Ukubuka konke

Umzimba uqukethe kakhulu uketshezi. Wonke amaseli ayo aqukethe futhi azungezwe uketshezi. Ngaphezu kwalokho, amalitha egazi amane kuya kwayisihlanu ajikeleza ngohlelo lwezinhliziyo nganoma yisiphi isikhathi. Elinye lelo gazi liyaphunyuka ohlelweni njengoba lidlula emithanjeni yegazi emincane ebizwa ngokuthi ama-capillary ezicutshini zomzimba. Ngenhlanhla, kukhona "uhlelo lwesibili lokujikeleza kwegazi" oluphindaphinda luphume uketshezi bese lubuyela emithanjeni.

Lolo hlelo uhlelo lwe-lymphatic. Ihamba ngokufana nemithambo bese ithululela kuyo. Amafomu e-lymph ezingeni elincane. Imithambo emincane, noma ama-arterioles, aholela kuma-capillary, nawo aholele emithanjeni emincane, noma emithanjeni yegazi. Ama-capillaries amaLymph asondele eduze kwama-capillaries egazi, kepha awaxhunyiwe empeleni. Ama-arterioles aletha igazi kuma-capillaries asuka enhliziyweni, futhi ama-venule asusa igazi kuma-capillaries. Njengoba igazi ligeleza ngama-capillaries lingaphansi kwengcindezi. Lokhu kubizwa ngokuthi ingcindezi ye-hydrostatic. Le ngcindezi iphoqa olunye uketshezi olusegazini luphume kuyi-capillary luye ezicutshini ezizungezile. Umoya-mpilo ovela kumaseli abomvu egazi, nezakhamzimba ezikulolu ketshezi bese zingena ezicutshini.

Isikhutha nesikhutha semfucumfucu esikhunjeni zisakazeka zibuyele egazini. Ama-capillaries abuyisela kabusha uketshezi oluningi. Ama-lymph capillaries amunca lokho okusamanzi okusalayo.

I-Edema, noma ukuvuvukala, kwenzeka lapho uketshezi ngaphakathi noma phakathi kwamaseli kuvuza ezicutshini zomzimba. Kubangelwa izehlakalo ezandisa ukuphuma koketshezi oluphuma egazini noma zivimbele ukubuya kwalo. I-edema eqhubekayo ingaba uphawu lwezinkinga ezinkulu zempilo futhi kufanele ihlolwe nguchwepheshe wezokunakekelwa kwempilo.

Uhlelo lwe-lymphatic lungadlala indima enkulu ekukhathazekeni komdlavuza webele.

Ama-lymph node ahlunga i-lymph njengoba idlula ohlelweni. Zitholakala ezindaweni ezithile kuwo wonke umzimba njengasemakhwapheni futhi ziphezulu emphinjeni.

Ukujikeleza kweLymphatic ezicutshini zamabele kusiza ekulawuleni ibhalansi lendawo yamanzi kanye nokuhlunga izinto eziyingozi. Kodwa uhlelo lwe-lymphatic lwebele lungasabalalisa nezifo ezifana nomdlavuza emzimbeni.

Imikhumbi yeLymphatic inikeza umgwaqo omkhulu lapho amaseli anomdlavuza ahlasela khona kwezinye izingxenye zomzimba.

Le nqubo ibizwa ngokuthi i-metastasis. Kungaholela ekwakhekeni kwesisindo somdlavuza wesibili kwenye ingxenye yomzimba.

Le mammogram ikhombisa isimila nenethiwekhi yomkhumbi i-lymph esihlasele kuyo.

Akekho umuntu wesifazane osemncane kakhulu ukuthi angazi ukuthi ukuzihlola njalo amabele kungasiza ekubambeni izicubu ngaphambi kokukhula kwazo, ngethemba ngaphambi kokuba zisabalale noma zisasaze.
