Chapter 1: An Introduction to the Human Body
1. A 45-year-old male presents to the emergency department with severe abdominal pain.
An ultrasound reveals an inflammation of the membrane directly adhering to the surface of
the liver. Which specific structure is affected?
A. Parietal pleura
B. Visceral peritoneum
C. Parietal peritoneum
D. Visceral pleura
Answer>>B
Explanation: The liver is located in the abdominopelvic cavity. Serous membranes consist
of two layers: the parietal layer (lining the cavity wall) and the visceral layer (covering the
organ). The visceral peritoneum is the specific serous membrane in direct contact with
abdominal organs like the liver.
2. During a clinical trial for a new antihypertensive medication, researchers observe that
the drug works by enhancing the body’s ability to detect high blood pressure and
subsequently stimulating a decrease in heart rate. This mechanism is an example of:
A. Positive feedback
B. Feed-forward regulation
C. Negative feedback
D. Set point deviation
Answer>>C
Explanation: Negative feedback loops work to reverse a deviation from the set point,
maintaining homeostasis. By detecting high blood pressure and triggering a response
(lowering heart rate) to bring it back toward the normal range, the body is utilizing a
negative feedback mechanism.
3. A surgeon is performing a laparoscopic cholecystectomy (gallbladder removal). To
access the gallbladder, the surgeon must make an incision in which abdominopelvic
quadrant?
, 4
A. Right Upper Quadrant (RUQ)
