QCM : Fundamentals of Human Anatomy and Physiology — 10 questions

Question 1

1. What is the primary role of epithelial tissue in the human body?

To provide energy for cells

To contract and produce movement

To support and connect tissues

To cover surfaces and line cavities

Explication

Epithelial tissue mainly functions to cover surfaces and line cavities within the body, serving as a protective barrier and involved in absorption, secretion, and sensation.

Answer

To cover surfaces and line cavities

Question 2

2. Which tissue type is primarily responsible for movement in the human body?

Muscle tissue

Connective tissue

Epithelial tissue

Nervous tissue

Explication

Muscle tissue, including skeletal, cardiac, and smooth muscles, is responsible for movement. Connective tissues support or connect tissues, epithelial tissues line surfaces, and nervous tissue transmits signals.

Answer

Muscle tissue

Question 3

3. Which organ's structural feature significantly increases its surface area to facilitate gas exchange?

The liver's lobules

The lung's alveoli

The kidney's nephrons

The heart's chambers

Explication

The lungs contain alveoli, which are tiny sac-like structures that greatly increase surface area, enhancing the efficiency of gas exchange between air and blood.

Answer

The lung's alveoli

Question 4

4. What is the main function of alveoli in the lungs, as described in the revision sheet?

To increase surface area for gas exchange

To produce mucus for trapping pathogens

To filter blood entering the lungs

To regulate blood flow to the lungs

Explication

Alveoli are tiny sacs with thin walls that increase surface area, facilitating efficient gas exchange through diffusion. They do not produce mucus, filter blood, or regulate blood flow.

Answer

To increase surface area for gas exchange

Question 5

5. Why is the organization of muscle cells important for their function?

Because it controls the muscle's temperature

Because it affects the blood supply to the muscle

Because it determines the color of the muscle

Because it influences the muscle's contractile ability

Explication

The organization of muscle cells is crucial because it directly influences their ability to contract and generate force, enabling movement and other functions.

Answer

Because it influences the muscle's contractile ability

Question 6

6. Which organ is primarily involved in detoxification and bile production?

Liver

Kidney

Spleen

Pancreas

Explication

The liver detoxifies substances, metabolizes nutrients, and produces bile, essential for digestion. The kidneys filter blood, the spleen is involved in immune responses, and the pancreas regulates blood sugar.

Answer

Cells form tissues, tissues form organs, organs form systems

Answer

Thickened alveolar walls in lungs

Answer

Mitochondria

Answer

Through diffusion driven by concentration gradients

Question 7

7. According to the revision sheet, what is the hierarchy of organization in the human body?

Cells form tissues, tissues form organs, organs form systems

Organs form tissues, tissues form cells, cells form systems

Systems form organs, organs form tissues, tissues form cells

Cells form systems, systems form tissues, tissues form organs

Explication

The correct hierarchy starts with cells forming tissues; tissues form organs, and organs work together as systems. This organization allows complex functions to occur efficiently.

Question 8

8. What structural abnormality can impair organ function, as noted in the revision sheet?

Thickened alveolar walls in lungs

Increased flexibility of connective tissue

Thinning of epithelial tissue

Reduced blood vessel diameter in arteries

Explication

Thickened alveolar walls decrease surface area and hinder gas exchange, impairing lung function. Increased flexibility or thinning of tissues typically do not impair function, and reduced artery diameter affects circulation, not directly alveoli.

Question 9

9. Which cellular organelle is primarily responsible for ATP production?

Mitochondria

Nucleus

Endoplasmic reticulum

Golgi apparatus

Explication

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration, which fuels physiological processes. The nucleus controls genetic information, the ER synthesizes proteins, and the Golgi processes materials.

Question 10

10. How do alveoli in the lungs facilitate gas exchange according to the revision sheet?

Through diffusion driven by concentration gradients

By active transport using energy consumption

Via facilitated diffusion through special carriers

By osmosis of gases across cell membranes

Explication

Gas exchange in alveoli occurs via diffusion driven by concentration gradients, allowing oxygen to enter blood and carbon dioxide to be exhaled efficiently.
