20 - 10.2 The Immune Response Quiz

Anything that triggers an immune response is a/n

• lymph cell

• antigen

• antibody

• neutrop

Answer explanation

An antigen is any substance that triggers an immune response. It can be a pathogen, toxin, or foreign molecule. Lymph cells, antibodies, and neutrophils are components of the immune system but do not trigger responses themselves.

Cells that ingest pathogens are

• plasma cells

• phagocytic cells

• helper T cells

• antibodies

Answer explanation

Phagocytic cells are specialized immune cells that ingest and destroy pathogens. Unlike plasma cells, helper T cells, and antibodies, which have different roles in the immune response, phagocytic cells directly engulf harmful microorganisms.

What is the body's first line of defense against disease?

• skin

• blood

• antibodies

• enzymes

Answer explanation

The skin acts as the body's first line of defense against disease by providing a physical barrier that prevents pathogens from entering the body. It protects internal organs and tissues from infection.

How are vaccinations able to help us develop immunity?

• Exposure to disease creates antibodies which make us immune

• Exposure to antibodies which makes us the disease immune to us

• Exposure to immunity's which make us antibodies to the disease

Answer explanation

Vaccinations expose the immune system to a harmless part of the disease, prompting it to create antibodies. This process helps the body recognize and fight the actual disease in the future, making us immune.

Which pathogen can be cured by antivirals?

• Virus

• Bacteria

• Protist

• Fungi

Answer explanation

Antivirals are specifically designed to treat viral infections, making 'Virus' the correct choice. Bacteria, protists, and fungi are treated with antibiotics or antifungals, not antivirals.

Which pathogen can be cured by antibiotics?

• Virus

• Bacteria

• Protist

• Fungi

Answer explanation

Antibiotics are effective against bacteria, making them the correct choice. They do not work on viruses, protists, or fungi, which require different treatments.

What type of immunity develops when you receive antibodies to a disease?

• Innate

• Developed

• Adaptive

• Passive

Answer explanation

Passive immunity develops when you receive antibodies from another source, such as through maternal transfer or an injection. This type of immunity provides immediate protection but is temporary, unlike adaptive immunity which develops over time.

The complex system of cells and proteins that defend the body against infection is called...

• The endocrine system

• The respiratory system

• the immune system

• the circulatory system

Answer explanation

The immune system is the complex network of cells and proteins that protects the body from infections. It includes various components like white blood cells and antibodies, making it essential for defending against pathogens.

If you have immunity to a disease:

• It can not enter your body

• Your body can fight the disease off before it makes you sick.

• The germs change as soon as they enter your body.

• You will be able to recover very quickly.

Answer explanation

Having immunity means your body can recognize and combat the disease effectively, preventing it from making you sick. This is why the correct answer is that your body can fight the disease off before it makes you sick.

What do antibodies do?

• Attach themselves to germs to flag them for destruction.

• Engulf and digest germs.

• Make your cells impenetrable to germs.

• Carry genes from your bloodstream to the outside of your body.

Answer explanation

Antibodies attach themselves to germs, marking them for destruction by other immune cells. This process helps the immune system identify and eliminate pathogens effectively.
