1. Which structure in the nephron filters blood plasma?
A. Loop of Henle
B. Bowman's capsule
C. Proximal tubule
D. Collecting duct
Correct Answer: B
Rationale: Bowman's capsule surrounds the glomerulus and filters
blood plasma into the nephron.
2. Which muscle type is involuntary and non-striated?
A. Skeletal
B. Cardiac
C. Smooth
D. None of the above
Correct Answer: C
Rationale: Smooth muscle is involuntary and found in walls of
hollow organs.
,3. Which hormone stimulates the thyroid gland to release T3 and
T4?
A. ACTH
B. TSH
C. GH
D. FSH
Correct Answer: B
Rationale: TSH from the anterior pituitary regulates thyroid
hormone secretion.
4. Which cranial nerve is responsible for vision?
A. Optic (II)
B. Olfactory (I)
C. Oculomotor (III)
D. Facial (VII)
Correct Answer: A
Rationale: The optic nerve transmits visual information from the
retina to the brain.
5. Which blood component transports oxygen?
A. Platelets
B. Red blood cells
C. White blood cells
D. Plasma
,Correct Answer: B
Rationale: Red blood cells contain hemoglobin, which carries
oxygen.
6. Which hormone increases blood glucose levels?
A. Insulin
B. Glucagon
C. ADH
D. Aldosterone
Correct Answer: B
Rationale: Glucagon stimulates glycogen breakdown in the liver,
raising blood glucose.
7. Which lobe of the brain processes sensory information from
touch?
A. Frontal
B. Parietal
C. Occipital
D. Temporal
Correct Answer: B
Rationale: The parietal lobe contains the somatosensory cortex.
8. Which part of the heart pumps oxygenated blood to the body?
A. Right atrium
B. Left atrium
, C. Right ventricle
D. Left ventricle
Correct Answer: D
Rationale: The left ventricle pumps oxygen-rich blood into systemic
circulation.
9. Which hormone triggers uterine contractions during labor?
A. Progesterone
B. Oxytocin
C. Estrogen
D. Prolactin
Correct Answer: B
Rationale: Oxytocin stimulates contraction of uterine smooth
muscle during childbirth.
10. Which organ secretes erythropoietin to stimulate red blood
cell production?
A. Liver
B. Kidney
C. Spleen
D. Pancreas
Correct Answer: B
Rationale: The kidneys detect low oxygen and release erythropoietin
to stimulate RBC production.
