1. Which of the following structures is primarily involved in gas
exchange within the lungs?
- A) Trachea
- B) Bronchi
- C) Alveoli
- D) Pleura
Correct ANS: C) Alveoli
Rationale: Alveoli are the tiny air sacs in the lungs where
oxygen and carbon dioxide are exchanged.

,2. What is the primary function of the renal corpuscle in the
nephron?
- A) Filtration of blood
- B) Reabsorption of glucose
- C) Secretion of hormones
- D) Regulation of blood pH
Correct ANS: A) Filtration of blood
Rationale: The renal corpuscle is responsible for filtering blood
to form urine.
3. Which type of muscle tissue is characterized by striations and
voluntary control?
- A) Cardiac muscle
- B) Smooth muscle
- C) Skeletal muscle
- D) Connective muscle
Correct ANS: C) Skeletal muscle
Rationale: Skeletal muscle is striated and under voluntary
control, unlike cardiac and smooth muscle.

,4. The primary pacemaker of the heart is located in which part of
the heart?
- A) Atrioventricular node
- B) Bundle of His
- C) Sinoatrial node
- D) Purkinje fibers
Correct ANS: C) Sinoatrial node
Rationale: The sinoatrial node is responsible for initiating the
electrical impulses that regulate heartbeats.
5. Which part of the brain is primarily responsible for
coordination and balance?
- A) Cerebrum
- B) Brainstem
- C) Cerebellum
- D) Thalamus
Correct ANS: C) Cerebellum
Rationale: The cerebellum coordinates voluntary movements
and balance.

, 6. The functional unit of the kidney is the ________.
Correct ANS: nephron
Rationale: Nephrons are the structural and functional units that
perform the essential functions of the kidney, including filtration.
7. The region of the brain that connects the two hemispheres is
known as the ________.
Correct ANS: corpus callosum
Rationale: The corpus callosum is a thick band of nerve fibers
that facilitates communication between the left and right
hemispheres of the brain.
8. The ________ system is responsible for transporting oxygen,
nutrients, and hormones throughout the body.
Correct ANS: cardiovascular
Rationale: The cardiovascular system, comprising the heart and
blood vessels, plays a critical role in systemic circulation.
9. The ________ membrane surrounds the lungs and is crucial
for reducing friction during respiration.
Correct ANS: pleural
Rationale: The pleural membrane consists of two layers that
provide a lubricated surface, facilitating lung expansion and
contraction.
