx
b) collecting duct
c) proximal tubule
d) vasa recta
e) renal corpuscle - ANSWER e - this is the only structure that is associated directly with
, the glomerulus
The part of a juxtamedullary nephron that is in the renal medulla is the:
a) loop of Henle
b) entire nephron
c) renal corpuscle
d) glomerular (Bownmans) capsule only
e) glomerulus only - ANSWER a - correct by elimination
b - no, part is is the cortex as well
c - no, this is in the cortex
d + e - these are both part of the renal corpuscle in the cortex
Which of the following statements about the nephron of the human kidney are correct?
a) the route of flow of fluid in the nephron is the following: glomerular capsule-distal
convoluted tubule-proximal convoluted tubule-collecting duct
b) the single layer of epithelial cells lining the tubular portions of the nephron are
involved in the transport of material either from the lumen of the tubule to the capillaries
surrounding the tubule, or vice versa. c) blood vessels surround the nephron tightly in
the cortex, while the vessels in the medulla are less tight. d) the glomerular filter is made
up of the following structures: endothelial cells with pores, basement membrane, and
epithelial cells with microvilli
e) path of fluid flow through the nephron is: glomerular capsule-proximal convoluted
tubule-loop of Henle-collecting duct-distal tubule - ANWER a - no, proximal tubule is
before distal
b - correct by elimination, and single layer cells perform transport and diffusion
c - no, the other way around
d - no, there are no microvilli
e - no, distal tubule comes before collecting duct
Which of the following list the vessels in correct order of blood flow?
