BSC2086 A&P II Final Exam Questions With Complete
Solutions
A decrease in blood albumin level will cause a decrease in blood
colloid osmotic pressure; this will lead to a rise in the net
glomerular filtration pressure. Are these two statements true or
false? Correct Answers Both statements are true.
Antidiuretic hormone (ADH) causes __________. Correct
Answers a decrease in urine volume but a increase in solute
concentration
At what point in the female cycle would the corpus luteum be
prominent? Correct Answers During the luteal phase
The corpus luteum is the primary ovarian structure after
ovulation, when it secretes progesterone and estrogens.
Blood is supplied to a nephron by its __________. Correct
Answers afferent arterioles
Calculate the net filtration pressure if capillary hydrostatic
pressure is 60 mm Hg, capillary osmotic pressure is 25 mm Hg,
and capsular hydrostatic pressure is 10 mm Hg. Correct Answers
25 mm Hg
Yes, 60 - (25 + 10) = 25 mm Hg. The two pressures that oppose
filtration must be subtracted from the force favoring filtration.
Each conical, dark structure within the renal medulla is a
_______. Correct Answers renal pyramid
, If the osmotic pressure in the glomerular capillaries increased
from 28 mm Hg to 35 mm Hg, would net filtration increase or
decrease? Correct Answers net filtration would decrease
Yes, because osmotic pressure opposes filtration, increasing
osmotic pressure would decrease net filtration.
If the spinal cord were transected at a point above the sacral
region, which of the following would occur? Correct Answers
Urinary incontinence
The spinal cord above the sacral region carries impulses that
provide sensory awareness of bladder fullness, but also
voluntary control of the external urethral sphincter. Loss of this
motor pathway will cause the bladder to empty whenever it fills.
In the event of a severe increase in systemic blood pressure,
what mechanism would increase GFR? Correct Answers release
of ANP and BNP
ANP and BNP are released from the heart when an increase in
blood pressure or volume stretches the walls of the heart. Both
ANP and BNP increase GFR, which increases urine production
and reduces blood volume and pressure.
In which of the structures does reabsorption of organic
substrates occur? Correct Answers The proximal convoluted
tubule reabsorbs 99-100 percent of organic substrates.
Interstitial cells surrounding seminiferous tubules produce
testosterone in response to __________. Correct Answers LH
