LATEST APHY 101 ANATOMY & PHYSIOLOGY FINAL EXAM QUESTIONS AND
ANSWERS 2026.
1. Which level of structural organization is composed of two or more types of tissues
working together to perform a specific function?
A. Cellular level
B. Organ level
C. Tissue level
D. System level
Correct Answer: B
Explanation: The organ level consists of multiple tissue types functioning together
(e.g., heart). Tissue level involves similar cells, while system level involves multiple
organs.
2. Which organelle is primarily responsible for ATP production in eukaryotic cells?
A. Ribosome
B. Lysosome
C. Mitochondrion
D. Golgi apparatus
Correct Answer: C
Explanation: Mitochondria generate ATP through cellular respiration. Ribosomes
synthesize proteins, lysosomes digest materials, and Golgi apparatus modifies
proteins.
3. A patient has damage to the parietal lobe. Which function is most likely affected?
A. Vision
B. Hearing
C. Sensory perception
D. Balance
Correct Answer: C
Explanation: The parietal lobe processes sensory information such as touch. Vision is
occipital, hearing is temporal, and balance involves the cerebellum.
4. Which type of tissue is responsible for lining body cavities and surfaces?
A. Muscle tissue
B. Nervous tissue
C. Connective tissue
D. Epithelial tissue
Correct Answer: D
Explanation: Epithelial tissue lines surfaces and cavities. Muscle contracts, nervous
transmits signals, and connective supports structures.
,5. What is the primary function of red blood cells?
A. Immune defense
B. Oxygen transport
C. Clot formation
D. Hormone transport
Correct Answer: B
Explanation: Red blood cells carry oxygen via hemoglobin. White blood cells handle
immunity, platelets clot blood.
6. Which part of the nephron is responsible for filtration of blood?
A. Loop of Henle
B. Distal tubule
C. Glomerulus
D. Collecting duct
Correct Answer: C
Explanation: The glomerulus filters blood plasma. Other parts modify filtrate.
7. Which hormone regulates blood glucose levels by decreasing it?
A. Glucagon
B. Insulin
C. Cortisol
D. Epinephrine
Correct Answer: B
Explanation: Insulin lowers blood glucose by promoting uptake. Glucagon raises it.
8. Which structure prevents food from entering the trachea during swallowing?
A. Uvula
B. Epiglottis
C. Larynx
D. Pharynx
Correct Answer: B
Explanation: The epiglottis covers the trachea during swallowing.
9. Which type of muscle is involuntary and striated?
A. Skeletal muscle
B. Cardiac muscle
C. Smooth muscle
D. Voluntary muscle
Correct Answer: B
, Explanation: Cardiac muscle is striated but involuntary. Skeletal is voluntary, smooth
is non-striated.
10. What is the main function of the large intestine?
A. Nutrient absorption
B. Enzyme secretion
C. Water absorption
D. Protein digestion
Correct Answer: C
Explanation: The large intestine absorbs water and forms feces.
11. Which ion is most important for depolarization during an action potential?
A. Potassium
B. Calcium
C. Sodium
D. Chloride
Correct Answer: C
Explanation: Sodium influx causes depolarization. Potassium is involved in
repolarization.
12. Which chamber of the heart pumps oxygenated blood to the body?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Correct Answer: D
Explanation: The left ventricle pumps oxygenated blood into systemic circulation.
13. Which type of joint allows movement in multiple axes?
A. Hinge joint
B. Pivot joint
C. Ball-and-socket joint
D. Saddle joint
Correct Answer: C
Explanation: Ball-and-socket joints allow the greatest range of motion.
14. Which structure in the ear is responsible for hearing?
A. Semicircular canals
B. Cochlea
C. Eustachian tube
, D. Tympanic membrane
Correct Answer: B
Explanation: The cochlea converts sound vibrations into nerve impulses.
15. Which blood vessels carry blood away from the heart?
A. Veins
B. Capillaries
C. Arteries
D. Venules
Correct Answer: C
Explanation: Arteries carry blood away from the heart.
16. Which part of the brain controls voluntary movement?
A. Cerebellum
B. Brainstem
C. Cerebrum
D. Medulla oblongata
Correct Answer: C
Explanation: The cerebrum controls voluntary actions.
17. What is the function of alveoli in the lungs?
A. Filter air
B. Produce mucus
C. Gas exchange
D. Warm air
Correct Answer: C
Explanation: Alveoli are the site of oxygen and carbon dioxide exchange.
18. Which vitamin is essential for calcium absorption?
A. Vitamin A
B. Vitamin B12
C. Vitamin C
D. Vitamin D
Correct Answer: D
Explanation: Vitamin D enhances calcium absorption in the intestines.
19. Which gland is known as the "master gland"?
A. Thyroid
B. Pituitary
C. Adrenal
