Question 1
Which part of the nephron is located closest to the collecting duct?
A) Bowman's capsule
B) Proximal convoluted tubule
C) Loop of Henle
D) Distal convoluted tubule
E) Glomerulus
Correct Answer: D) Distal convoluted tubule
Rationale: In the sequence of the nephron, filtrate moves from the glomerulus to the
proximal tubule, through the loop of Henle, into the distal convoluted tubule, and finally
into the collecting duct.
Question 2
Which blood vessels carry deoxygenated blood directly into the right atrium of the heart?
A) Pulmonary veins
B) Aorta
C) Pulmonary arteries
D) Superior and inferior vena cavae
E) Coronary arteries
Correct Answer: D) Superior and inferior vena cavae
Rationale: The superior vena cava drains deoxygenated blood from the upper body, and the
inferior vena cava drains deoxygenated blood from the lower body; both empty into the
right atrium.
Question 3
Which part of the central nervous system is responsible for the control of involuntary
respirations?
A) Cerebrum
B) Cerebellum
C) Medulla oblongata
D) Thalamus
E) Hypothalamus
Correct Answer: C) Medulla oblongata
Rationale: The medulla oblongata contains the respiratory centers that regulate the rhythm
and depth of breathing involuntarily.
Question 4
Which structure prevents food from being aspirated into the lungs during swallowing?
A) Larynx
B) Pharynx
, 2
C) Epiglottis
D) Esophagus
E) Trachea
Correct Answer: C) The epiglottis
Rationale: The epiglottis is a cartilaginous flap that folds over the glottis (opening to the
larynx) during swallowing to redirect food into the esophagus.
Question 5
How does the event of ovulation take place in the female reproductive system?
A) The corpus luteum dissolves, releasing an egg.
B) The Graafian follicle ruptures, releasing an ovum.
C) The endometrium sheds, pushing an egg out.
D) The fallopian tubes contract to pull an egg from the ovary.
E) Estrogen levels drop suddenly to trigger egg release.
Correct Answer: B) It takes place as the Graafian follicle ruptures, subsequently releasing
an ovum
Rationale: Ovulation occurs when a mature (Graafian) follicle bursts in response to a surge
in luteinizing hormone (LH), releasing the secondary oocyte.
Question 6
Straightening the elbow by lowering the hand involves the contraction of which muscle?
A) Biceps brachii
B) Brachialis
C) Triceps brachii
D) Deltoid
E) Pectoralis major
Correct Answer: C) Triceps brachii
Rationale: The triceps brachii is the primary extensor of the elbow joint; when it contracts,
it straightens the arm.
Question 7
The production of which substance is a primary function of the prostate gland?
A) Testosterone
B) Estrogen
C) Fluid to enhance sperm motility
D) Luteinizing hormone
E) Concentrated urine
Correct Answer: C) The substance to enhance sperm motility
Rationale: The prostate gland secretes a slightly alkaline fluid that makes up part of the
semen and contains enzymes that help sperm survive and move effectively in the female
reproductive tract.
