30 Cards in this Set

  • Front
  • Back
response
cell proliferation and differentiation
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
carbohydrates
fats
protiens
DNA--nucleic acid
DNA
makes protiens or enzymes, provides structures
Biological transmission
through nuclear or biological weapons
what's in body normally
1*10^13^cells
1*10^14^bacteria cells
infection
body invaded by pathogenic organism
test a hypothesis
ask question, define question, need to have a controlled experiment, and repeat the exp.,
procaryote
have no nucleus-bacterium
Jenner
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
