SECTION 1: Anatomy & Physiology (Questions 1-40)
1. Which of the following is the primary function of the skeletal system?
A. Production of hormones
B. Protection of internal organs
C. Transportation of oxygen
D. Filtration of blood
Correct Answer: B
Rationale: The skeletal system provides structural support and protects vital organs
(e.g., skull protects brain, ribs protect heart and lungs). Hormone production is primarily
endocrine; oxygen transport is cardiovascular; blood filtration is renal.
2. The chamber of the heart that receives oxygenated blood from the lungs is the:
A. Right atrium
B. Right ventricle
C. Left atrium
,D. Left ventricle
Correct Answer: C
Rationale: The left atrium receives oxygenated blood via the pulmonary veins. The right
side receives deoxygenated blood. The left ventricle pumps oxygenated blood to the
body.
3. Which structure connects muscles to bones?
A. Ligaments
B. Cartilage
C. Tendons
D. Fascia
Correct Answer: C
Rationale: Tendons connect muscle to bone. Ligaments connect bone to bone.
Cartilage provides cushioning at joints. Fascia surrounds muscles.
4. The basic functional unit of the kidney is the:
A. Neuron
B. Nephron
C. Alveolus
D. Villus
Correct Answer: B
, Rationale: The nephron is the microscopic filtering unit of the kidney. Neurons are nerve
cells; alveoli are lung air sacs; villi are intestinal absorptive structures.
5. Which gland is often referred to as the "master gland" of the endocrine system?
A. Thyroid gland
B. Adrenal gland
C. Pituitary gland
D. Pancreas
Correct Answer: C
Rationale: The pituitary gland regulates other endocrine glands (thyroid, adrenals,
gonads) through its hormones, earning it the "master gland" designation.
6. In which body cavity is the heart located?
A. Abdominal cavity
B. Cranial cavity
C. Thoracic cavity
D. Pelvic cavity
Correct Answer: C
Rationale: The heart is located in the mediastinum of the thoracic cavity, between the
lungs. The abdominal cavity contains digestive organs; cranial contains the brain.
