1. What is the primary function of the urinary system?
A. Hormone production
B. Gas exchange
C. Waste removal and fluid balance
D. Movement
Correct Answer: C
Rationale:The urinary system removes metabolic wastes and
regulates fluid and electrolyte balance.
2. Which organ filters blood to form urine?
A. Liver
B. Kidney
C. Heart
D. Lungs
Correct Answer: B
Rationale:Kidneys filter blood through nephrons.
,3. What is the functional unit of the kidney?
A. Neuron
B. Nephron
C. Alveoli
D. Glomerulus
Correct Answer: B
Rationale:Nephrons perform filtration, reabsorption, and secretion.
4. Which part of the nephron filters blood?
A. Loop of Henle
B. Glomerulus
C. Collecting duct
D. Distal tubule
Correct Answer: B
Rationale:Filtration occurs in the glomerulus.
5. Which structure collects filtrate from the glomerulus?
A. Loop of Henle
B. Bowman's capsule
C. Distal tubule
