Wake waphawula ukuthi ngezinye izikhathi umlenze noma ingalo iyavuvukala kancane? Noma ukuthi uketshezi olufana namanzi lugcwalisa inxeba? Nakuba singacabangi ngakho kakhulu, inethiwekhi emangalisayo yamanethiwekhi emizimbeni yethu ilawula lezi zinto. Kufana nohlelo lokukhipha amanzi edolobheni. Namuhla sizokhuluma ngenye yezingxenye ezincane kakhulu, kodwa ezibaluleke kakhulu zalolo hlelo. Leyo yi-Lymphatic Capillaries.
Kalula nje, ziyini lezi zinhlayiya ze-lymphatic?
Cabanga nje ukuthi umzimba wethu uyidolobha elikhulu. Imithambo yegazi iyimigwaqo emikhulu kulowo muzi. Le migwaqo yilapho umoya-mpilo nezakhamzimba umzimba ozidingayo ziya khona yonke indawo. Kodwa uma lokhu kwenzeka, uketshezi olungadingekile luyakheka phakathi kwamangqamuzana omzimba wethu. Njengoba nje amanzi akheka emigwaqweni lapho lina imvula.
Uhlelo lwe-lymphatic luhlelo olususa yonke leyo mfucuza futhi lugcine umzimba uhlanzekile. Lawa ma-capillary e-lymphatic angamapayipi amancane kakhulu kulolo hlelo. Mancane kakhulu kangangokuthi angangosayizi wezinwele zethu.
Nakuba lezi zifana kancane nama-capillary athwala igazi, kunomehluko omkhulu.
- Ama-capillary e-lymph makhulu kancane ngobubanzi.
- Zivaliwe ngakolunye uhlangothi . Azivuleki kuzo zombili izinhlangothi njengemithambo yegazi.
- Umehluko omkhulu ukuthi uketshezi lungangena kula mapayipi, kodwa uma selungaphakathi, alukwazi ukuphuma futhi.
Lolu hlelo lwe-lymphatic luyingxenye ebaluleke kakhulu yesimiso sethu sokuzivikela komzimba , uhlelo olusivikela ezifweni.
Yiluphi usizo olunikezwa yila mapayipi amancane emzimbeni?
Umsebenzi oyinhloko wama-capillary e-lymphatic ukugcina ibhalansi yoketshezi emzimbeni wethu.
Isikhala esizungeze amaseli ethu sihlala sivuza uketshezi olubizwa ngokuthi uketshezi oluvela kuma-capillaries egazi. Lokhu kuvamile. Kodwa uma lolu ketshezi luvunyelwa ukuthi luqongelelene, lezo zindawo ziqala ukuvuvukala. Lokhu sikubiza ngokuthi ukuvuvukala (i-edema) .
Lokho okwenziwa ama-capillary e-lymphatic ukumunca uketshezi oluthe xaxa oluqongelelekayo. Uma lolu ketshezi lungena ku-capillary ye-lymphatic, silubiza ngokuthi i-lymph .
Kalula nje, ama-capillary e-lymphatic ayisimiso samapayipi amancane asusa "amanzi angcolile" engeziwe aqongelela phakathi kwamaseli omzimba wethu.
Ngokususa uketshezi oluningi bese lufakwa egazini, zisiza futhi ukugcina umfutho wegazi kanye nomthamo wegazi kumazinga ajwayelekile.
Kulungile, ngakho-ke lokhu kusebenza kanjani?
Le nqubo iyamangalisa. Izindonga zama-capillary e-lymphatic zikhethekile kakhulu. Amaseli ayahlangana, akha ama-mini-valve.
- Uma umfutho woketshezi phakathi kwamaseli ukhuphuka, le minyango emincane iyavuleka bese uketshezi lungena ku-capillary.
- Uma ingcindezi engaphakathi kwe-capillary ikhuphuka, le minyango ivala ngokuzenzakalelayo. Ngakho-ke uketshezi olungene ngeke luphinde luphume.
Bese lolu ketshezi lwe-lymph oluqoqiwe luyahamba.
