Unit 1: Cell and Basic Physiology (Questions 1-4, 8)
1. What is the primary function of the cell membrane?
Answer: Regulates movement of substances in and out of the cell
Explanation: The phospholipid bilayer controls selective permeability,
maintaining cellular homeostasis.
2. Which organelle is responsible for ATP production?
Answer: Mitochondria
Explanation: Mitochondria generate ATP through cellular respiration.
3. What type of tissue forms the lining of blood vessels?
Answer: Simple squamous epithelium
Explanation: Thin cells allow rapid diffusion and filtration.
4. Which of the following is not a primary tissue type?
Answer: Skeletal
Explanation: The four primary tissue types are epithelial, connective, muscle,
and nervous.
8. What is the normal pH of human blood?
, Answer: 7.35–7.45
Explanation: Slightly alkaline range required for homeostasis.
Unit 1: Cardiovascular, Blood, and Lymphatic Systems (Questions 5-7,
9)
5. Which blood cells are responsible for oxygen transport?
Answer: Red blood cells (erythrocytes)
Explanation: Hemoglobin binds oxygen for transport.
6. What is the main function of white blood cells?
Answer: Immune defense
Explanation: Leukocytes fight infection and foreign invaders.
7. What is the primary function of the sinoatrial (SA) node?
Answer: Initiate the heartbeat (pacemaker)
Explanation: The SA node generates electrical impulses that set the rhythm
of the heartbeat.
9. Which chamber of the heart pumps oxygenated blood to the body?
Answer: Left ventricle
Explanation: It generates high pressure for systemic circulation.
Unit 2: Respiratory System (Questions 10-15)
10. What is the function of the respiratory system?
Answer: Gas exchange (oxygen in, carbon dioxide out)
Explanation: Oxygenation of blood and removal of CO₂.
11. Where does gas exchange occur in the lungs?
Answer: Alveoli
Explanation: Thin walls allow diffusion of gases.
, 12. What structure prevents food from entering the trachea?
Answer: Epiglottis
Explanation: Closes the airway during swallowing.
13. Which of the following is the functional unit of the kidney?
Answer: Nephron
Explanation: It is responsible for filtration, reabsorption, and secretion.
14. Why is the right kidney lower than the left?
Answer: Because of the liver
15. The diaphragm contracts during:
Answer: Inhalation
Explanation: Contraction of the diaphragm flattens it, increasing thoracic
volume to allow air into the lungs.
Unit 2: Digestive and Endocrine Systems (Questions 16-21)
16. Which organ secretes glucagon, which breaks down glycogen?
Answer: Pancreas
Explanation: Alpha cells in the pancreas secrete glucagon.
17. Which hormone lowers blood glucose levels?
Answer: Insulin
Explanation: Insulin promotes glucose uptake by cells, reducing blood sugar
levels.
18. Where does most nutrient absorption occur?
Answer: Small intestine
Explanation: It absorbs carbohydrates, proteins, fats, vitamins, and minerals.
19. Which organ produces bile?
, Answer: Liver
Explanation: The gallbladder stores bile, but it’s produced by the liver.
20. What is the main function of the large intestine?
Answer: Absorption of water and electrolytes
Explanation: It reabsorbs water to form solid feces.
21. What is peristalsis?
Answer: Wave-like muscle contractions in digestive tract
Explanation: It moves food forward through the digestive system.
Unit 3: Reproduction and Development (Questions 22-45, 48)
22. What is the primary purpose of the reproductive system?
Answer: Process by which genetic material is passed from one
generation to the next
Explanation: Reproduction ensures the continuation of the species.
23. Which structure supports the uterus?
Answer: Broad ligament
Explanation: It helps maintain the uterus’ position within the pelvic cavity.
24. What are the primary female reproductive organs?
Answer: Ovaries
Explanation: They produce ova and secrete estrogen and progesterone.
25. What are the three layers of the uterus (from inner to outer)?
Answer: Endometrium, Myometrium, Perimetrium
Explanation: The endometrium is the inner layer, myometrium the middle,
and perimetrium the outermost.
26. Describe the shape of the uterus.
