AP Immune system warm up

All of these are part of the innate immune response except: 

• B cells
• mast cells
• natural killer cells
• macrophages

All of the following are aspects of inflammation except: 

• constriction of blood vessels
• phagocytes and neutrophils produce cytokines that signal the brain to produce a fever
• increase in permeability of blood vessels
• pain

This protein increases the blood vessels permeability to WBCs and other substances involved in the immune response.

• histamine
• complement
• lysozyme
• defensin

A key part of the humoral immune response is

• the attack of cytotoxic T cells on infected host cells.

• the production of antibodies by plasma cells.

• perforation of infected host cells by perforin.

• the attack of phagocytes on living pathogens.

substances that cause a response from the immune system are called _____________________

• Antigens

• Active Immunity

• Antibodies

• Antibiotics

What term describes globular proteins produced by B cells that are designed to mark antigens to be destroyed? These proteins are specific to each antigen.

• Antigens

• Active Immunity

• Antibodies

• Antibiotics

Which of the following is NOT a first line of defense of the non-specific (innate) immune system? These mechanisms prevent pathogens from entering the body.

• skin

• mucous membranes

• fever

• stomach acid

Which of the following is a non-specific/innate response?

• Fever
• B and T lymphocytes
• antibodies
• all are innate responses

Which cell recognizes and phagocytizes recognizes pathogens and displays the pathogens to the other cells?

• Macrophage

• complement

• B Cells

• inflammatory

All of the following are non-specific barrier defenses EXCEPT:

• skin
• T cells
• lysozyme in saliva
• mucous secretions
