Wake wazibuza ukuthi imfucuza nezinto ezingadingeki ezingaphakathi emizimbeni yethu zisuswa kanjani? Njengoba nje amanzi angcolile edlula emapayipini endlini, imizimba yethu nayo inesimiso esifanayo. Lokhu sikubiza ngokuthi uhlelo lwe-lymphatic. Ngakho-ke namuhla sizokhuluma ngomsele oyinhloko, omkhulu nobaluleke kakhulu kulesi simiso. Lowo umsele wesifuba. Kungenzeka ukuthi awukaze uzwe ngaleli gama ngaphambili. Kodwa lo ngumuntu owenza inkonzo enkulu emizimbeni yethu buthule.
Kalula nje, iyini i-Thoracic Duct?
Kalula nje, i-Thoracic Duct iyisitsha esikhulu kunazo zonke se-lymphatic emzimbeni wakho . Yisakhiwo eside esifana ne-tube esiqala esiswini sakho, sigijimele esifubeni sakho, bese siphela eduze kwentamo yakho.
Cabanga ngakho njengomgwaqo omkhulu onemigwaqo eseceleni ehlangana ndawonye, uketshezi olubizwa ngokuthi "i-lymph" oluqoqana emigudwini emincane ye-lymph emizimbeni yethu luhlangana nalo msele omkhulu. Bese lo msele wesifuba uxhuma emthanjeni wegazi omkhulu "umthambo" eduze kwentamo, bese ukhulula lolo ketshezi lwe-lymph lubuyele ohlelweni lwethu lokujikeleza kwegazi. Ukusuka lapho, luhamba emzimbeni wonke futhi.
Kunezindlela ezimbili eziyinhloko zokubuyiselwa koketshezi lwe-lymph egazini emzimbeni wethu.
1. Umsele Wesifuba
2. Umsele We-Lymphatic Wangakwesokudla
Umsele we-lymphatic ongakwesokudla uqoqa i-lymph engalweni yakho yokunene, ohlangothini lokunene lwekhanda lakho nentamo, kanye nohlangothi lokunene lwesifuba sakho bese uyibuyisela egazini lakho. Kodwa-ke, umsele wesifuba uqoqa i-lymph cishe kuzo zonke ezinye izingxenye zomzimba wakho .
| Igama lesiteshi | Izindawo lapho uketshezi lwe-lymph luqoqa khona |
|---|---|
| Umsele Wesifuba | Uhlangothi lwesobunxele lwekhanda, intamo, kanye nesifuba Indawo yesisu (isisu) Imilenze yomibili |
| Umsele We-Lymphatic Wesokudla | Uhlangothi lwesokudla lwekhanda, intamo, kanye nesifuba Isandla sokunene |
Uyini umsebenzi waleli payipi?
Umsebenzi oyinhloko womgudu wesifuba ukuqoqa i-lymph kusuka eziteshini ezincane ze-lymph ezingxenyeni ezahlukene zomzimba bese uyiletha ohlelweni lwethu lokujikeleza kwegazi. Lokhu kusiza ukugcina amazinga oketshezi anempilo emzimbeni wethu futhi kuhlunge imikhiqizo engcolile.
Ake sibone ukuthi le nqubo isebenza kanjani isinyathelo ngesinyathelo:
1. Ukuqoqwa: Okokuqala, uketshezi lwe-lymph luqoqana kusuka kuma-capillary amancane kakhulu e-lymphatic asakazeke kuwo wonke umzimba bese lungena emithanjeni ye-lymphatic emikhudlwana kancane.
2. Ukuza emgwaqweni omkhulu: Njengoba nje imigwaqo emincane eseceleni ihlangana ukuze yakhe umgwaqo omkhulu omkhulu, yonke le mithambo emikhulu ye-lymphatic iyahlangana futhi ixhumeke emgudwini wesifuba. Umgwaqo omkhulu lapha umgudwini wesifuba.
