Immune System

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

• B cells produce antibodies that target specific antigens.

• B cells directly kill infected cells.

• B cells enhance the activity of T cells.

• B cells are responsible for the production of hormones.

What is the purpose of vaccination?

• To provide immediate immunity against all diseases.

• To stimulate the immune system to develop memory against specific pathogens.

• To replace the need for a healthy lifestyle.

• To cure existing infections.

What is the role of the skin in the immune system?

• The skin acts as a physical barrier to prevent pathogen entry.

• The skin produces antibodies to fight infections.

• The skin regulates body temperature to enhance immune response.

• The skin absorbs nutrients to support immune function.

Define innate immunity.

• Innate immunity is the body's first line of defense, providing immediate but non-specific protection against pathogens.

• Innate immunity is a type of immunity that develops after exposure to a specific pathogen.

• Innate immunity is the immunity that is acquired through vaccination.

• Innate immunity is the body's ability to remember past infections and respond more effectively.

What is the function of T cells in the immune response?

• T cells produce antibodies to neutralize pathogens.

• T cells help in killing infected host cells and activating other immune cells.

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

• T cells primarily function in the digestion of foreign particles.

Which White Blood cells are involved in Innate Immunity?

• Eosinophils

• Basophils

• Neutrophils

• All of the above (Eosinophils, Basophils, Neutrophils)

What is an example of Artificial active immunity?

• Vaccination

• Breastfeeding

• Infection recovery

• Antibody injection

What is the function of antibodies?

• Antibodies bind to specific antigens to neutralize pathogens or mark them for destruction.

• Antibodies are responsible for producing hormones in the body.

• Antibodies help in the digestion of food in the stomach.

• Antibodies transport oxygen in the bloodstream.

Which cells are NOT part of Adaptive (specific) Immunity?

• B cells

• T cells

• Phagocytes

• Dendritic cells

What is the difference between active and passive immunity?

• Active immunity is developed through exposure to pathogens or vaccination, while passive immunity is acquired through antibodies from another source.

• Active immunity is temporary and does not provide long-term protection, while passive immunity is permanent.

• Active immunity is only obtained through natural infections, while passive immunity can only be obtained through vaccines.

• Active immunity requires immediate exposure to pathogens, while passive immunity can be developed over time.
