MULTIPLE-CHOICE QUESTIONS WITH
RATIONALES!!!
Section 1: Anatomy & Physiology (Questions 1-30)
1. Which of the following structures is responsible for filtering blood in the
kidney?
A) Loop of Henle
B) Glomerulus
C) Collecting duct
D) Bowman's capsule
Correct Answer: B) Glomerulus
Rationale: The glomerulus is a network of capillaries that filters blood,
allowing water and small solutes to pass into Bowman's capsule while
retaining larger molecules like proteins and blood cells. The Loop of Henle and
collecting duct are involved in concentration and reabsorption, while
Bowman's capsule collects the filtrate.

,2. What is the primary function of the mitochondria?
A) Protein synthesis
B) ATP production through cellular respiration
C) Lipid synthesis
D) Storage of genetic material
Correct Answer: B) ATP production through cellular respiration
Rationale: Mitochondria are the powerhouses of the cell, generating ATP
through oxidative phosphorylation. The endoplasmic reticulum is involved in
protein and lipid synthesis, while the nucleus stores genetic material.

3. Which hormone regulates blood glucose levels by promoting the uptake of
glucose into cells?
A) Glucagon
B) Cortisol
C) Insulin
D) Thyroxine
Correct Answer: C) Insulin
Rationale: Insulin, secreted by pancreatic beta cells, promotes glucose uptake,
glycogen synthesis, and lowers blood glucose. Glucagon raises blood glucose,
cortisol increases glucose production during stress, and thyroxine regulates
metabolism.

,4. The sinoatrial node is located in which part of the heart?
A) Left ventricle
B) Right atrium
C) Right ventricle
D) Left atrium
Correct Answer: B) Right atrium
Rationale: The sinoatrial (SA) node, the heart's natural pacemaker, is located
in the right atrial wall. It generates electrical impulses that initiate heart
contractions, setting the rhythm for the entire heart.
---
5. Which type of joint allows for rotational movement, such as turning the
head?
A) Ball-and-socket joint
B) Hinge joint
C) Pivot joint
D) Saddle joint
Correct Answer: C) Pivot joint
Rationale: Pivot joints allow rotational movement around a single axis, such as
the atlas rotating around the dens of the axis for head rotation. Ball-and-
socket allows multi-directional movement, hinge allows flexion/extension,
and saddle allows movement in two planes.

6. What is the role of the alveoli in the respiratory system?
A) Transport oxygen to the blood
B) Exchange gases between air and blood
C) Warm and humidify incoming air
D) Trap dust and pathogens
Correct Answer: B) Exchange gases between air and blood
Rationale: Alveoli are tiny air sacs where gas exchange occurs via diffusion.
Oxygen moves from air to blood, and carbon dioxide moves from blood to air.
The trachea warms and humidifies air, while cilia trap particles.

7. Which structure in the eye is responsible for focusing light onto the retina?
A) Cornea
B) Iris
C) Lens
D) Pupil
Correct Answer: C) Lens
Rationale: The lens refracts and focuses light onto the retina. The cornea
provides initial refraction, the iris controls pupil size, and the pupil regulates
light entry. The lens adjusts shape for near and far vision.