3. Ukwenyuka: Le lymph ibe isihamba iye phezulu ngepayipi lesifuba. Lolu hambo luyaqhubeka luze lufike entanyeni.
4. Ukuxubana negazi: Ngemva kokufinyelela endaweni ekhethekile yokuhlangana (i-lymphovenous junction - LVJ) ohlangothini lwesobunxele lwentamo, umgudu wesifuba uhlangana nomthambo omkhulu lapho. Njengemoto engena emgwaqweni omkhulu, uketshezi lwe-lymph lungena emthanjeni ngalo mgudu. Ukusuka lapho, lujikeleza kuwo wonke umzimba njengengxenye ye-plasma yegazi lethu.
Nsuku zonke, sifaka cishe amalitha amathathu oketshezi ohlelweni lwethu lokujikeleza kwegazi ngomsele wesifuba kuphela. Akumangalisi ngempela lokhu?
Kukhona uhlobo olukhethekile loketshezi lwe-lymph. Lubizwa ngokuthi 'chyle' . Lolu uketshezi oluvela ohlelweni lwethu lokugaya ukudla futhi lunamafutha amaningi. Ngokungafani nolunye uketshezi lwe-lymph, lolu ketshezi 'chyle' lumhlophe njengobisi.
Ikuphi i-thoracic duct?
Itholakala phakathi kwesifuba sakho . Itholakala eduze kwe-aorta yethu, umphimbo, nomgogodla.
Iqala emhlane ongezansi, emgogodleni we-lumbar. Kwabaningi, iqala phakathi kwamathambo e-T12 kanye ne-L2. Iqala lapho iziteshi eziningana ze-lymph ezivela emilenzeni nasemathunjini ethu zihlangana ndawonye. Ngezinye izikhathi, kwakheka isakhiwo esifana nesikhwama lapho lezi ziteshi zihlangana khona. Ibizwa ngokuthi 'i-cisterna chyli' .
Ukusuka lapho, lo msele uhamba uqonde phezulu esifubeni (esifubeni). Endleleni, uhlanganiswa neminye imithambo ye-lymphatic. Uma ufika entanyeni, ugoba ube yi-arch ngaphezu kwe-collarbone, bese wehla futhi ukuze ujoyine umthambo osesifubeni esingaphezulu.
Lokhu kuhlobene kuphi ngempela?
Indawo yalokhu kuxhumana ingahluka kancane kumuntu nomuntu. Ngokuvamile, yilapho umthambo we-subclavian wesobunxele kanye nomthambo we-jugular wangaphakathi kwesobunxele uhlangana khona. Kwabanye abantu, ungase uxhumeke komunye wale mithambo ngokwehlukana.
Akudingeki ukuthi uwazi kahle la magama, kodwa kubalulekile ukuthi odokotela abahlinzayo baziqonde kahle lezi zakhiwo, ikakhulukazi lapho benza ukuhlinzwa kwesifuba noma kwentamo.
Iyini isakhiwo somgudu wesifuba?
Yakhiwe njengepayipi. Ixhunywe kwamanye amapayipi amancane, abizwa ngokuthi ama-lymphatic ducts. Udonga lomsele wesifuba lwakhiwe ngezingqimba ezintathu. Zibizwa ngokuthi i-intima, i-media kanye ne-adventitia. Imisipha ebushelelezi engqimbeni ephakathi (i-media) ihlala ifinyela. Lokhu kugcina uketshezi lwe-lymph luhamba ohlangothini olulodwa, okungukuthi, phezulu.
Futhi, kukhona ama-valve atholakala kulo lonke leli payipi. Lawa ma-valve ayavuleka lapho uketshezi lwe-lymph lukhuphuka, bese luvala uma luzama ukwehla futhi. Lokhu kuvimbela uketshezi lwe-lymph ukuthi lugeleze emuva.
Umsele wesifuba uvame ukuba phakathi kwamasentimitha angu-38 no-45 ubude . Ububanzi bawo buyahlukahluka kuye ngendawo, kusukela kumasentimitha amabili kuya kwangu-5 .
Yiziphi izifo ezingathinta lo msele?
