The following activity is for the "key terms" in chapter 4 of your textbook.

Abscess a localized collection of pus
Adhesion parts of tissue that cling to the surface of adjoining organs as normal fibrous scar tissue develops in an operative site, resulting in a fibrous band
Antibody immunoglobulins that develop in response to an antigen; also called immune bodies; proteins that the body produces to read to and render the antigen harmless
Antigen a cell marker that induces a state of sensitivity after coming in contact with an antibody; any substance that causes the body some type of harm, thus setting off this specific reaction
Bacteria a one celled microorganism that may be aerobic or anaerobic and free living, saprophytic, parasitic, or pathogenic
Cellulitis inflammation of connective tissue
Chemotaxis the movement of cells or organisms in response to chemicals
Culture and sensitivity a test to identify a pathogen and the type of treatment needed
Debridement a process of washing or cutting away necrotic tissue and foreign material
Dehiscence separation of tissue margins
Diapedesis passage of blood, or its formed elements through the intact walls of blood vessels
Empyema an accumulation of pus in the body cavity
Exudate fluid that has seeped out of tissue or capillaries because of injury or inflammation
Fistula a tract that connects two organs or cavities to each other or to the surface of the skin
Fungi forms of yeast and molds; microscopic plant like organisms
Helminths intestinal parasites; also called worms; nematodes, cestodes, and trematodes
Histamine a substance that causes local arterioles, venules, and capillaries to dilate resulting in an increase in blood flow to the area; released in response to injury or irritation
Hyperemia increased blood flow in response to a release of histamine
Induration hardened tissue
Infection invasion of microorganisms into the tissue causing cell or tissue injury thus leading to the inflammatory response
Inflammation a pathologic process of cytologic and chemical reactions that occur in the blood vessels and tissues in response to an injury or irritation; a protective immune response that is triggered by any type of injury or irritant
Keloid excessive collagen formation often resulting in a hard raised scar
Lesion an discontinuity of tissue
Leukocytosis an increase in white cell count
Macrophage a monocyte that leaves the bloodstream and moves into the tissue and becomes phagocytic
Malaise general ill feeling
Mast cells also called tissue histiocytes; found in all tissues of the body; play a major role in the inflammatory process
Opportunistic normal flora bacteria that take the “opportunity” to cause infection in the host
Primary union also called healing the first intention; involves approximating the edges of the wound
Protozoa a parasite of the phylum Protozoa; a single celled microscopic member of the animal kingdom
Purulent loaded with dead and dying neutrophils, tissue debris, and pyogenic (pus forming) bacteria
Pus white or yellow exudates due to death of numerous neutrophils mixed with exudates or blood fluid
Pyogenic pus forming
Rickettsiae microscopic organisms that are intermediate between bacteria and viruses. They live in the host and are spread by lice, fleas, ticks, and mites
Scar skin lesion resulting from fibrous connective tissue repair
Secondary union also called healing by secondary intention; the same process as primary union but involving a larger degree of tissue damage and more inflammation to resolve
Septicemia a systemic disease caused by the spread of microorganisms in the blood; also called blood poisoning
Sinus a tract or opening to the surface of the body formed by a large ruptured abscess
Tachycardia a rapid heart rate; usually a rate above 100 beats per minute
Trauma a physical or mental injury
Ulcer a crater like lesion in the skin or mucous membranes
Virulent difficult to kill; able to produce disease
Virus(es) a large group of infectious agents; they are much smaller than bacteria and must be viewed with an electron microscope. They can pass through fine filters that would retain most bacteria
