||||
| 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
🗑
|
||||

| 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
🗑

🗑
|
||||
| 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
