Immune System Quiz

What is the role of skin in the body's nonspecific defenses?

• Skin produces antibodies that attack pathogens.

• Skin acts as a nearly impenetrable barrier to invading pathogens.

• Skin sends out T cells to destroy pathogens.

• Skin secretes hormones that kill pathogens.

Which type of cell is responsible for attacking and killing infected cells and remembering the pathogens for future attacks?

• Macrophages

• Memory T cell

• Helper T cell

• Inflammatory response cells

What is the function of interferon in the immune response?

• It increases body temperature to slow the growth of bacteria and speed up the production of immune cells.

• It stimulates healthy cells to produce proteins that interfere with virus reproduction.

• It consumes pathogens and infected cells.

• It causes blood vessels to dilate, increasing blood flow to the infection site.

What is the primary function of a vaccine?

• To produce plasma cells and memory B cells.

• To stimulate the production of interferon.

• To provide immunity to diseases by introducing memory T cells and memory B cells.

• To fight bacterial and fungal infections.

How do antibiotics work to fight infections?

• They increase body temperature to kill pathogens.

• They stimulate the production of T cells.

• They fight infections by producing antibodies.

• They work by preventing bacteria and fungi from building cell walls or making important proteins.
