BIOD 152 MODULE 7 UPDATED QUESTION AND
ANSWERS 2024/2025
T/F: The kidneys are long, thin muscular tubes
False
T/F: 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 expect the kidneys to be damaged? Why or why not?
No, the kidneys lie between T-12 and L-3
Describe the consistency and purpose of the renal capsule
The renal capsule is a tough fibrous outer skin of the kidney which protects it from injury
and infection
Describe the consistency and purpose of the renal adipose capsule
Outside of the renal capsule is a fatty layer that protects the kidney from trauma
Describe the consistency and purpose of the renal fascia
The outer renal fascia is composed of dense, fibrous CT which functions to anchor the
kidney in place in the abdominal cavity
Renal medulla sections
The renal medulla is divided into sections called pyramids that point toward the center
of the kidney
Outer layer of the kidney and the parts of the nephrons located in this region
Cortex- located within the cortex are the glomerular capsule and the PCT and DCT
sections of the nephrons
These arteries flow in between the renal pyramids
Interlobar arteries
After filtration occurs, next blood travels into these vessels
Efferent arterioles
Which of the following is true about the location of the bladder?
A. In males, the rectum is anterior to the bladder
B. In females, the vagina is behind the bladder
C. In females, the bladder sits above the uterus
D. In males, the bladder is below the prostate gland
E. B&C are true
F. A&D are true
B. In females, the vagina is behind the bladder
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 glands
E. B&C are false
F. A&D are false
, E. B&C are false:
In females the bladder is posterior to the uterus & in females, the bladder is between the
rectum and the uterus
Describe the purpose of the urethral sphincters
-Involuntarily-controlled internal urethral sphincter is located near the bladder and keeps
the urethra closed to prevent urine from leaving the bladder
-Voluntarily-controlled external urethral sphincter is composed of skeletal muscle and
surrounds the urethra as it passes through the pelvic floor
Based strictly on anatomical structural differences, are males or females more
likely to get a UTI? Explain your answer
Females, the female urethra is shorter and only carries urine while the male urethra is
about 5 times longer. Since the female urethra is short and the external opening is close
to the anus, improper wiping or poor hygiene after defecation can easily carry fecal
bacteria into the urethra. Bacteria enter the urethra and travel up to the bladder, causing
a urinary tract infection (UTI).
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?
Urinary retention due to slowed detrusor muscle
This region of the male urethra exits the bladder
Prostatic
This region of the male urethra exits the body
Spongy
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:
Voluntary control over the external urethral sphincter
Describe the difference between the two types of nephrons
Cortical nephrons are in the cortex region of the kidney, except for a portion of their loop
of henle which extends into the medulla.
Justamedullary nephrons pass deeply into the medulla because of their location and
their longer loops of henle
For micturition to occur
The internal sphincter relaxes and the external sphincter relaxes
This is the pressure that depends upon the amount of proteins in the filtrate
Colloid osmotic pressure
This is the pressure that depends upon a person's blood pressure from the heart
and vessels
Hydrostatic pressure
Calculate the NFP for your patient given the following values
COP: 25
Capsular pressure: 15
Hydrostatic pressure: 50
GFR: 120
