Hom cell feem ntau hauv cov ntaub so ntswg lymphoid yog lymphocyte. Zoo li macrophages, lymphocytes yog tsim los ntawm qia hlwb nyob rau hauv cov pob txha pob txhathiab tom qab ntawd ntws hauv cov ntshav mus rau cov ntaub so ntswg lymphoid. T lymphocytes mature nyob rau hauv lub thymus ua ntej mus rau lwm yam lymphoid organ, xws li tus po.
Cov ntaub so ntswg lymphoid yog dab tsi?
Nws muaj cov ntaub so ntswg uas tsim los ntawm cov fibers reticular, nrog ntau hom leukocytes (cov qe ntshav dawb), feem ntau lymphocytes enmeshed nyob rau hauv nws, los ntawm cov lymph mus. Cov cheeb tsam ntawm cov ntaub so ntswg lymphoid uas ntim nrog cov lymphocytes yog hu ua lymphoid follicles.
Thaum twg cov ntaub so ntswg lymphatic tsim?
Limphatic cov ntaub so ntswg pib tsim los ntawm kawg ntawm lub lim tiam thib tsib ntawm kev loj hlob ntawm embryonic. Lymphatic hlab ntsha tsim los ntawm cov qog nqaij hlav uas tshwm sim los ntawm kev tsim cov hlab ntsha, uas tau muab los ntawm mesoderm.
Vim li cas peb thiaj tau cov ntaub so ntswg lymphoid?
Lymphoid cov ntaub so ntswg yog cov txheej txheem uas txhawb kev tiv thaiv kab mob. Cov pob txha pob txha thiab thymus yog thawj cov ntaub so ntswg lymphoid thiab qhov chaw ntawm lymphocyte kev loj hlob. Cov qog nqaij hlav, spleen, tonsils thiab Peyer's thaj ua rau thaj yog piv txwv ntawm cov ntaub so ntswg lymphoid.
Lim ntshav yog dab tsi thiab nws ua li cas?
Lymph yog cov kua dej ntshiab-rau-dawb ua los ntawm: cov qe ntshav dawb, tshwj xeeb tshaj yog cov lymphocytes, cov hlwb uas tawm tsam cov kab mob hauv cov ntshav. Cov kua dej los ntawm cov hnyuv hu ua chyle, uas muaj cov protein thiab rog.

Leej twg tsim cov ntaub so ntswg perforated?
HISTORY: Ua tsaug, Seth Wheeler, tus tsim khoom ntawm cov ntaub so ntswg perforated. Vim peb paub tias koj tau xav tsis thoob, nws yog tag nrho Seth lub tswv yim. Lub tswv yim ntawm dov thiab perforated squares ntawm daim ntawv tso quav tso zis yog patented nyob rau hauv 1883 los ntawm Seth Wheeler .
Dab tsi yog mucosa cuam tshuam cov lymphoid cov ntaub so ntswg?
Mucosa-associated lymphoid cov ntaub so ntswg (MALT) yog scattered raws mucosal linings hauv tib neeg lub cev [ 1 , 2 , 3 thiab suav nrog feem ntau ntawm cov ntaub so ntswg lymphoid tib neeg. Cov chaw no tiv thaiv lub cev los ntawm ntau qhov ntau thiab ntau yam antigens.
Vim li cas cov ntaub so ntswg meristematic muaj cov nucleus tseem ceeb?
Meristematic hlwb muaj lub hauv paus tseem ceeb, ntom cytoplasm thiab tsis muaj vacuoles thiab vim tias: cov cells tsis khaws cov khoom noj lossis cov khoom pov tseg. Yog li lawv tsis muaj vacuole. Raws li vacuoles muaj cell sap thiab muab rigidity thiab turgidity rau lub cell .
Puas yog cov ntaub so ntswg adipose suav tias yog cov ntaub so ntswg txuas?
Adipose cov ntaub so ntswg, lossis cov ntaub so rog, cov ntaub so ntswgsuav nrog cov roj ntsha tseem ceeb (adipose hlwb, lossis adipocytes), tshwj xeeb los ua ke thiab muaj cov roj loj loj, hauv cov qauv network ntawm fibers . Puas yog cov ntaub so ntswg adipose txuas?
Vim li cas cov noob orchid germinated hauv cov ntaub so ntswg?
Germinating cov noob hauv vitro tso cai rau tus neeg cog qoob loo kom hla cov kev txwv uas cuam tshuam cov noob qoob loo thiab kev loj hlob ntawm cov noob, feem ntau yuav tsum muaj cov kab mob tshwj xeeb kom germinate thiab loj hlob . Yuav ua li cas cov ntaub so ntswg propagate orchids?
