Yuav ua li cas yog lub cev? Thiab yog vim li cas yog nws tsim nyog?

Lub cev ntawm ib tug neeg - ib tug sau ntawm hlwb, ntaub so ntswg thiab kabmob uas yog lub luag hauj lwm rau kev pab tiv thaiv tawm tsam txawv teb chaws kab mob thiab tshuaj, raws li zoo raws li lawv tus kheej hlwb, uas nws caj kev pab cuam yog lawm (piv txwv li, mob hlwb). Nyob rau hauv lub rooj plaub uas nyob rau hauv no system muaj kev puas tsuaj los yog malfunctions, qhov no ua rau tus tuag ntawm tag nrho cov kab mob.

Cheebtsam ntawm tus tib neeg lub cev

Rau hnub tim, tus tib neeg tsis muaj zog yog sawv cev raws li ib tug ua ke ntawm cov nram qab no nruab nrog cev, cov nqaij thiab hlwb:

1. Lub hauv paus lymphoid kabmob (lymphoid formations ntawm lub appendix, lymphoid formations cov nyuv, me nyuam hauv plab lub siab, hloov hlwb pob txha thiab thymus).
2. Ntawm peripheral lymphoid kabmob (po thiab cov qog ntshav).
3. Immune hlwb (monocytes, lymphocytes, polynuclear ntshav dawb, Langerhans hlwb, thiab lwm yam).

Nyob rau hauv cov ntaub ntawv no, rau lub qub hauj lwm ntawm lub cev yog ib qho tseem ceeb tag nrho lub hlwb, ntaub so ntswg thiab kabmob. Hloov khoom nruab nrog nruab (digestive, urogenital, thiab lwm tus) yog txaus xav nyob ntawm seb nyob rau theem ntawm kev tiv thaiv. Nyob rau hauv hais tias rooj plaub no nws yog txo nyob rau hauv qhov kev txiav txim zuj zus uas yuav muaj kev loj hlob ntawm tej yam kab mob, raws li tau zoo raws li qhov tshwm sim ntawm tag nrho ob qho benign thiab phem hlav. Thiaj li, lub cev tsis muaj zog plays ib qho tseem ceeb luag hauj lwm nyob rau hauv nws lub neej.

Yuav ua li cas puas muaj tus tsis muaj zog?

Lub cev lus teb rau cov kev taw qhia txog lub microorganism yog nqa tawm nyob rau cov nuj nqis ntawm lub hlwb xws li leukocytes. Lawv tuaj nyob rau hauv ob peb ntau yam: qe (nkaug, segmented, basophils, thiab eosinophils), monocytes thiab lymphocytes (B-lymphocytes, T-lymphocytes thiab NK-hlwb). Nws yog tus thawj mus cuag Neutrophil infiltration kab mob rau ntawm qhov chaw thiab pib ua kom puas txawv teb chaws microorganisms. Nyob rau tib lub sij hawm lawv ua ib txoj hauj lwm zoo nrog cov kab mob. Yog hais tias lub cev mus rau cov kab mob, nws yog ntau npaum li cas zoo tiv thaiv cov hlwb.

Sib nrug los ntawm qhov tseeb hais tias tus tib neeg tsis muaj zog muaj peev xwm mus suppress feem ntau ntawm cov paub kab mob, nws tseem muaj peev xwm "nco ntsoov" ntau ntawm lawv nyob rau hauv cov ntaub ntawv ntawm re-kab mob los ntawm lawv tiv nrog lub xeeb txob sai npaum li cas (thiab muaj tsawg losses rau tus kab mob).

Nws yuav tsum tau muab sau tseg hais tias lub cev, ua heev pab tau, muaj peev xwm mus pheev tsis zoo los rau tib neeg lub neej. Qhov no yog feem ntau kom meej meej manifested tom qab hloov hloov. Qhov tseeb yog hais tias vim lub fact tias lub cev perceives cov ntaub so ntswg pub hloov raws li txawv teb chaws, feem ntau tshwm sim ib cov tshuaj tiv thaiv ntawm rejection. Raws li ib tug tshwm sim, cov neeg yuav tsum nqa tawm txoj kev tshawb fawb thiab xyoo nyob tos rau ib tug haum pub. Nyob rau hauv tas li ntawd, lub cev tej zaum cheeb ib tug poj niam daig nyob rau hauv nws cov txiv neej cov phev, vim hais tias, dua, pib xav txog lawv alien thiab txaus ntshai rau lub cev. Raws li ib tug tshwm sim, muaj ib tug thiaj li hu ua immunological incompatibility ntawm cov neeg koom tes. Yuav kom qhov no khub yuav ua rau lawv cov me nyuam, ib tug poj niam muaj noj immunosuppressive tshuaj. Nyob rau hauv cov ntaub ntawv uas, yog hais tias tus niam yog v tsis zoo ntshav thiab lub fetus - yog zoo, thaum lub sij hawm xeeb tub thawj zaug, nws yuav txhaj tshuaj tiv thaiv. Raws li ib tug tshwm sim, tom ntej no tus me nyuam, yog hais tias nws yuav kuj yuav lub neeg uas hnov txog zoo v tau, tej zaum yuav raug mus rau qhov no nres los ntawm lub cev ntawm nws niam, uas leads mus rau kev loj hlob ntawm ib tug txaus heavy-taus tej yam kev mob, xws li cov me nyuam hauv plab thiab tus poj niam nws tus kheej.
