Immune System

A person with allergies may develop a rash and swollen eyes when exposed to certain substances. These symptoms are a reaction to

• histamines produced as a result of an immune reaction

• antigens produced as a result of passive immunity

• phagocytosis, resulting in the destruction of body cells

• an increase in the number of platelets

A person with AIDS is likely to develop infectious diseases because the virus that causes AIDS

• destroys cancerous cells

• damages the immune system

• increases the rate of antibody production

• increases the rate of microbe destruction

Which statement best describes an immune response?

• It always produces antibiotics.

• It usually involves the recognition and destruction of pathogens.

• It stimulates asexual reproduction and resistance in pathogens.

• It releases red blood cells that destroy parasites.

In some individuals, the immune system attacks substances such as grass pollen that are usually harmless, resulting in

• an allergic reaction

• a form of cancer

• an insulin imbalance

• a mutation

Certain microbes, foreign tissues, and some cancerous cells can cause immune responses in the human body because all three contain

• antigens

• enzymes

• fats

• cytoplasm

How can you remember antigen goes with pathogen?

• they both have gen in their names

• they both have anti in their names

• they are both antibodies

• they are white blood cells

How can you remember that antibodies are produced by white blood cells in our immune system?

• antibody has a B in it like Blood cell

• antibodies are in our BODY
