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