BIOD 152 Exam 7 (Answered) 71 Q&A.
2025/2026. 100% Verified.
True or False: The bladder drains into the ureters.
False
A person sustained blunt force trauma to the back at the T5 level, with no spinal cord injury. Would
you suspect the kidneys to be damaged? Why or why not?
No, the kidneys lie between the T-12 and L-3
Describe the consistency and purpose of the renal fascia.
The outer renal fascia is dense fibrous connective tissue which keeps the kidney in place inside the
abdominal cavity.
Name the layer and the parts of the nephrons located in the region highlighted in green, below.
Located within the cortex are the glomerular capsule and the distal and proximal convoluted tubule
sections of the nephrons.
These arteries flow in between the renal pyramids.
A. Afferent
B. Lobar
C. Interlobular
D.Arcuate
E. Correct Answer Interlobar
F. Renal
After filtration occurs, next blood travels into these vessels.
A. Correct! Efferent arteriole
B. Lobar veins
C. Interlobular veins
D. Arcuate artery
E. Interlobar vein
F. Vasa recta
Name the region in the diagram below, indicated by the red arrow.
DCT (Distal convoluted tubule)
, Which of the following is false about the location of the bladder?
A. In males, the bladder is anterior to the rectum.
B. In females, the bladder is posterior to the uterus.
C. In females, the bladder is in between the rectum and the uterus.
D. In males, the bladder is above the prostate gland.
Correct! E. B&C are false
F. A&D are false
Describe the purposes of the urethral sphincters.
● The involuntary-controlled internal urethral sphincter is located near the bladder and keeps the
urethra closed to prevent urine from leaving the bladder.
● The voluntary-controlled external urethral sphincter, composed of skeletal muscle, surrounds the
urethra as it passes through the pelvic floor.
A patient was just placed under general anesthesia. He is now awake and telling you he is having a
hard time excreting urine. What is most likely causing the difficulty?
E. Correct! Urinary retention due to slowed detrusor muscle
This region of the male urethra exits the body.
Proststic
What causes the extremely high blood pressure in the glomerular capillaries?
The afferent arteriole, which is fed by the interlobular artery, is much larger in diameter than the
efferent arteriole. The difference in diameter causes an extremely high blood pressure in the
glomerular capillaries.
Micturition can be controlled consciously because of:
A. Voluntary control over the internal sphincter
B. Involuntary control over the internal sphincter
C. Correct! Voluntary control over the external sphincter
D. Involuntary control over the external sphincter
E. Voluntary control over the visceral reflex arc
F. None of the above: micturition cannot be voluntarily controlled
This is the pressure that depends upon a person's blood pressure from the heart and vessels:
E. Correct! Hydrostatic pressure
Calculate the net filtration pressure for your patient given the following values. Show your work.
(Not all values listed may be used).
- Colloid osmotic pressure = 25
- Capsular pressure= 15
