Correct Answer: B. Kidney
Rationale: The kidneys remove waste products and excess water from the blood to form urine.
Question 4
The functional unit of the kidney is the:
A. Alveolus
B. Nephron
C. Neuron
D. Villus
Correct Answer: B. Nephron
Rationale: Each kidney contains about one million nephrons, which filter blood and produce
urine.
Question 5
Which blood vessel carries oxygen-rich blood from the lungs to the heart?
A. Pulmonary artery
B. Aorta
C. Pulmonary vein
D. Superior vena cava
Correct Answer: C. Pulmonary vein

Question 6
Which vitamin is produced in the skin when exposed to sunlight?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K
Correct Answer: C. Vitamin D
Rationale: Sunlight triggers the production of vitamin D, which supports calcium absorption and
bone health.
Question 7
Which body system is primarily responsible for regulating hormones?
A. Respiratory system
B. Endocrine system
C. Digestive system
D. Muscular system
Correct Answer: B. Endocrine system