Kunezimo eziningana ezingaphazamisa ukusebenza komsele wesifuba. Lezi akuzona izimo ezivamile ozibona nsuku zonke, kodwa kubalulekile ukuziqaphela.
| Isimo sezokwelapha | Incazelo elula |
|---|---|
| I-Chyle Leak | Uketshezi lwe-lymph olunamafutha, olubizwa ngokuthi 'chyle', luvuza luphuma emgudwini wesifuba luye ezicutshini ezizungezile. Lokhu kuvame ukwenzeka njengenkinga yokuhlinzwa noma ukulimala. |
| I-Chylothorax | Lokhu futhi kuvuza 'okushisayo'. Kodwa lapha ukushisa kuvuza endaweni ezungeze amaphaphu. Lolu uhlobo lwesimo esibizwa ngokuthi i-pleural effusion. Lokhu kungabangela izimpawu ezifana nokuphelelwa umoya, ukuqina kwesifuba, kanye nokukhathala. |
| Ukuvaleka Kwasebuntwini | Umsele wesifuba awukakhiwa ngokuphelele lapho uzalwa. Umsele ungavalwa noma uvalwe ngaphandle kokuxhuma emthanjeni. Lokhu kuvame ukubonakala ezinganeni ezinesifo senhliziyo esibi sokuzalwa. |
Iyini indlela yokwelapha lokhu?
Izinketho zokwelapha zincike esimweni. Udokotela wakho uzonquma ukwelashwa okungcono kakhulu kuwe. Ezinye zezindlela zokwelapha ezivame kakhulu zifaka:
- Izinguquko zesikhashana ekudleni: ikakhulukazi ukushintshela ekudleni okunamafutha aphansi.
- Imithi: Ukunikeza imithi ebhalwe udokotela.
- Inqubo yokususa uketshezi: Uma uketshezi luqongelelene esikhaleni samaphaphu, kufakwa ipayipi ukuze kususwe uketshezi (thoracentesis).
- Ukubopha umsele ngokuhlinzwa: Ukubopha umsele ukuze kumiswe ukuvuza (ukubopha umsele wesifuba).
- Indlela yokuvimba ngamabomu umsele: Indlela yokuvimba ukuvuza ngokuvala umsele ngento ekhethekile (i-thoracic duct embolization).
Uma uzohlinzwa esifubeni noma esiswini sakho, udokotela wakho uzokuchazela ukuthi ngabe kukhona yini ingozi encane noma ebalulekile yokulimala komgudu wesifuba, nokuthi yiziphi izimpawu ongase uzizwe uma wenza kanjalo.
Into ebaluleke kakhulu ukuthi uma ubhekene nobunzima bokuphefumula, ukuqina kwesifuba, noma ukukhathala okungavamile ngemva kokuhlinzwa okunje, kubalulekile ukwazisa udokotela wakho ngokushesha .
Ekugcineni, umgudu wesifuba uyisakhiwo esibalulekile esisisiza sihlale siphilile ngokuthula, ngemuva kwezigcawu, nsuku zonke. Uyipayipi elide eligeleza lisuka esiswini sethu lidlule esifubeni liye entanyeni yethu. Nakuba ungase ucabange ukuthi luhambo olude kangaka, empeleni akuvamile ukuthi lonakale. Futhi uma kwenzeka, odokotela bakulungele ukuyelapha.
Umlayezo Wokuya Nawe Ekhaya
- I-Thoracic Duct iwumsele we-lymphatic omkhulu nobaluleke kakhulu emzimbeni wethu.
- Leli payipi liqoqa uketshezi oluvela emzimbeni wonke (emilenzeni, esiswini, esifubeni, nasohlangothini lwesobunxele lwekhanda) bese lulubuyisela egazini.
- Lokhu kubalulekile ekugcineni ibhalansi yoketshezi emzimbeni kanye nokususa imfucuza.
- Ukulimala kwalokhu akuvamile kakhulu, kodwa izinkinga zingavela ngemva kokuhlinzwa kwesifuba noma kwesisu noma ngenxa yezingozi.
- Uma uba nezimpawu ezifana nobunzima bokuphefumula ngemva kokuhlinzwa esifubeni, bona udokotela wakho ngokushesha.
