Toxin - Poisonous substance (acting as Ag) produced by ______

Immune system - protects the human ______

The study of disease is called ______.

The study of the cause of a disease is called ______.

The development of disease is called ______.

A ______ disease is spread from one host to another.

A ______ disease is not spread from one host to another.

A ______ infection is limited to a small area of the body.

A ______ infection is an infection throughout the body.

A ______ infection is caused by opportunistic pathogens after a primary infection.

Transmission via airborne droplets more than 1 meter is called ______ transmission.

The ______ are leukocytes with granules in their cytoplasm that are visible with a light microscope.

The ______ release histamine and are involved in allergic responses.

The ______ are toxic against parasites and worms.

The ______ are phagocytic and work in the early stages of infection as first responders.

The ______ travel in blood and will mature into macrophages in tissues where they become phagocytic cells.

The ______ is the ingestion of microbes or other substance by a phagocyte.

The ______ is the release of chemical signals (cytokines) by a pathogen that attract phagocytes.

A ______ is a pathogen that is too big to be engulfed by a phagocyte.

The ______ is a waxy lipid that inhibits phagocytosis.

Phagocytes are able to ______ bacteria and multiply inside them.

______ is the process of complement proteins coating the surface of a pathogen to promote attraction and attachment of phagocytes.

Complement proteins bind mast cells, which release ______, increasing blood vessel permeability and attracting phagocytes.

______ is the study of host defenses against foreign substances (antigens).

______ immunity fights invaders and threats outside of the cell (extracellular antigens).

______ T cells activate cytotoxic T cells involved in cell-mediated immunity and certain B cells to produce antibodies.

______ T cells, also known as "killer" T cells, destroy target cells on contact.

______ T cells suppress or turn off the immune response when it is not needed.

______ T cells produce a delayed and exaggerated immune response that can occur from days to years later.

______ T cells promote a relatively long-lasting immune response.
