Immune responses that target specific a pathogen is known as

• Passive

• Active

• Adaptive

• Innate

Immune responses that are not specific to the pathogen

• Passive

• Active

• Adaptive

• Innate

Cell responsible for engulfing and digesting foreign pathogens (nonspecific)

• Phagocyte

• Natural Killer Cells

• B Cell

• T Cell

A nonspecific defensive response of the body to tissue injury characterized by dilation of blood vessels and swelling.

• immunity

• interferon

• immunization

• inflammation

The innate immune system is...

• Always working and doesn't require any special preparation

• Needs to be "primed" before it can work to its full effectiveness

• Very specific and only defends against a specific pathogen

• Not very effective at preventing intruders

Which of the following is NOT an example of an innate immune response?

• macrophages engulfing pathogens

• fever

• production of antibodies by b cells

• inflammation

A protein marker on the cell surface that acts as an identifier for other cells (a name tag)

• antigen

• antibody

• histamine

• cytokine

a protein produced by immune cells to attach to and target specific pathogens, they bind to antigens

• antigen

• antibody

• histamine

• cytokine

Which cells produce antibodies?

• Mast cells

• Macrophages

• Natural Killer Cells

• B Cells

Bacteria, fungi, viruses, and protists that can cause an infection

• antibody

• antigen

• allergy
