1.

What is the main function of the immune system?

a)

To make coffee

b)

To predict the weather

c)

To count calories

d)

To protect the body from harmful pathogens

2.

What are the two main types of immunity?

a)

natural immunity and artificial immunity

b)

innate immunity and humoral immunity

c)

passive immunity and acquired immunity

d)

innate immunity and adaptive immunity

3.

What are antibodies and how do they work?

a)

Antibodies are small molecules that neutralize toxins in the body.

b)

Antibodies are carbohydrates that inhibit the immune response.

c)

Antibodies are proteins produced by the immune system that recognize and bind to specific antigens, marking them for destruction.

d)

Antibodies are produced by the digestive system to aid in nutrient absorption.

4.

Explain the difference between innate and adaptive immunity.

a)

Innate immunity is non-specific and the body's first line of defense, while adaptive immunity is specific and develops over time.

b)

Innate immunity does not involve memory cells, while adaptive immunity does.

c)

Innate immunity is acquired through exposure, while adaptive immunity is present at birth.

d)

Innate immunity is specific to pathogens, while adaptive immunity is non-specific.

5.

What is the role of white blood cells in the immune system?

a)

White blood cells are responsible for transporting oxygen in the body.

b)

White blood cells help with digestion by breaking down food particles.

c)

White blood cells produce insulin to regulate blood sugar levels.

d)

White blood cells defend the body against infections and foreign invaders by identifying and destroying pathogens.

6.

How do vaccines help the immune system?

a)

Vaccines only work for a short period and then stop providing immunity

b)

Vaccines introduce a part of a pathogen to trigger the immune response and produce antibodies, providing immunity.

c)

Vaccines weaken the immune system by introducing harmful pathogens

d)

Vaccines have no impact on the immune system

7.

What is the purpose of inflammation in the immune response?

a)

Inflammation aims to weaken the immune system

b)

Inflammation is meant to spread pathogens throughout the body

c)

The purpose of inflammation in the immune response is to localize and eliminate pathogens, clear out damaged tissues, and initiate the healing process.

d)

Inflammation is designed to accelerate tissue damage

8.

Describe the process of phagocytosis in the immune system.

a)

Phagocytosis is the process by which phagocytes engulf and digest foreign particles or pathogens in the immune system.

b)

Phagocytosis is a process that occurs in the digestive system

c)

Phagocytosis involves the production of antibodies

d)

Phagocytosis is the process of releasing toxins into the body

9.

What are some common diseases caused by a weakened immune system?

a)

Influenza, pneumonia, tuberculosis, certain types of cancer

b)

Common cold, chickenpox, strep throat

10.

How does stress affect the immune system?

a)

Stress enhances the immune system by reducing inflammation

b)

Stress has no impact on the immune system

c)

Stress boosts the immune system by increasing the production of white blood cells

d)

Stress weakens the immune system by releasing stress hormones like cortisol, which can suppress its effectiveness.
