• It serves as a defense mechanism for the body.

• It filtrates organisms that cause disease.

• It produces certain white blood cells.

A woman is drinking from a river that is used to dump the village's waste. How could this impact the health of individuals and the public?

The immune systems consists of the skin, nose and nose hairs, lymph, lymph nodes, lymphatic vessels, lymphocytes (white blood cells), spleen, and thymus. The specific immune response plays a role in fighting infection when which of the following takes place?

• The skin's protective barrier is broken.

• White blood cells fail to neutralize a pathogen.

• Bacteria are phagocytized by neutrophils.

• Phagocytes are produced in the bone marrow.

Which of the following most accurately describes the function of a vaccine?

• A vaccine benefits a person who has just begun to show signs of an infection by providing them with antibodies from somebody who has already had the illness.

• A vaccine exposes a person to a dead or weakened version of a pathogen, resulting in the production of the appropriate antibody that protects against future infection.

• A vaccine helps control the symptoms of a particular infection while the body’s natural immune response fights to neutralize the pathogens causing the infection.

• A vaccine is used to disinfect an area in which a patient with an infectious illness was treated or recovering to prevent the spread of that illness to other people.
