Muaj peb lub ntsiab hom lymphocytes : B hlwb, T hlwb, thiab ntuj killer hlwb. Ob tug ntawm no hom lymphocytes yog qhov tseem ceeb rau cov lus teb tiv thaiv kab mob tshwj xeeb. Lawv yog B. cov lymphocytes (B cells) thiab T. cov lymphocytes (T hlwb).
Nyob rau hauv no, dab tsi yog 3 chav kawm ntawm lymphocytes thiab txhua chav kawm yog qhov twg?
Muaj peb hom ntawm cov lymphocytes , hu ua T cells, B cells, thiab cov neeg tua neeg ntuj. T cells tau txais lawv lub npe vim tias lawv tau tsim los ntawm cov qog thymus. Cov hlwb no txawv ntawm lwm yam cov lymphocytes los ntawm tshwj xeeb T-cell receptor molecule uas yog nyob rau ntawm qhov chaw ntawm lub cell.
Kuj Paub, 2 hom lymphocytes yog dab tsi? Cov lymphocyte yog hom qe ntshav dawb uas yog ib feem ntawm lub cev tiv thaiv kab mob. Muaj ob hom tseem ceeb ntawm lymphocytes: B cells thiab T hlwb . B cells tsim cov tshuaj tiv thaiv uas siv los tua cov kab mob, cov kab mob, thiab cov tshuaj lom.
Ib tus kuj tseem yuav nug, 5 hom lymphocytes yog dab tsi?
Cov ntsiab lus hauv cov teeb no (8)
- t-lymphocytes. ua 80 feem pua ntawm cov qog ntshav lymphocytes.
- pab t cells. hom tshwj xeeb ntawm t cells uas txhawb kev ua haujlwm ntawm ob lub t thiab b cell.
- b-lymphocytes. ua li 10-15 feem pua ntawm cov qog ntshav lymphocytes.
- plasma hlwb.
- ntuj tua cov cell.
- macrophages.
- reticular hlwb.
- dendritic hlwb.
Puas yog cov cell B ncig hauv cov ntshav?
Tom qab B hlwb mature nyob rau hauv cov pob txha pob txha, lawv migrate los ntawm lub ntshav rau SLOs, uas tau txais qhov muab tas li ntawm antigen los ntawm ncig cov qog ntshav.

Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Vim li cas peb thiaj sau cov ntshav los ntawm cov hlab ntsha thiab tsis yog los ntawm cov hlab ntsha?
Cov leeg yuav tsum tau li qub kom cov ntshav ntws mus rau lub plawv. Theses li qub yog qhov tshwj xeeb hauv ob txhais ceg thiab caj npab. Lawv tawm tsam lub ntiajteb txawj nqus los tiv thaiv cov ntshav rov qab los. Cov hlab ntsha tsis xav tau li qub vim tias lub siab los ntawm lub plawv ua kom cov ntshav ntws los ntawm lawv mus rau ib qho
Cov hlab ntsha hauv lub ntsws txawv li cas ntawm cov hlab ntsha hauv nruab nrog cev?
Cov hlab ntsha. Cov hlab ntsha hauv lub ntsws nqa cov ntshav oxygen tsawg los ntawm txoj hlab ntshav ntawm lub plawv mus rau lub ntsws. Cov hlab ntsha hauv lub cev thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Cov leeg
Dab tsi yog peb hom hlab ntsha hauv cov hlab ntsha?
Muaj peb yam tseem ceeb ntawm cov hlab ntsha: cov hlab ntsha. Lawv nqa cov ntshav uas muaj oxygen tawm ntawm lub plawv mus rau tag nrho lub cev cov ntaub so ntswg. Capillaries. Cov no yog cov hlab ntshav me me, uas txuas cov hlab ntsha thiab cov leeg. Cov leeg