1. Lolu ketshezi oluvela kuma-capillary e-lymphatic luqoqana emithanjeni ye-lymphatic emikhudlwana kancane.
2. Endleleni, lolu ketshezi ludlula ezindaweni zokuhlola ezincane ezibizwa ngokuthi ama-lymph node . Lawa atholakala ezindaweni ezifana nentamo yethu, emakhwapheni, nasezimbotsheni. Lezi zindawo zokuhlola zihlunga izinto ezingafuneki njengamagciwane, amabhaktheriya, kanye namaseli omdlavuza oketshezini.
3. Uketshezi lwe-lymph oluhlungiwe luqoqana emigudwini emikhulu nakakhulu, ikakhulukazi emgudwini wesifuba .
4. Ekugcineni, lolu ketshezi oluhlanziwe lubuyela ohlelweni lokujikeleza kwegazi ngemithambo emikhulu engaphansi kwethambo lethu lentamo ( imithambo ye-subclavian ).
Imizimba yethu ihlala iphilile ngoba lo mjikelezo uyaqhubeka nokusebenza.
Zikuphi izinhlayiya ze-lymphatic emzimbeni?
Le nethiwekhi yamapayipi amancane isakazeke cishe yonke indawo emizimbeni yethu, kodwa kwezinye izindawo ayibonakali.
- Umkantsha
- Uqwanga
- Ingqimba yesikhumba ye-epithelial
Ngaphandle kwalezi zindawo, zonke ezinye izitho zinenethiwekhi yama-capillary e-lymphatic phakathi kwezicubu.
| Izingxenye ze-lymphatic capillary | Umsebenzi owenziwayo |
|---|---|
| Amaseli e-Endothelial | Uhlobo oluyinhloko lweseli olwakha udonga lwe-capillary. Lawa ayagoqeka phezu komunye nomunye ukuze akhe lawo minyango emincane (ama-mini-valve). |
| Ulwelwesi olungaphansi komhlaba | Isebenza njengokusekela lawo maseli. |
| Ama-mini-valve | Ivumela uketshezi ukuthi lungene, kodwa ayivumeli ukuthi luphinde luphume. |
| Imicu yokubambelela | Lezi zifana nezintambo ezincane ezibamba izicubu ezizungeze ama-capillary ndawonye. Lapho izicubu zivuvukala, lezi zintambo ziyanwebeka, okwenza kube lula ukuthi leyo minyango ivuleke futhi ingenise uketshezi. |
Yiziphi izifo ezivamile ezihambisana nalezi?
Uma uhlelo lwe-lymphatic lungasebenzi kahle, izifo ezahlukahlukene zingavela.
| Isimo sezokwelapha | Kalula nje... |
|---|---|
| I-Lymphoma | Lolu uhlobo lomdlavuza oluvela ohlelweni lwe-lymphatic. Kunezinhlobo ezimbili, i-Hodgkin lymphoma kanye ne-non-Hodgkin lymphoma . Lezi zivela kumaseli amhlophe egazi abizwa ngokuthi ama-lymphocyte. |
| Ukuvuvukala (i-Edema) | Ukuvuvukala kwenzeka lapho uketshezi luqoqana phakathi kwezicubu ngokushesha kunokuba uhlelo lwe-lymphatic lungalususa. |
| I-Barava (i-Elephantiasis / i-Lymphatic filariasis) | Ukuvaleka kwesistimu ye-lymphatic kubangela ukuthi uketshezi luqoqeke futhi kubangele ukuvuvukala okungavamile ezingalweni, emilenzeni, noma kwezinye izingxenye zomzimba. |
| I-Lymphangitis | Ukuvuvukala nokutheleleka kwemithambo ye-lymph ngenxa yamagciwane noma amagciwane angena ngokusikeka noma amanxeba. |
| I-Lymphedema | Ukuvuvukala okungapheli kwezingalo noma imilenze ngenxa yomonakalo ohlelweni lwe-lymphatic (isb., ngenxa yokuhlinzwa, ukwelashwa ngemisebe) okuvimbela uketshezi lwe-lymph ukuthi lugeleze kahle. |
Ziyini izimpawu zenkinga yesistimu ye-lymphatic?
