Match the defense cell with the correct characteristic: Macrophages.

A common antigen presenting cell (APC)

Identify the part of the immune system labelled as "B."

Adaptive defenses

When collagen fibers are laid down to wall off a sac of pus, what structure is formed?

An abscess

Match the following term with its correct description: Leukocytosis.

An increase in the number of white blood cells that are in circulation

Match the following inflammatory response term with the correct causative activity: Edema.

Caused by excess tissue fluid in the injured area; helps to dilute harmful substances and brings in excess oxygen

Identify the part of the immune system labelled as "F."

Cellular immunity

Match the following term associated with the correct inflammatory process: Inflammatory chemicals attract neutrophils to the injured areas.

Chemotaxis

Which of the following is not a surface barrier to pathogen influx?

Complement cascade

Match the following cell of the immune system with its function: Macrophages.

Derived from circulating monocytes

Match the following term associated with the correct inflammatory process: Neutrophils squeeze through walls of capillaries into the tissues.

Diapedesis

Identify the part of the immune system labelled as "E."

Humoral immunity

Match the following inflammatory response term with the correct causative activity: Hyperemia.

Increased blood flow due to vasodilation of blood vessels entering the injured area

Identify the part of the immune system labelled as "A."

Innate defenses

Identify the part of the immune system labelled as "D."

Internal defenses

Which of the following minerals needed for bacterial reproduction do both the liver and spleen sequester during a fever?

Iron and zinc

Saliva and lacrimal fluids contain this enzyme that destroys bacteria.

Lysozyme

Identify the cell shown.

Macrophage

Which of the following is a nonspecific barrier defense?

Mucous membranes

Which nonspecific defense cells specialize in attacking cancer cells and virus-infected cells?

Natural killer cells

Which of the following is not one of the cardinal signs of inflammation?

Opsonization

Match the following cell of the immune system with its function: Neutrophils.

Phagocytes; will migrate to the site of an infection within a few hours

These molecules are secreted by leukocytes and macrophages and result in a fever.

Pyrogens

Match the following inflammatory response term with the correct causative activity: Exudate.

Seeps from the capillaries and contains clotting factors and antibodies

Identify the part of the immune system labelled as "C."

Surface barriers

Match the following inflammatory response term with the correct causative activity: Chemotaxis.

The process by which white blood cells are attracted to the site of an injury

Match the following term with its correct description: Opsonization.

This process encourages phagocytosis.
