- peristalsis
- rythmic contracts
- generally
- fever, fatigue, toxicity, tachycardia, leucopenia, leucocytosis, increase in metabolic rate
- body fluids, interferons, antibodies
- chemical defenses
- contaminate food, fomites, dirty hands, filth, droplet nuclei
- indirect modes
- indirect mode of transmission
- spread through conveyers
- what u see with inflamation
- redness swelling pain and heat
- bodys defence against organisms and infection
- anatomical (mechanical) structural defence, chemical defense, physiological
- droplet sprayyyy
- most common mode of transmission
- body responces cilia normal flora mucous membrane skin
- anatomical (mechanical) structural defence
- droplet nuclei
- particles of dried secretions from mouth and nise that may float in the air for a conciderable amount of time over long distances
- saliva pus sputum nasal tears blood feces urine sweat semen vaginal secretion
- portal of exits
- 3 functions to inflammitory process
- destroy irritation again and remove it and its products, limit the extension of infection, mechanism for repair and replacemnt of tissue
- skin (a)
- first line of defense against organisms
- lysozymes
- found in tears that will destroy the wall of gram positive bacteria
- 4 factors that influence occurance of an infection
- immunity of host, proper portal of entry, virulence of organism, # of organisms
- sweating phagocytosis lymphatic system, peristalsis, fever, inflamation
- physiological defenses
- direct mode of transmission
- spread directly from person to person
- interferons
- protein found in the body that fights viruses
- arthropod vector
- insects
- droplet spray
- infectious microbes are casted off in a fine spray from mouth and nose during sneezing laughing and coughing
- mouth nose urogenital tract skin placenta
- portal of entry
- direct contact, sexual, placental, droplet spray
- direct modes
- mechanical vector
- arthropod that hold pathogen on feet and accidentally transmits to food or body part
- mucouse membrane (a) and cilia
- filters
- biological vector
- arthrod that bited person or animal that is infected, injest some of infectious blood then bites another person and transmits infection
- fever
- slows groth of organisms and increasing phagocytosis
