Umzimba wethu ufana nomatshini omangalisayo, akunjalo? Inkqubo yeendlela ezinkulu ngaphakathi komatshini yimithambo yegazi yethu. Nangona sivile ngeendlela ezinkulu ezifana nemithambo yegazi kunye nemithambo yegazi, ubusazi ngenethiwekhi yeendlela ezincinci nezincinci ezikwicala kule nkqubo ezingabonakali ngamehlo enyama? Ezi sizibiza ngokuba zii-capillaries. Namhlanje siza kuthetha ngohlobo olukhethekileyo lwe-capillary, uhlobo lwe-capillary oluneefestile ezincinci.
Zithini ezi capillaries 'ezinefestile' (iiFenestrated Capillaries)?
Ngamafutshane, ezi luhlobo lwe-capillary kwinkqubo yethu yemithambo yegazi enemingxuma emincinci kakhulu okanye imingxuma efana neefestile. Igama elithi "fenestrae" ngesiLatini lithetha "iifestile," ngoko ke igama livela kuloo ntsingiselo.
Endaweni yokuvumela izinto ukuba zidlule kwii-capillaries eziqhelekileyo, ezi capillaries 'zineefestile' zinokuvumela amasuntswana amakhulu, anjengeeproteni, ukuba adlule egazini aye kwizitho zomzimba kunye namadlala. Cinga ngayo njengokusebenzisa i-mesh enemingxuma emikhulu kancinci endaweni ye-mesh eqhelekileyo. Oku kuvumela ukutshintshiselana kwezinto ngendlela esebenza ngcono nangokukhawuleza.
Yintoni eyona nto iphambili kwezi zinto? Kutheni zibaluleke kangaka?
Ezi capillaries zinceda ekuthuthweni kwegazi, ulwelo, kunye nenkunkuma emzimbeni wonke, kodwa owona msebenzi wazo ubalulekileyo kukusebenza kwezintso .
Cinga ngezintso zethu njengeyona nkqubo yokucoca iphucukileyo emzimbeni. Inxalenye ephambili yesi sihluzo ibizwa ngokuba yi-glomerulus . Le glomerulus ayiyonto ingaphezulu kwebhola encinci yentambo eyenziwe ngala makhapha aneefestile esithethe ngawo. Ifana nesihluzo seti.
Njengoko igazi lidlula kule bhola yomsonto, inkunkuma kunye namanzi angaphezulu ahluzwa ngezo festile zincinci. Nangona kunjalo, izinto ezinkulu ezifunekayo emzimbeni, ezinje ngeeproteni kunye neeseli ezibomvu zegazi, zihlala egazini. Inkunkuma ehluzwa ngale ndlela ikhutshwa emzimbeni njengomchamo.
Ngaba uyaqonda? Izintso zethu ziyakwazi ukucoca igazi ngokufanelekileyo kwaye zisuse inkunkuma ngenxa 'yeefestile' ezikhethekileyo kwezi Fenestrated Capillaries.
Ezi capillaries zikwajikeleza ii-renal tubules. Ngazo, izondlo ezifunwa ngumzimba kwizinto ezihluziweyo zibuyiselwa egazini. Ke ngoko, zibalulekile ekusebenzeni kakuhle kwezintso.
Ziphi ezi zinto emzimbeni wethu?
Ezi capillaries zikhethekileyo zifumaneka kwiindawo apho imetabolism yomzimba kufuneka yenzeke ngokukhawuleza nangokufanelekileyo. Makhe sijonge ukuba zeziphi ezo ndawo zibalulekileyo.
| Isitho somzimba/indlala | Umsebenzi owenziwa apho |
|---|---|
| Izintso | Ukucoca inkunkuma egazini nokuvelisa umchamo. |
| Amathumbu Amancinci | Ukufunxwa kwezondlo ekutyeni esikutyayo zingene egazini. |
| I-Pancreas | Ukukhupha ii-enzymes kunye nee-hormones ezifana ne-insulin egazini ezifunekayo ekugayweni kokutya. |
| Ii-Endocrine Glands | Ukukhululwa kweehomoni egazini ezilawula izinto ezifana neemvakalelo zethu nokukhula kwethu. |
Ziziphi izifo ezichaphazela la ma-capillaries?
