Total questions: 12
Worksheet time: 7mins
In the image of the kidney, what is A pointing at?
minor calyx
major calyx
renal pyramid
renal column
In the image of the kidney, what is B pointing at?
cortex
medulla
hilum
renal column
What is the primary function of a renal pyramid?
urine production
anchors the cortex to the kidney
pathway for urine to travel to ureter
plasma extraction in a nephron
What is the function of the distal convoluted tube?
reabsorb large organic/inorganic materials (namely sugars, amino acids, vitamins)
reabsorb water and salts
balance out blood ion concentrations
branch out to capillaries from the afferent arteriole
When is the micturition reflex typically triggered?
50 mL
200 mL
500 mL
2500 mL
What happens at the thin ascending limb?
ions (passively) go out
ions are forced out with pumps
water (passively) goes out
water is forced out with pumps
What occurs due to counter-current exchange at the loop of Henle?
urine becomes more concentrated
urine becomes diluted (more watery)
less water gets reabsorbed by the kidney
less salts get reabsorbed by the kidney
Which structure is NOT an actual part of a nephron?
Glomerulus
Bowman's capsule
Loop of Henle
Distal Convoluted Tube
The nephron structure that does some reabsorption of water/urea and provides an exit path for urine is the
collecting duct system
peritubular capillaries
proximal convoluted tube
thick ascending limb
From what to what do the ureters connect?
kidney - bladder
renal pyramid - minor calyx
cortex - medulla
minor calyx - renal pelvis
In the image, which letter points at a structure that would contain primarily urine?
A
B
C
D
What structure(s) of the nephron does caffeine and alcohol impact?
proximal convoluted tube
descending limb
thin ascending limb (both thin and thick)
collecting duct system
