Immune system Quiz

What are antibodies and how do they function in the immune system?

• Antibodies are carbohydrates that bind to specific antigens and mark them for destruction by other immune cells.

• Antibodies are enzymes that break down antigens and eliminate them from the body.

• Antibodies are proteins that bind to specific antigens and mark them for destruction by other immune cells.

• Antibodies are lipids that coat antigens and prevent them from entering the body.

Explain the difference between antigens and antibodies.

• Antigens trigger the immune response, while antibodies cause infections.

• Antigens are produced by the body, while antibodies come from outside sources.

• Antigens and antibodies are the same thing.

• Antigens trigger the immune response, while antibodies neutralize antigens.

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

• Memory cells are responsible for initiating the immune response

• Memory cells produce antibodies to fight off pathogens

• Memory cells have no role in the immune system

• Memory cells recognize and respond to previously encountered pathogens.

Explain how vaccines work to prevent infections.

• Vaccines contain live viruses that attack the immune system

• Vaccines work by weakening the immune system's response to pathogens

• Vaccines have no effect on the immune system's ability to fight infections

• Vaccines introduce weakened or inactive pathogens to trigger the immune system to produce antibodies.

What are the different types of vaccines and how are they produced?

• Vaccines are made by extracting the virus or bacteria from infected individuals

• Vaccines are produced by mixing different chemicals together

• There is only one type of vaccine and it is produced by injecting the virus or bacteria directly into the body

• Made from dead or weakened form of the virus or bacteria, or by using specific parts of the pathogen to stimulate an immune response.

Discuss the concept of herd immunity and its importance in immunization.

• Herd immunity is the protection of a population from a disease when a high percentage of the community is immune, either through vaccination or previous infections.

• Herd immunity is the spread of disease within a population due to lack of immunity

• Herd immunity is only achieved through natural infections, not vaccinations

• Herd immunity is not important in immunization efforts

Explain the process of immunization and its impact on public health.

• Immunization causes more harm than good

• Immunization helps prevent the spread of diseases and protects public health.

• Immunization only works for a few people

• Immunization has no impact on public health

What are the potential risks and benefits of immunization?

• The potential risks include weight loss and the potential benefits include better hair growth.

• The potential risks include allergic reactions and the potential benefits include protection against serious diseases.

• The potential risks include longer lifespan and the potential benefits include increased strength.

• The potential risks include increased intelligence and the potential benefits include improved eyesight.
