Ntau tus tau hnov txog lub tswv yim xws li cov qog, tab sis tsis yog txhua tus paub tias nws yog dab tsi, nws tsim dab tsi thiab vim li cas nws thiaj xav tau. Nws yog xam cov kua nqaij, uas nyob hauv cov hlab ntsha thiab cov ntshav. Nyob rau hauv ib hnub nws muaj peev xwm ua li plaub liters. Cov qog no yog cov kua ntshiab ntshiab nrog rau qhov ceev tsis tshaj 1.026. Nws tswj cov dej hauv lub cev, thiab tshem tawm cov kab mob ntawm cov nqaij.
Cov mechanism ntawm kev kawm
Thaum thawj theem ntawm cov qog nqaij hlav, cov kua nqaij kua qaub los ntawm cov ntshav ntshav. Qhov no tshwm sim los ntawm kev pom ntawm cov tom kawg hauv lub capillaries. Dej thiab electrolytes yog sib xyaw nrog lwm cov qauv. Qhov no yog li cas cov kua ntswg tshwm tuaj, ib feem ntawm cov dej uas rov mus rau hauv cov ntshav, thiab so - cov qog cov qog nyob rau hauv cov hlab ntsha tiv thaiv. Qhov no qhia tau hais tias nws tshwm sim hauv ib puag ncig ntawm lub cev.
Muaj pes tsawg leeg ntawm cov qog
Cov kua nqaij kis tau los ntawm cov hlab ntsha ntawm lub cev lymphatic. Qhov no ua rau nws muaj lub cib fim mus rau hauv txhua qhov ntawm lub cev. Feem ntau ntawm tag nrho cov, nws yog pom nyob rau hauv kabmob uas lawv muaj ib tug siab permeability ntawm cov hlab ntsha. Cov kab uas ntim tshaj plaws yog lub plawv, spleen, daim siab thiab daim tawv nqaij pob txha.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias nyob rau hauv cov qog ntshav, hauv qhov sib piv rau cov ntshav, ntawm cov kab tsim tshuaj txhua zaus hloov. Qhov tseeb yog tias nws ncaj qha nyob ntawm cov ntaub so ntswg thiab kabmob los ntawm qhov chaw nws ntws. Nyob rau hauv dav dav, lub ntsiab yam yog ib txwm:
- dej;
- leukocytes;
- lymphocytes;
- ntsiab uas tsim tawm raws li ib tug ntawm cov decomposition ntawm cov organic sib txuas.
Nyob rau hauv tas li ntawd, lub composition kuj yuav tau pom cov enzymes, cov vitamins thiab tshuaj uas nce ntshav coagulability. Yog tias muaj kev puas tsuaj rau cov hlab ntsha, cov lymphocytes tuaj yeem pib nce. Tsis muaj platelet hauv no kua, tab sis nws tseem muaj cov cuab yeej ntawm coagulation, vim nws muaj fibrinogen. Tsis tas li ntawd, nyob rau hauv ntau yam nyob rau hauv muaj pes tsawg tus muaj peev xwm nrhiav tau lysozyme, correctdin thiab qhuas.
Kev cai ntawm lymphogenesis
Cov kev cai tswjfwm ntawm txoj haujlwm no yog tsim los ntawm kev tsim lossis txo qhov kev lim dej thiab lwm yam khoom uas nkag rau hauv cov ntshav. Cov txheej txheem no tshwm sim vim kev ua haujlwm ntawm lub cev tsis muaj zog, uas yog los ntawm cov khoom siv humoral-vasoactive muaj peev xwm hloov ntshav siab thiab cov kab mob ntawm cov hlab ntsha.
Tsis tas li ntawd, tag nrho cov txheej txheem cuam tshuam los ntawm oncotic siab. Txawm tias muaj tsawg permeability ntawm cov phab ntsa hauv capillaries, lawv tuaj yeem hla mus txog 200 g ntawm cov protein ib hnub hauv cov kua, los ntawm cov kua uas tsim tawm. Qhov no ua rau kom muaj zog, vim tias cov dej muaj qhov muag zoo heev, uas ua rau cov kev tawm ntawm cov khoom no tawm mus - muaj cov ejection theem.
Tag nrho cov proteins uas yav tas los tau los ntawm cov ntshav rov qab los, tsuas yog los ntawm cov kab xev fais fab. Rau ib hnub, kev siv dua 50 mus rau 100% muaj protein ntau. Cov tswvyim no yog hu ua "Basic Law of Lymphology".
Tsis tas li ntawd, lwm cov tswv yim ua rau kev tawm mus: qhov nruab nrab ntawm cov leeg cog lus ntawm cov phab ntsa ntawm cov hlab ntsha, muaj lub plhaub tws, qhov kev vam meej ntawm cov ntshav nyob ze cov hlab ntsha, thiab kev siab tsis zoo hauv lub hauv siab.
Lub luag haujlwm tseem ceeb
Lymph cuam tshuam tsis tau tsuas yog lub plab hnyuv siab raum uas nws tshwm sim. Nws koom nrog ntau cov txheej txheem, qhov tseem ceeb tshaj plaws ntawm cov uas
- kev tu vaj tse ntawm qhov muaj pes tsawg leeg nyob hauv hlwb;
- protein rov qab los rau cov ntshav;
- kev faib cov kua dej thoob plaws lub cev;
- txav kev sib txuas lus ntawm nruab nrog cev thiab cov ntaub so ntswg;
- kev tiv thaiv ntawm kev tiv thaiv los ntawm kev hloov ntawm cov tshuaj tiv thaiv thiab antigens;
- cov cai ntawm cov metabolism hauv kev thauj cov enzymes thiab proteins.
