Non self substance, plasma membrane and stimulate the production of antibodies
1 of 27
polypeptide, production of lympctye, binds to antigens
2 of 27
clonal selection
Vast number of identical plasma cell which respond to antigen
3 of 27
to many different B cells activated
4 of 27
Antigen production
1. engluf antigen my macrophage 2.macrophage presents antigen on its protien, initates helper t cell 3.activation of t cell, 4.activate b cell 5. clone antibody- b cells divide, memory cells
5 of 27
active immunity
persistance of memory cells upon reinfection antibodies are produced quicer and destroyed before symptoms show
6 of 27
Passive immunity
anitbody from another organism where immunity is stimulated e.g. placenta
7 of 27
COntains antigen which trigger immunity but dont cause the disease, 2 types - inactivated and alternuated
8 of 27
allgeric response
antigen enters, releases histomenes, binds to receptors causing them to become leaky, causing symptons
9 of 27
block action of histomines at receptors
10 of 27
Monocolonal antibodies
Large quantites of single antibody-- 1. lab animal injected with antibody 2.produces B lymphocytes 3.removed and fused with tumour cells forms hybridoma 4. divide and produces on type of antibody
11 of 27
Pregnancy test
Urine with HCG moves up *****, attaches to mobile HCG with coloured granuales, immobile trap the mobile and a blue colour appears, they then combine to cause another blue *****
12 of 27
removal of waste products of metabolic pathways and processes e.g. urea
13 of 27
organism which control solute concentration of blood
14 of 27
allow internal concentration to be the same as other solutes in environment
15 of 27
ADH released by pituatry, walls of collecting duct become impermable large dilute urine
16 of 27
ADH released, walls become permable, small amount of concentrated urine
17 of 27
ultra filtration in glomerous
filtration of blood under pressure, small molecules are filtered out of the blood into bowmans capsule, promoted due to high blood pressure
18 of 27
waste prodcuts
Fish- aquatic habitiat, amonia waste, toxic but dilutes birds- terrestral, urine acid waste, non toxic mammals- terrestial aquatic, urea, low toxic
19 of 27
detecting kidney issues
urine test to test for blood, glucose, protiens drugs ----- treatment - tranplant or haemodralysis
20 of 27
Blood drawn from the arm passed through a machine for 3/4 hrs, pores in membrane allow small particles to pass through but not protiens or blood
21 of 27
Production of male gametes - mitosos, cell growth, meiosis to prodcue haploid cells annd then differenciated into gametes
22 of 27
arrival-binding-acrosome reaction-corticial reaction-mitosis
23 of 27
Human chronic gonactrophin (HCG)
secreted by blasosyst then after 16 weeks preg relaeased from placenta role=maintains corpus luteum and maintains uterus lining
24 of 27
disc shaped, many projections called billi, blood of fetus flows close to mothers blood, so allows exchange of materail
25 of 27
maternal to fetus exchange
oxygen, glucose, lipids, water, amino acids, hormones
26 of 27
fetus to mother
c02, urea, hormones and water