Xa le mithambo yegazi mincinci yonakele, ukusebenza kwamalungu anxulumene nayo kunokuchaphazeleka ngokuthe ngqo.
Izifo zezintso
Abantu abaneSifo sezintso esingapheliyo (CKD) banokuba nomonakalo kwezi capillaries. Ngokukodwa, uthungelwano lwee capillaries ezijikeleze ii-renal tubules lunokuba luncinci kwaye lungabi lukhuni kangako. Oku kubizwa ngokuba yi-'capillary rarefaction'. Xa oku kusenzeka, izintso azikwazi ukusebenza kakuhle kwaye ezinye iingxaki zempilo ezifana noxinzelelo lwegazi oluphezulu (iHypertension) zinokwenzeka.
Kwakhona, izifo ezifana ne -glomerulonephritis , ukudumba kwe-glomeruli, zinokuphazamisa yonke inkqubo yokuhluza izintso. Ukuba ezi zifo zezintso azinyangwa ngokukhawuleza, zinokuqhubeka nokungasebenzi kakuhle kwezintso.
Imeko engaqhelekanga kodwa enzima kakhulu
I-Systemic Capillary Leak Syndrome (SCLS)Le yimeko engaqhelekanga kakhulu kwaye inokuba yingozi ebomini. Oku kwenzeka xa iindonga zee-capillaries zonakele, nto leyo ebangela ukuba ulwelo oluninzi luphume kwimithambo yegazi luye kwizicubu ezingqongileyo. Oku kunokubangela ukuba uxinzelelo lwakho lwegazi luhle ngequbuliso luye kwinqanaba eliphantsi kakhulu. Kodwa khumbula, le yimeko engaqhelekanga kakhulu.
Ngoko ke singayigcina njani le mithambo yegazi incinci isempilweni?
Akukho nto ikhethekileyo yokwenza ngale nto. Eyona nto ingcono kukugcina impilo entle iyonke. Kuba la ma-capillaries ayinxalenye yenkqubo yethu yokujikeleza kwegazi. Ngoko ke ukuba yonke inkqubo iphilile, la ma-vein amancinci nawo aphilile.
Nazi ezinye izinto onokuzenza:
- Zilolonge rhoqo: Ziqhelise ubomi obusempilweni.
- Yitya ukutya okunesondlo: Yitya iziqhamo nemifuno emininzi. Nciphisa utywala. Khetha ukutya okunempilo kwintliziyo.
- Gcina ubunzima obusempilweni: Gcina ubunzima obufanele ubude bakho. Ukuba utyebile kakhulu, zama ukunciphisa umzimba.
- Lawula izifo ezingapheliyo: Ukuba unezifo ezifana nesifo seswekile okanye uxinzelelo lwegazi oluphezulu, zilawule kakuhle ngokwemiyalelo kagqirha wakho.
- Kuphephe ukutshaya ngokupheleleyo: Ukutshaya kuyingozi kakhulu kwimithambo yegazi.
Ndifanele ndimbone nini ugqirha?
Kubaluleke kakhulu ukubona ugqirha wakho wosapho ukuba ubona naluphi na utshintsho emzimbeni wakho, ingakumbi ukuba uneempawu ezinokuba zinxulumene nesifo sezintso.

Umyalezo Wokuya Ekhaya
- Ii-capillaries ezine-fenestrated luhlobo lwemithambo yegazi ecolekileyo kakhulu esebenza njengenkqubo ekhethekileyo yokucoca emzimbeni wethu.
- Ezi zinto zibalulekile ekusebenzeni kakuhle kwezintso zethu, amathumbu, kunye nenkqubo yamahomoni.
- Eyona ndlela ilungileyo yokugcina ezi zinto zisempilweni kukunyamekela impilo yakho iyonke. Oko kuthetha ukutya kakuhle, ukuzilolonga, kunye nokugcina indlela yokuphila esempilweni.
- Qaphela iimpawu ezinokuthi zinxulumene nesifo sezintso. Ukuba unamathandabuzo, ungalibazisi ukubona ugqirha wakho.
