,1. Multiple Choice: Which of the following structures is
responsible for the exchange of gases in the lungs?
A) Alveoli
B) Bronchi
C) Trachea
D) Diaphragm
Correct Answer: A) Alveoli
Rationale: The alveoli are the tiny air sacs in the lungs
where the exchange of oxygen and carbon dioxide takes
place.
2. Fill-in-the-Blank: The ________ valve prevents backflow
of blood into the left atrium.
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.
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) Movement
C) Blood cell production
D) Nutrient storage
Correct Answers: A) Support, B) Movement, C) Blood cell

, production, D) Nutrient storage
Rationale: The skeletal system provides structural
support, facilitates movement, houses bone marrow for
blood cell production, and stores minerals and lipids.
5. Multiple Choice: What is the primary function of the
lymphatic system?
A) Digestion of fats
B) Regulation of body temperature
C) Defense against infection
D) Production of hormones
Correct Answer: C) Defense against infection
Rationale: The lymphatic system is part of the immune
system and helps protect the body from infection and
disease.
6. Fill-in-the-Blank: Osteoclasts are cells that break down
bone tissue, a process known as ________.
Correct Answer: Bone resorption
Rationale: Osteoclasts are specialized cells that resorb or
break down bone, releasing minerals back into the blood.
7. True/False: The heart is enclosed in a double-walled sac
called the pericardium.
Correct Answer: True
Rationale: The pericardium is the protective sac that
surrounds the heart, providing it with support and
protection.
8. Multiple Response: Which of the following hormones are
produced by the anterior pituitary gland? Select all that
apply.
