Masifunde ngamaqhawe amancinci emzimbeni wakho - iiLymphatic Capillaries.

Ngaba wakha wazibuza ukuba zingaphi izinto ezimangalisayo ezenzekayo ngaphakathi emizimbeni yethu singazi nokuba zinjani? Namhlanje siza kuthetha ngee-lymphatic capillaries, okanye ngesiNgesi `(Lymphatic Capillaries)`, ezisisebenzela ngokuzolileyo njengeeqhawe ezincinci. Usenokuba awukaze uve ngeli gama, kodwa inkonzo aba bantu abayenzayo ukugcina imizimba yethu isempilweni iyamangalisa.

Zithini ezi capillaries ze-lymphatic? Kutheni zibaluleke kangaka?

Ngamafutshane, ii-lymphatic capillaries zinethiwekhi yee-channels ezincinci nezithambileyo ezihamba emizimbeni yethu. Ezinye zazo zincinci njengentambo yeenwele zethu. Ngaba ukhe weva ngemithambo yegazi, okanye ii-capillaries zegazi? Ziyafana, kodwa zinomahluko ambalwa. Ezi capillaries ze-lymphatic zivaliwe kwelinye icala, njengebhegi encinci. Olunye uphawu kukuba ulwelo lunokungena kwezi tshaneli, kodwa alunakuphuma, njengocango oluvula indlela enye kuphela.

Le nkqubo incinci yemijelo yeyombutho wethu we-lymphatic. Le nkqubo ye-lymphatic yinxalenye ebaluleke kakhulu 'yenkqubo yethu yokuzikhusela'. Inkqubo yokuzikhusela isebenza njengomkhosi wokhuselo lomzimba wethu. Ngoko ke, ii-capillaries ze-lymphatic zifana namajoni aqeqeshwe ngokukodwa kulo mkhosi wokhuselo. Umsebenzi wawo ophambili kukuqokelela ulwelo olongezelelweyo, olubizwa ngokuba yi-'lymph', oluqokelelana kwiindawo ezahlukeneyo zomzimba wethu kwaye lulawuleke ngokufanelekileyo.

Zeziphi iinkonzo ezibonelelwa zii-lymphatic capillaries emizimbeni yethu?

Umsebenzi owenziwa zezi ndlela zincinci mkhulu kakhulu, ukuba sithetha ngokuchanekileyo:

1. Ukugcina ulungelelwano lolwelo emzimbeni: Ulwelo olongezelelweyo oluqokelelana kwiiseli zethu, olubizwa ngokuba yi-'interstitial fluid', lufunxwa zezi lymphatic capillaries. Olu lwelo lufunxwayo lubizwa ngokuba yi-'lymph'.

2. Ulawulo loxinzelelo lwegazi kunye nomthamo: Oku kunceda ukugcina uxinzelelo lwethu lwegazi kunye nomthamo ulawulwa ngokongeza i-lymph kwinkqubo yethu yokujikeleza kwegazi.

3. Ukuthintela ukudumba: Ezi capillaries ze-lymphatic zikwanceda ekuthinteleni ukudumba (i-edema) ukuba kungaqokeleleki kwiindawo ezahlukeneyo zomzimba. Cinga nje ukuba imibhobho engaphakathi endlwini yethu ibingasebenzi kakuhle, amanzi ebeya kuqokelelwa aze azalise igadi.

Ayimangalisi na le nkqubo incinci yetshaneli?

Le yindlela entsonkothileyo kakhulu, kodwa intle kakhulu. Cinga ngayo ngolu hlobo.

Iindonga zee-lymphatic capillaries zikhethekile kakhulu. Ulwelo lungangena ngazo, kodwa alunakuphinda luphume. Ngoko ke, xa ulwelo olongezelelweyo phakathi kweeseli lutsalwa kwezi ndlela, uxinzelelo olungaphakathi kwendlela luyanda kancinci kancinci. Kungenxa yolo xinzelelo apho i-lymph isiya phambili, oko kukuthi, ukuya entliziyweni yethu.

Nantsi into eyenzekayo kolu hambo:

• Okokuqala, i-lymph iqokelelwa kwezi capillaries zincinci ze-lymphatic ize idluliselwe kwimithambo ye-lymphatic emikhulu kancinci.
• Ezi `mithambo ye-lymphatic` ziyadibana ukuze zenze 'imijelo yokuqokelela' emikhulu nangakumbi. Ngaphakathi kwezi misele kukho 'iivalvu' ezincinci, ezifana neengcango. Ezi 'valvu' zivumela kuphela 'i-lymph' ukuba ihambe kwicala elinye, kungekhona kwelinye icala.
• Okulandelayo, i-lymph evela kwezi 'ducts collecting' ijoyina 'i-lymphatic duct' yasekunene okanye yasekhohlo. Oku kukwabizwa ngokuba yi-'thoracic duct'.
• Ukusuka kwezi lymphatic ducts, i-lymph ingena kwimithambo yegazi emikhulu ebizwa ngokuba yi-subclavian veins entanyeni yethu.
• Le mithambo idibana ukuze yenze umthambo wegazi omkhulu kakhulu obizwa ngokuba yi-vena cava ephezulu.
• Okokugqibela, yi-vena cava ebuyisela ulwelo lwe-lymphatic olucociweyo egazini lethu.

