Abaningi baye bazwa ngomqondo onjenge-lymph, kodwa akuwona wonke umuntu owazi ukuthi uyini, ukuthi wenzani nokuthi kungani kuyadingeka. Kuthathwa njengezicubu ezimanzi, ezitholakala ezitokisini ezihambelanayo nama-node. Ngosuku lungenza ama-alitha amane. I-lymph iyisilawuli esicacile esinabantu abangaphezu kwe-1,026. Igcina ukulinganisela kwamanzi emzimbeni, futhi isusa amagciwane avela kumathishu.
Indlela yokufundisa
Esigabeni sokuqala sokubunjwa kwe-lymph, izicubu zamanzi ziyimfihlo kusuka eplasma yegazi. Lokhu kwenzeka njengomphumela wokuhlunga okwakamuva kule capillaries. Amanzi nama-electrolyte ahlanganiswa nezinye izakhiwo. Yileyo ndlela ivela ngayo i-tissue fluid, ingxenye yayo ebuyela emuva egazini, kanti ezinye izinhlobo ze-lymph kuma-capillari afanayo. Lokhu kubonisa ukuthi kukhona kuphela kwimvelo yangaphakathi yomzimba.
Ukwakhiwa kwe-lymph
Izicubu zamanzi zidlula ezitsheni zesimiso se-lymphatic. Lokhu kumnika ithuba lokungena cishe zonke izingxenye zomzimba. Okubaluleke kakhulu, kubonakala ezithombeni lapho zikwazi khona ukuphakama okukhulu kwemithambo yegazi. Okugcwele kunazo zonke yizinhliziyo, uhlangothi lwesibindi, isibindi namasipha omzimba.
Kubalulekile ukuthi uqaphele ukuthi ngo-lymph, ngokungafani negazi, ukwakheka kushintsha njalo. Iqiniso liwukuthi lixhomeke ngqo ezinduneni nasezikhungweni ezivela lapho zigeleza khona. Ngokuvamile, izingxenye eziyinhloko zihlale zikhona:
- amanzi;
- i-leukocyte;
- i-lymphocytes;
- izakhi ezakhiwe ngenxa yokwehla kwama-organic compounds.
Ngaphezu kwalokho, ukubunjwa nakho kungabonwa ama-enzyme, amavithamini nezinto ezikhulisa i-blood coagulability. Uma kunomonakalo kuma-capillary, inani le-lymphocyte liqala ngokuzenzakalelayo. Ayikho iplatelet kulokhu okuketshezi, kodwa kusenayo impahla ye-coagulation, ngoba iqukethe i-fibrinogen. Ngaphezu kwalokho, ngaphansi kwezimo ezihlukene ekubunjweni kungatholakala i-lysozyme, i-cordin futhi igcwalise.
Umthetho we-lymphogenesis
Ukulawulwa kwalolu hlelo kuhloswe ikakhulukazi ekwandiseni noma ekunciphiseni ukuhlanzwa kwamanzi nezinye izingxenye ezifaka i-plasma. Le nqubo iyenzeka ngenxa yomsebenzi wesimiso sezinzwa ezizimele, okusebenzisa izinto ezihlaziyekayo-i-humoral-vasoactive ezikwazi ukuguqula ukucindezeleka kwegazi kanye nokuqedwa kwezindonga zamanzi.
Ngaphezu kwalokho, yonke inqubo ishintshwe yi-oncotic pressure. Naphezu kokubonakala okuphansi kwamadonga ama-capillaries, bangadlula ku-200 g amaprotheni ngosuku ngosuku olusetshenziselwa uketshezi olusuka kuwo. Lokhu kwandisa ingcindezi, ngenxa yalokho amanzi asetshenziselwa ngokugcwele, okusheshisa ukuphuma kwalesi sici - isigaba se-ejection sakhiwa.
Wonke amaprotheni ayengatholwa emuva egazini abuyele emuva, kuphela nge-lymphatic system. Ngolunye usuku, amaprotheyini angama-50 kuya ku-100% angabuyekezwa kabusha. Lo mqondo ubizwa ngokuthi "uMthetho Oyisisekelo We-Lymphology".
Ngaphezu kwalokho, ezinye izindlela zenza ukuba kuvele ukuphuma: amandla okusebenzisana ezindongeni zemikhumbi, ukutholakala kwezinto zokufakelwa kwe-valve, ukuqhubekela phambili kwegazi eduze kwezikebhe ezingomakhelwane, nokucindezela okubi esifubeni.
Imisebenzi emikhulu
I-lymph ayithinti nje kuphela izitho lapho zakha khona. Ihlanganyela ezinkambisweni eziningi, okubaluleke kakhulu kuzo
- ukugcinwa kokwakhiwa okuqhubekayo koketshezi kwamaseli;
- amaprotheni abuyela egazini;
- ukusatshalaliswa okulungile komswakama kuwo wonke umzimba;
- ukuqinisekisa ukuxhumana phakathi kwezitho nezicubu;
- ukugcinwa kwegciwane lesandulela ngculazi ngokudluliselwa kwama-antibodies kanye nama-antigens;
- ukulawulwa kwe-metabolism ngokuthutha ama-enzyme namaprotheni.
