,1. Multiple Choice: Which of the following structures is
responsible for the exchange of gases in the respiratory system?
a) Trachea
b) Alveoli
c) Bronchi
d) Diaphragm
Correct Answer: b) Alveoli
Rationale: Alveoli are the tiny air sacs in the lungs where the
exchange of oxygen and carbon dioxide occurs, making them
crucial for respiration.
2. Fill-in-the-Blank: The _________ valve prevents backflow of
blood into the left atrium during ventricular contraction.
Correct Answer: Mitral
Rationale: The mitral valve, also known as the bicuspid valve, is
located between the left atrium and left ventricle and prevents the
backflow of blood during ventricular systole.
3. True/False: The axial skeleton includes the bones of the arms
and legs.
Correct Answer: False

, Rationale: The axial skeleton consists of the skull, vertebral
column, ribs, and sternum. The appendicular skeleton includes the
bones of the arms and legs.
4. Multiple Response: Select all that apply. Which of the following
are functions of the skeletal system?
a) Support
b) Storage of minerals
c) Production of blood cells
d) Regulation of body temperature
Correct Answers: a) Support, b) Storage of minerals, c)
Production of blood cells
Rationale: The skeletal system provides structural support, stores
minerals like calcium and phosphorus, and contains bone marrow,
which produces blood cells. It does not regulate body temperature.
5. Multiple Choice: In the cardiac cycle, the period of ventricular
relaxation is called:
a) Systole
b) Diastole
c) Ischemia
d) Hypertrophy
Correct Answer: b) Diastole
