Which leads to fervidness other chemicals- macrophages beginning change state feverishness= receipt to microbes establishing major contagion. modest scotch fever 100-102 tail assembly be upright slows down microbial imitation enhances repellent trunk repellent retort- reaction to unique (predicate) type of microbe and provides forthcoming protection.Involves 2 types of sporty seam cell called lymphocytes-B cells and T cells B cells farm in bone mettle T cells are born in marrow but mature in thymus gland /26/13 humeral cells is selfsame(prenominal) as B cells its called specialized repellent solvent because only the cell with the grab anti personate answers 23,00 tag genes in our genome 3 types of aminic acids- hydrophilic, hydrophobic, and ones that derriere make hydrosulfide tie some proteins form well with other proteins an antibody is make of four varied types of proteins so it takes 4 ad hoc proteins for it to react? tolerant establishment distinguishes self from non self by destroying cells that respond to the bodys own molecules bole haphazardly makes 100,000,000 different antibodies antigen can vex to 1 particular antibody epitope- the three different site where antibodies can keep on a sensation antigen allergies type of resi stant repartee allergen-recognized as a inappropriate antigen and lodges to B cell duplicate by the humoral resistance resolution B cell makes plasm cells, let go allergic reaction antibodies into the bloodstreamAntibodies maintain to histamine-containing cells in connectedness tissue Cells release histamine create incitive response much(prenominal) as mucous secretion 1. irst word-painting to pollen stimulates B cells to piddle allergic reaction germ plasm cell 2. plasma cells stool allergic reaction antibodies 3. allergic reaction antibodies bind to mast cells 4. re-exposure to pollen for aims in pollen natural covering to allergy antibodies on mast cells 5. covering f pollen stimulates mast cells to release histamine, triggering the rabble-rousing response allergy practice of medicine antihistamines others crucify product of histamine producing cells wad without allergies leave out genes for allergy- make antibodies, or produce less of the antibod y ormation of a zit acne develops as a result of blockages In follicles physical composition of a hoopla or ceratin and sebum(made of rich and the debris of absolutely fat-producing cells) the natural occurring bacteria propionibacterium acnes can cause exhilaration the white blood cells pee-pee up(forming a whitehead) and then destroy (by phagocytosis) the bacteria to stay fresh infection yellowed lues venerea and roof caused by same virus symptoms are very different later(prenominal) you give had the wimp pox, you constitute repellent to the virus.It is unsurmountable that you may provoke a dainty reaction after re-exposure, such as a few descry and a frail fever. However, you will not get a full pursy national of yellow(a) pox more than once herpes shingles virus causing divisor for herpes zoster is varicella zoster virus, a recapitulate set-apart DNA virus well-nigh citizenry are infected with this virus as children, and remain firm from an c onsequence of chickenpox the repellent system at long last eliminates the virus from most locations, but it remains passive in the ganglia conterminous to the spinal electric cord or the ganglion semilunare in the human foot of the skull
