Immune System

What is the function of T-cells in the immune system?

• T-cells help to produce antibodies against pathogens.

• T-cells are responsible for the production of red blood cells.

• T-cells play a central role in cell-mediated immunity, helping to destroy infected cells.

• T-cells are involved in the clotting process of blood.

What role do white blood cells play in the immune system?

• They produce antibodies that neutralize toxins.

• They are crucial for the immune response; they identify and attack pathogens.

• They transport oxygen throughout the body.

• They help in the digestion of food.

How do vaccines work?

• Vaccines cause the disease to develop immunity.

• Vaccines stimulate the immune system to produce an immune response without causing the disease, often by introducing a harmless form of the pathogen.

• Vaccines are only effective if administered after infection.

• Vaccines work by directly killing the pathogens in the body.

What is a pathogen?

• A type of medication used to treat infections.

• An organism that can cause disease, such as bacteria, viruses, fungi, or parasites.

• A method of preventing disease transmission.

• A type of immune response in the body.

What is the role of memory cells in the immune system?

• Memory cells are responsible for producing antibodies during an infection.

• Memory cells are long-lived immune cells that remember past infections and enable a faster response upon re-exposure to the same pathogen.

• Memory cells are involved in the initial detection of pathogens.

• Memory cells are short-lived cells that help in the immediate response to infections.

What is an autoimmune disease?

• A disease caused by a bacterial infection that affects the immune system.

• A condition where the immune system mistakenly attacks the body's own cells, tissues, or organs.

• A genetic disorder that affects the body's ability to produce insulin.

• A type of cancer that originates in the immune system.

What is an antigen?

• A type of white blood cell that fights infections.

• A substance that triggers an immune response, often found on the surface of pathogens.

• A vaccine that prevents diseases.

• A chemical that causes allergic reactions.

What is an antibody?

• A type of white blood cell that fights infections.

• A Y-shaped protein produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

• A hormone that regulates blood sugar levels.

• A molecule that carries oxygen in the blood.

What are the primary components of the immune system?

• Red blood cells, platelets, and plasma

• White blood cells, antibodies, the lymphatic system, and organs like the spleen and thymus

• Skin, hair, and nails

• Hormones and enzymes produced by the pancreas

What is the difference between active and passive immunity?

• Active immunity is when antibodies are transferred from another source.

• Passive immunity occurs when the body produces its own antibodies in response to an antigen.

• Active immunity occurs when the body produces its own antibodies in response to an antigen, while passive immunity is when antibodies are transferred from another source.

• Passive immunity is a long-lasting immunity that develops after vaccination.
