Anatomy 12.2 - Nonspecific Defenses

Types of white blood cells that engulf and consume bacteria, foreign material and debris.

• phagocytosis

• phagocytes

• pyrogens

• prostaglandins

the process by which a cell engulfs and destroys foreign matter.

• phagocytosis

• phagocyte

• pyrogens

• prostaglandins

Left over debris from phagocytosis is pushed out of the cell in a process called

• endocytosis

• exocytosis

• alternative pathway

• classical pathway

The most common type of leukocytes or white blood cells, slips out of the blood capillaries (tiny vessels) and into surrounding tissue where they destroy bacteria and cellular debris.

• exocytosis

• pyrogens

• neutrophils

• mast cells

Leukocytes that develop into phagocytozing macrophages when they migrate out of the lymphatic circulation into surrounding tissue.

• mast cells

• monocytes

• opsonins

• neutrophils

A set of over 30 proteins (but 11 work in this part) that circulate blood plasma through the body and work together to destroy foreign substances. It balances out the specific (T-cells & B-cells) and nonspecific defenses of the body.

• compliment system

• inflammatory response

• classical pathway

• opsonins

A circulating protein recognizes an antibody bound to a foreign material in tissues or blood. This activates the compliment proteins an kicks off a cascade of compliment protein activation.

• compliment system

• alterative pathway

• classical pathway

• prostaglandins

One of the two ways the compliment system can be activated. This is triggered when a C3b compliment protein binds to a foreign material. This occurs when the protein recognizes foreign material like bacterial cell walls.

• alternative pathway

• classical pathway

• complement proteins

• compliment system

Proteins that make cells more attractive to phagocytes are called

• mast cells

• phagocytes

• prostaglandins

• opsonins

Connective tissue cells with granules (particles) that contain histamine, a compound which when released into surrounding fluid, activates an inflammatory response.

• opsonin

• prostaglandin

• pyrogen

• mast cell
