hypoethsized that specialized cells in the body detroy invading microorganisms TERM 2
DEFINITION 2 Mitchenkoff TERM 3
DEFINITION 3 sterile TERM 4
DEFINITION 4 Host defences involving anatomical barriers senor systems that recoginize patterns associated with microbes or tissue damage phagocytotic cells and an immune response TERM 5
DEFINITION 5 non-specific defense
detecting molecules associated with invading microbes or tissue dammage TERM 7
DEFINITION 7
DEFINITION 8 develops throughout life and increases the host ability to defend itself. TERM 9
DEFINITION 9 a substance that causes an immune response TERM 10
DEFINITION 10 Y- shaped proteins-bind to antigens-targeting them for destruction by host defences
provide physical separation-bathed in antimicrobial secretions TERM 17
DEFINITION 17
DEFINITION 18 cells send chemical signals to alert the other compnents of the host defenses TERM 19
DEFINITION 19 cytoplasm -- allowing the recosignize whent hey have been invaded by a microbe. TERM 20
DEFINITION 20 proteins present in the blood and tissue fluid-they can complement the adaptive immune defences
when it is set off by certains stimulie creating a chain of rections for the removal and destrcution of certain microbes TERM 22
DEFINITION 22 Inflamatory response TERM 23
DEFINITION 23
DEFINITION 24 swellingheatrednesspain TERM 25
DEFINITION 25 cells that line the local blood vessels under go changes and allows the complement systems proteins to leak out of tissues - phagocytistic cells
skinmucus membranesanitomical barriersnormal microbiota TERM 32
DEFINITION 32 line the digestive, respiratory, genitourinary tract.-mucus prevents microbes from coming in, washes them from surface.-mechanisms to move microbes towards areas where they can be eliminated TERM 33
DEFINITION 33 contraction of the intestional tract which propels foods and microbes away to remove microbes. TERM 34
DEFINITION 34 in respitaorary tractmove in up beat motion to move debris away from lungs towards throat to be swallod TERM 35
DEFINITION 35 enzyme that degrades peptidoglycan-tears, saliva, mucus.-in the body, phagocytistic cells, tissues, fluid that bathes tissues
break down Hydrogen peroide to produce reactive oxygen species-salive and milk, body tissues, phagocytes.-catlase enzyme/ can break it down. TERM 37
DEFINITION 37 iron binding protein in saliva, mucus and milk.-withholding iron to prevent microbial growth TERM 38
DEFINITION 38 same as lactoferrin but in the blood and tissue fluid TERM 39
DEFINITION 39 -antimicrobial peptides produces by nuetrophils and eptheilial cells.-insert into bacterial membranes forming pores. that damge cell. TERM 40
DEFINITION 40 population of microbes that grow on the bodies surface of healthy humans-these are not apart of immune system
learns to distinguish harmless bacteria from pathogens TERM 47
DEFINITION 47 the formation of RBC TERM 48
DEFINITION 48 all RBC and important cells of the bodys defense originate from this TERM 49
DEFINITION 49 -various types of blood cells TERM 50
DEFINITION 50 group of proteins which make stem cells divide into many different things
DEFINITION 52 contain cytoplasmic granules filled with biologically active chemicles TERM 53
DEFINITION 53 -nuetrophil-basophil-eosinphil TERM 54
DEFINITION 54
DEFINITION 55 involved in allergic reactions and inflamtion-stain dark with methylene blue-contain histamine that increase capillary inflammation
macrophagesdendric cells TERM 62
DEFINITION 62 -functions as scouts-engulf material in the tissues and then bring it to the cells of the adaptive immune system for a inspection-most come from monocytes TERM 63
DEFINITION 63 -responsible for adaptive immunity- B cells and T cells- NK cells TERM 64
DEFINITION 64
DEFINITION 65 lymphocytes-lack specific immunity for antigen
DEFINITION 67
DEFINITION 68 molecule that can bind to a specific receptor TERM 69
DEFINITION 69 "voices"of the cell-produced by one cells and diffuses to another by binding to cytokine receptor of that cell.-causes cell death TERM 70
DEFINITION 70 -important to chemotaxis-have receptors from cytokines
pathogen -associated molecular patterns (PAMP) TERM 77
DEFINITION 77 detect generic microbe associated patterns as a sign of microbial invasion TERM 78
DEFINITION 78
DEFINITION 79 molecules that indicate host cell damage TERM 80
DEFINITION 80 in the membrane of look out cells such as macrophages, dendritic cells, and cells that line the sterile body sites.recognize a distinct compound associated with microbes-allows cells to see PAMPs in the EC enviorment- endosomal or phagosomal material, facing the lumen of organelle which let macrophages characterize materials they ingested.
a signal is transmitted to cells nuclues causing certain genes to be expressed.-ex, inflammatory response, antiviral response TERM 82
DEFINITION 82 cytoplasmic proteins that detect bacterial components so cell known when own boarders have been breached and also a sign of cell damage. TERM 83
DEFINITION 83 unleash a series of events that lead to outcomes that effect the host, may causing its own life. TERM 84
DEFINITION 84 in macrophages NLRs join with other proteins in cytoplasm to form this-actives a potent pro inflammatory cytokine which inniates an inflammatory response. TERM 85
DEFINITION 85 -cytoplasmic proteins that detect viral RNA-infected cell to detect an invader (receptors for RNA)
known by adding a lowercase letter to each nameC3 split= C3a and C3b TERM 92
DEFINITION 92
DEFINITION 93 the complement system can be activated by the 3 different pathways that converge once it is formed. TERM 94
DEFINITION 94 is triggered when C3b binds to foreign cell surfaces-the binding C3b allows other complement proteins to attach forming C3 covertase-3Cb is always present bc C3 is unstable and splits into a and b TERM 95
DEFINITION 95 C3b
-involves pattern recognition molecules called mannose binding lectins (MBLs)-these bind to mutiple mannose molecules that characterize microbial cells- once MLB attatches to a surface it can complement system components to from C3 convertase TERM 97
DEFINITION 97 Mannose binding lectin (milk) TERM 98
DEFINITION 98 -requires antibody-when antibodies bind to antigen it forms antigen-antibody complex which is also an immune complex- which interacts with the same complement system TERM 99
DEFINITION 99 antibodies TERM 100
DEFINITION 100 opsonizationinflammatory responselysis of foreign cells
