| Question | Answer |
|---|---|
| the relative ability of the body to defend itself against infection | resistance |
| local physiological response to tissue damage, may result in the loss of function | inflammation |
| heat | calor |
| tumor | swelling |
| dolor | pain |
| rubor | redness |
| systemic physiological response to infections | fever |
| normal body temp is what? degrees celsius and fahrenheit | 37 C 98.6 F |
| chemical defense, process of cells breaking down foreign cells and debris | phagocytosis |
| chemical defense, enzyme found in many body fluids such as tears, breast milk, saliva, and sweat | lysozymes |
| chemical defense, cells of the digestive system that produce hydrohloric acid | gastric juice |
| chemical defense against infection, inhibits spread of viruses in the body | interferon |
| chemical defense, serum proteins that participate in the lysis of foreign cells, inflammation, and phagocytosis | complement system |
| relative power and degree of pathogenicity possessed by the organism to produce disease | virulence |
| the reduction of a microorganism's virulence by diluting or weaking its pathogenicity | attenuation |
| the sum total of body mehcanisms that interpose barriers to the progress of invasion, multiplication of infectious agents, or damage by their toxic products | resistance |
| having little resistance to a disease or pathogen | susceptibility |
| a poisonous substance of plant, animal, bacterial, or fungal origin | toxin |
| type of toxin: generally a protein, soluble in body fluids, sensitive to effects of heat | exotoxin |
| exotoxin: kills host cells or affect their function | cytotoxin |
| exotoxin: interfere with normal nerve impulses | neurotoxin |
| exotoxin: affects host cells lining the gastrointestinal tract | enterotoxin |
| body produces antibodies that provide immunity to exotoxins | antitoxins |
| type of toxin: generally polysaccharides, outer portion of gram negative bacteria, heat resistant | endotoxin |
| bacterial toxin that destroys white blood cells (which are active in phagocytosis) | leukocidins |
| bacterial toxins that cause the lysis of red blood cells (which are instrumental in transporting oxygen to cells of the body) | hemolysins |
| bacterial enzyme that causes blood to clot | coagulase |
| bacterial enzyme that prevents blood from clotting | fibrinolysin |
| bacterial enzyme that breaks down hyaluronic acid, helps microorganisms spread from their initial site of infection | hyaluronidase |
| bacterial toxin that acts on the oils and fats secreted by the sebaceous glands | lipase |
| bacterial enzyme that breaks down the protein collagen fibers in connective tissue | collagenase |
