Exam 32: The Immune System

In the case of AIDS,death is more likely to result from other infections that the immune system CANNOT control than from HIV itself.

The ability to resist specific pathogens using a coordinated combination of specialized cells and molecules is the primary function of the ________.

The immune system is considered to consist of two subdivisions,a nonspecific component consisting primarily of barriers and phagocytes known as the innate response and a highly specific component consisting primarily of antibody and cell-mediated strategies known as the ________ response.

A fever is the product of an out-of-control immune response to a parasite.

When pathogens overcome the barrier defenses and enter the body they are quickly met by macrophages and neutrophils,two types of cells that constitute a large fraction of the nonspecific or ________ response.

The blood of vertebrates contains a large number of cells that participate in both the innate and adaptive immune responses.To what group of blood components do these cells belong?

The pathology of a virus is very different from that of a bacterium or fungal cell,and unique innate strategies exist for combating each.During a viral infection,infected cells may

Phagocytosis is one of the primary strategies of the innate immune response,which is hardly surprising considering that approximately 70 percent of the circulating white blood cells are the phagocytic ________.

Virally infected cells release interferon in order to protect neighboring cells from infection.

One aspect of inflammation is swelling;it develops when capillary permeability changes and ________ moves from the vascular system into the interstitial spaces around the cells.

One of the most common examples of innate immunity component is the
