L2 Patho Adaptive (specific) Immunity

What is the primary function of T-cytotoxic cells (Tc)?

• Produce antibodies

• Cause inflammation

• Attack and kill target cells

• Activate the complement system

Which of the following is NOT a characteristic of adaptive immunity?

• Is more specific than innate immunity

• Has memory

• Is faster than innate immunity

• Provides long-term protection

What primarily protects against bacteria and viruses in humoral immunity?

• T-cytotoxic cells

• B cells and circulating antibodies

• Inflammatory mediators

• Pathogens

Which of the following is an example of a noninfectious environmental agent?

• Pathogens

• Transfusions

• Vaccines

• Pollen

What allows for the activation of the classical complement pathway?

• Antibody production

• Memory cells

• T-cytotoxic cells

• Inflammation

What type of immunity involves B cells and circulating antibodies?

• Cell-mediated immunity

• Humoral immunity

• Innate immunity

• Inflammatory response

Which cells are primarily responsible for attacking and killing target cells in cell-mediated immunity?

• B cells

• T-helper cells

• T-cytotoxic cells

• Memory cells

What is a key characteristic of adaptive immunity that distinguishes it from innate immunity?

• It is faster

• It has memory
