Masifunde ngakumbi ngee-capillaries? Imithambo yegazi emincinci emzimbeni wakho!

Ngaba wakha wazibuza ngemithambo yegazi emincinci engaphakathi emizimbeni yethu? Yiloo nto siyibiza ngokuba zii-capillaries . Zifana nemisonto emincinci ehamba emizimbeni yethu. Ukubaluleka kwazo akunakugqithiswa. Namhlanje, siza kuthetha ngokuba zezi capillaries ziyintoni, zenzani, ziziphi izifo ezibangelayo, kunye nendlela yokuzigcina ziphilile.

Zithini ii-capillaries? Masiqonde ngokulula!

Ngamafutshane, ii-capillaries zimithambo yegazi emincinci ehamba emzimbeni wakho. Zifana neetyhubhu ezincinci apho igazi lihamba khona. Umsebenzi wazo ophambili kukuthwala izondlo kunye neoksijini ukuya kwiiseli ezikwizitho zomzimba wakho kunye neenkqubo zomzimba. Zikwathwala nenkunkuma, efana nekhabhoni diokside , evela kwezo seli.

Cinga ngale ndlela. Kufana nomntu ozisa izinto ezininzi endlwini yakho aze athathe yonke inkunkuma. Oku kwenzeka emzimbeni wakho wonke, kwiindawo ezahlukeneyo. Akumangalisi na?

Ngaba kukho iintlobo zee-capillaries?

Ewe, ii-capillaries nazo zinemilo eyahlukeneyo ngokuxhomekeke kwimisebenzi eziyenzayo. Singachonga iintlobo ezintathu eziphambili:

1. Ii-capillaries ezihlala ziqinile: Ezi zinemingxuma emincinci (i-fenestrae) , okanye imingxunya. Oku kuvumela ukutshintshiselana kwezinto ngokukhawuleza. Ungazibona ezi ntlobo zee-capillaries kwizintso zakho, emathunjini amancinci, nakwii-endocrine glands .

2. Ii-capillaries ezingapheliyo ezingenamaqhuqhuva: Ziisuntswana ezincinci kakhulu kuphela ezinokudlula eludongeni lwezi ntlobo zee-capillaries. Ezi zifumaneka kwinkqubo yakho yemithambo-luvo, kunye nakwizicubu zamafutha kunye nezicubu zemisipha.

Kwenzeka ntoni kwii-capillaries? Yintoni kanye kanye umsebenzi wazo?

Ii-capillaries zezona zinto zigqibezela inkqubo yethu yokujikeleza kwegazi. Oko kukuthi, imithambo yegazi kunye nemithambo yegazi zidibene ngezi capillaries. Uyazi, imithambo yegazi ithwala igazi elineoksijini eninzi ukusuka entliziyweni ukuya kwizitho zomzimba. Imithambo yegazi ithwala igazi elingenaoksijini kunye nemveliso engcolileyo evela kwizitho zomzimba ibuyela entliziyweni.

Ngoko ke umsebenzi wee-capillaries kukusebenza njengendawo apho izinto ezivela kwimithambo yegazi kunye nemithambo yegazi zitshintshiselana khona . Nangona imithambo yegazi kunye nemithambo yegazi zithwala iigesi kunye nezondlo emzimbeni wonke, zezi capillaries zizihambisa kwiindawo zazo ezicwangcisiweyo, eziziiseli. Kubaluleke kakhulu, akunjalo?

Ii-capillaries zinceda amalungu amaninzi kunye neenkqubo ezahlukeneyo emzimbeni wethu. Umzekelo:

• Umongo wethambo: Unceda iiseli zegazi ezisandula ukwakheka ukuba zingene egazini.
• Ubuchopho: Nangona bubonelela ngesondlo engqondweni, bunceda ekwenzeni umqobo wegazi-ubuchopho, othintela izinto ezinobungozi ukuba zingangeni.
