75 Multiple Choice Questions | 75 True/False Questions | Total: 150 Questions
SECTION A: MULTIPLE CHOICE QUESTIONS (MCQ)
Instructions: Choose the single best answer for each question.
1. What is the basic structural and functional unit of the human body?
A. Organ
B. Tissue
C. Cell
D. Molecule
Answer: C. Cell
Rationale: The cell is the smallest unit capable of performing all basic life functions. Organs and tissues are
made of many cells working together.
2. Which organ system is responsible for transporting oxygen and nutrients throughout the
body?
A. Digestive system
B. Respiratory system
C. Cardiovascular system
D. Nervous system
Answer: C. Cardiovascular system
Rationale: The cardiovascular system, comprising the heart, blood, and blood vessels, transports oxygen,
nutrients, hormones, and waste products throughout the body.
3. What is the largest organ of the human body?
A. Liver
B. Brain
C. Skin
D. Lungs
Answer: C. Skin
Rationale: The skin (integumentary system) is the largest organ, covering the entire body surface and
performing protective, regulatory, and sensory functions.
4. How many bones are in the adult human skeleton?
A. 186
B. 206
C. 196
D. 216
Answer: B. 206
Rationale: The adult human skeleton contains 206 bones. Infants are born with approximately 270–300
bones, many of which fuse during growth and development.
5. Which chamber of the heart pumps oxygenated blood to the entire body?
A. Right atrium
B. Left atrium
, C. Right ventricle
D. Left ventricle
Answer: D. Left ventricle
Rationale: The left ventricle is the most muscular chamber and pumps oxygenated blood through the aorta to
the systemic circulation.
6. What type of muscle is found in the walls of internal organs such as the stomach and
intestines?
A. Skeletal muscle
B. Cardiac muscle
C. Smooth muscle
D. Striated muscle
Answer: C. Smooth muscle
Rationale: Smooth (visceral) muscle is involuntary and found in the walls of hollow organs, controlling
movements like peristalsis in the digestive tract.
7. Which molecule carries oxygen in red blood cells?
A. Myoglobin
B. Albumin
C. Hemoglobin
D. Fibrinogen
Answer: C. Hemoglobin
Rationale: Hemoglobin is an iron-containing protein in red blood cells that binds oxygen in the lungs and
releases it to tissues throughout the body.
8. What is the scientific term for the windpipe?
A. Larynx
B. Pharynx
C. Bronchus
D. Trachea
Answer: D. Trachea
Rationale: The trachea (windpipe) is the cartilaginous tube that connects the larynx to the bronchi, serving as
the main airway to the lungs.
9. Which gland is known as the 'master gland' of the endocrine system?
A. Thyroid
B. Adrenal
C. Pituitary
D. Pancreas
Answer: C. Pituitary
Rationale: The pituitary gland is called the master gland because it secretes hormones that regulate other
endocrine glands and many body functions.
10. What is the term for the process by which cells divide to produce two identical daughter
cells?
A. Meiosis
B. Mitosis
C. Cytokinesis
D. Apoptosis
Answer: B. Mitosis
, Rationale: Mitosis is the process of somatic cell division resulting in two genetically identical daughter cells,
used for growth and tissue repair.
11. Which blood vessel carries blood away from the heart?
A. Vein
B. Capillary
C. Venule
D. Artery
Answer: D. Artery
Rationale: Arteries carry oxygenated blood away from the heart (except the pulmonary artery), delivering it to
organs and tissues.
12. What is the main function of the kidneys?
A. Produce bile
B. Filter blood and form urine
C. Regulate breathing
D. Produce red blood cells
Answer: B. Filter blood and form urine
Rationale: The kidneys filter approximately 180 liters of blood per day, removing waste products and excess
substances to form urine, maintaining fluid and electrolyte balance.
13. Which part of the brain controls balance and coordination?
A. Cerebrum
B. Hypothalamus
C. Cerebellum
D. Medulla oblongata
Answer: C. Cerebellum
Rationale: The cerebellum coordinates voluntary movements, balance, and fine motor control by integrating
sensory input from the vestibular system and proprioceptors.
14. What type of joint is the knee?
A. Ball-and-socket
B. Hinge
C. Pivot
D. Saddle
Answer: B. Hinge
Rationale: The knee is a hinge joint allowing flexion and extension. Ball-and-socket joints (like the hip) allow
multiaxial movement.
15. Which vitamin is essential for calcium absorption in the intestines?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K
Answer: C. Vitamin D
Rationale: Vitamin D (calcitriol) is essential for calcium absorption in the small intestine. Deficiency leads to
rickets in children and osteomalacia in adults.
16. What is the outer protective layer of the skin called?
A. Dermis