Uma unezimpawu ezinjengalezi, kungaba yinkinga ohlelweni lwakho lwe-lymphatic.
- Ukukhathala ngaphandle kwesizathu
- Umkhuhlane kanye nokubanda
- Ubuhlungu besisu
- Ama-lymph node avuvukele (amaqhubu entanyeni, emakhwapheni, nasesinqeni)
- Ukwehlisa isisindo ngaphandle kwesizathu
- Ubunzima bokuphefumula noma ukuhamba
- Ukuvuvukala (ikakhulukazi ezandleni nasezinyaweni)
Sigcina kanjani uhlelo lwethu lwe-lymphatic luphilile?
Kunezinto ezimbalwa ezilula esingazenza ukuze sigcine uhlelo lwethu lokukhipha amanzi oluhle lusesimweni esihle.
- Phuza amanzi amaningi: Gcina umzimba wakho unamanzi anele ukuze uketshezi lwe-lymph lukwazi ukuhamba kalula kuwo wonke umzimba.
- Yidla ukudla okunempilo: Yamukela ukudla okunempilo.
- Ukuzivocavoca: Zibekele okungenani imizuzu eyi-150 yokuzivocavoca okunamandla aphakathi ngesonto. Ukuhamba, ukugijima, noma ukugibela ibhayisikili konke kuyizinketho ezinhle. Uma uzivocavoca, imisipha yakho iyafinyela, okusiza ukuhambisa uketshezi emzimbeni wakho.
- Gcina isisindo esinempilo: Ukulawula isisindo somzimba kubaluleke kakhulu ohlelweni lwe-lymphatic.
- Gwema amakhemikhali anobuthi: Nciphisa ukuchayeka kwakho ezintweni ezifana nezibulala-zinambuzane kanye nezihlanzi eziqinile ngangokunokwenzeka.
- Uma uthola inxeba: Gcina inxeba lihlanzekile futhi ulivimbele ukuthi lingangenwa yigciwane. Uma usola ukuthi kukhona ukutheleleka, bona udokotela ngokushesha.
Kunini lapho udinga ukubonana nodokotela?
Izinto ezifana nokuhlolwa minyaka yonke zingakusiza ukuthi ubone izinkinga kusenesikhathi. Kodwa-ke, uma unezimpawu ezinjengalezi, ungalindi isikhathi eside bese ubona udokotela wakho ngokushesha.
- Ukusikeka noma amanxeba angapholi ngokushesha.
- Ukukhathala okukhulu okuhlala isikhathi esingaphezu kwamasonto ambalwa.
- Ukuvuvukala okungenasizathu esicacile, okuhlala amasonto amaningana, noma okuphazamisa imisebenzi yansuku zonke.
Ungazinaki lezi zimpawu. Uma isifo se-lymphatic system sitholakala ngokushesha, kuba lula ukwelapha. Uma kudingeka, udokotela wakho uzokuthumela ukuze uyohlolwa njengokuhlolwa kwegazi, i-CT scan , i-MRI , noma i-Doppler ultrasound .
Umlayezo Wokuya Nawe Ekhaya
- Ama-capillary e-lymphatic ayingxenye ebaluleke kakhulu "yohlelo lokuhlanza" lomzimba wethu, kodwa esingawanaki kakhulu.
- Ukuvuvukala (i-edema) emzimbeni, ikakhulukazi ezandleni nasezinyaweni, kungaba uphawu olukhulu olubonisa inkinga ohlelweni lwe-lymphatic.
- Ukuphuza amanzi amaningi, ukuzivocavoca njalo, nokugcina isisindo esinempilo kubalulekile ekugcineni uhlelo lwakho lwe-lymph luphilile.
- Uma uvuvukile ngendlela engachazeki, ukhathele kakhulu, noma amanxeba angapholi, ungalokothi ungakunaki lokho bese ubona udokotela wakho ngokushesha.