Ngeli xesha lohambo, i-lymph idlula kwii-lymph nodes emzimbeni wethu. Njengesihluzo sethu samanzi, ezi lymph nodes zihluza zize zicoce i-lymph kwizinto ezingafunekiyo, ezifana neentsholongwane. Kulapho ke i-lymph ecocekileyo ibuyiselwa egazini. Ayisiyonkqubo imangalisayo na le?

Ziphi emzimbeni wethu ezi capillaries ze-lymphatic?

Ungamangaliswa kukufumanisa ukuba zifumaneka phantse kuyo yonke indawo emizimbeni yethu! Ngokuchanekileyo, zifumaneka kakhulu kwiindawo eziphakathi kweeseli zethu (indawo ethi "interstitial space"). Zifumaneka kwizicubu zelungu ngalinye emzimbeni wethu. Nangona kunjalo, kukho iindawo ezimbalwa apho zingafumaneki khona. Ezi "ziithambo" kunye nezicubu ezingenayo imithambo yegazi. Umzekelo, azifumaneki "kwi-cartilage" yethu (inxalenye ethambileyo phakathi kwamathambo) kunye nomaleko we-"epithelial" phezu kolusu.

Zithini iindawo ze-lymphatic capillary? Yinto yesayensi encinci, kodwa kufanelekile ukuyazi!

Le channel incinci yenziwe ngamacandelo aliqela aphambili:

• Iiseli ze-Endothelial: Ezi zezona zinto zakha iindonga zee-capillaries. Zibekwe enye phezu kwenye, njengezitena.
• `I-basement membrane`: Yile nto ixhasa `ii-endothelial cells` kwaye izigcine zisendaweni yazo.
• `Iivalufa ezincinci`: Sele sithethe ngazo ngaphambili. Zivumela kuphela ulwelo ukuba lungene, hayi ukuba luphume.
• Iintambo ezibambelelayo: Ezi zifana nemisonto emincinci. Zidibanisa iiseli ze-endothelial kwizicubu ezijikelezileyo. Ziyanwebeka.

Zibukeka njani ezi zinto? Ngaba zibukeka njengeenwele ngokwenene?

Ewe, ithambile kakhulu. I-lymphatic capillary ifana netyhubhu. Ububanzi bayo, oko kukuthi, ubukhulu bayo, bumalunga nama-50 micrometer. Oko kuphantse kube bukhulu bomsonto weenwele zethu. Elinye icala lale tyhubhu livaliwe, njengemilo yegqabi lom-oki.

Iindonga zezi zincinci kakhulu, zinobukhulu beseli enye kuphela. Ngenxa yokuba iiseli zibekwe phezu kwenye, "ulwelo oluphakathi" lungena lula kwi-capillary.

Ezi zifana kancinci nemithambo yethu, imithambo yegazi ethwala igazi. Enyanisweni, njengemithambo, ulwelo luhamba kwicala elinye kuphela kwi-lymphatic capillaries. Kwaye zombini zinodonga olubhityileyo.

Zeziphi izifo eziqhelekileyo ezichaphazela ii-lymphatic capillaries? Masiqaphele oku!

Nokuba bubuthathaka okanye yingxaki ethile, kukho izifo ezininzi ezinokuchaphazela ezi capillaries ze-lymphatic. Ezinye zazo zezi:

• I-Hodgkin lymphoma kunye ne-non-Hodgkin lymphoma: Ezi ziintlobo ezimbini zomhlaza ezikhula kwinkqubo ye-lymphatic. Ziqala kwiiseli ezimhlophe zegazi ezibizwa ngokuba zii-lymphocytes.
• Ukudumba: Sele sithethe ngale nto ngaphambili. Ukudumba kwenzeka xa ulwelo olungaphakathi luqokelelana kwizicwili ngokukhawuleza kunokuba lunokususwa emzimbeni.
• I-Elephantiasis / i-lymphatic filariasis: Usenokuba ukhe weva ngale nto. Xa inkqubo ye-lymphatic ivalekile, ulwelo lwe-lymphatic luyaqokelelana luze lubangele ukudumba kwiindawo ezahlukeneyo zomzimba, ingakumbi iingalo, imilenze, kunye namalungu esini.
• I-Lymphangitis: Ukudumba kwemithambo ye-lymphatic okubangelwa linxeba, ukunqunyulwa, okanye usulelo olubangelwa ziintsholongwane okanye iibhaktheriya.
• I-Lymphedema: I-lymph egqithisileyo iqokelelana kwizicubu ezithambileyo zomzimba, ingakumbi iingalo nemilenze, nto leyo ebangela ukudumba. Esi sisifo esihlala ixesha elide nesingapheliyo. Sidla ngokuphathwa ngaphandle kotyando.
