droplet transmission
|
sneezing or coughing
|
|
|
indirect contact
|
transger through non living things
|
|
|
lymphatic vessels
|
carry interstitial fluid (lymph) back to blood--produces about three liters every 24 hours-carry immune cells and foreign substances
|
|
|
lymphoid organs and tissues
|
sites of:lymphocyte development, contact between lymphocytes and foreign substances, lymphocyte responses(adaptive immunity)
|
|
|
Pasteur
|
1800's-proved no spontaneous generation-put broth in flask,heated neck,and bent into s shape, and boiled-no growth of bacteria
|
|
|
systemic
|
not restricted to initial site of infection
|
|
|
rank in size
|
virus
bacteria red blood cell paramecium |
|
|
interferon
|
discovered in 1950's-infected cells w/virus-exposed uninfected cells to liquid that infected cells were growing in-un cells now resistant to viral infection
|
|
|
pathologists
|
study diseases and how they affect the body
|
|
|
memory
|
some responding cells are long lived
|
|
|
surface barriers
|
they protect the body through different ways
|
|
|
recognition
|
foreign molecules by antigen receptors on lymphocytes
|
|
|
vehicle transmission
|
food, air, H20
|
|
|
Fleming
|
developed penecillin--placed petri dish in open and the pen moved towards the microbes
|
|
|
Koch
|
studied relationship between Bacillus anthracis and anthrax in mice-how to prove that a microbe causes disease
|
|
|
four major kinds of carbon molecules

developed vaccine of smallpox because of milking cows--people who got rash on their hand did not get smallpox
|
|
|
disease
|
causes body to enter different state of health
|
|
|
eucaryotes
|
have a nucleus-humans, amebas, fungi, mold
|
|
|
innate
|
nonspecific-no previous exposure needed
|
|
|
adaptive
|
acquired or specific--needs previous exposure-mainly describes the response of lymphocytes to specific pathogens-has memory, produce T-cells, to kill virus
|
|
|
microbes
|
organisms that we can't see
|
|
|
phagocytes
|
neutrophils and macrophages--these cells are capable of ingesting, killing, and digesting foreign material
|
