Singathetha nje ngemithambo yegazi emizimbeni yethu: Imithambo yegazi kunye nemithambo yegazi?

Ngaba wakha wazibuza ukuba eli gazi lihamba njani lisiya naphambili emizimbeni yethu? Cinga nje, njengeendlela ezikwisixeko esikhulu, imizimba yethu ikwanayo nendlela ekhethekileyo yokuthwala igazi. Ezi ndlela zibizwa ngokuba yimithambo yegazi, ezibaluleke kakhulu kubomi bethu nakwimpilo yethu. Ngoko ke namhlanje, masithethe ngokulula malunga nokuba le mithambo yegazi kunye nemithambo yegazi zibaluleke kangakanani, ukuba zibaluleke kangakanani emizimbeni yethu, kunye nento esinokuyenza ukuze sizigcine ziphilile.

Yintoni le 'nkqubo yegazi' emizimbeni yethu? (Inkqubo yokujikeleza kwegazi)

Ngamafutshane, sibiza oku ngokuthi yinkqubo yokujikeleza kwegazi . Oku kufana 'nenkonzo yothutho' enamandla kakhulu emzimbeni wethu. 'Injini' ephambili yale nkonzo yintliziyo yethu. Igazi elimpontshwa yintliziyo lihamba emzimbeni wonke 'ngeendlela' ezibizwa ngokuba yimithambo yegazi kunye nemithambo yegazi.

Cinga nje, eli gazi lilo elithwala ioksijini kunye nezondlo ezifunwa yiseli nganye emzimbeni wethu, njengokuzisa ukutya ekhaya. Kwakhona, le 'mithambo yegazi' ikwathwala nenkunkuma engafunekiyo eveliswa ziiseli, njengekhabhoni dayoksayidi . Ngoko ke ngoku ungabona ukuba kubaluleke kangakanani ukuba le nkqubo isebenze ngokufanelekileyo, akunjalo?

Zithini ii-Arteries? – ‘Iindlela eziphambili’ ezihamba zisuka entliziyweni emzimbeni wonke

Kulungile, masiqale sijonge ukuba yintoni imithambo yegazi. Ngamafutshane, imithambo yegazi yimithambo yegazi ethwala igazi elicocekileyo, elineoksijini ukusuka entliziyweni ukuya kuzo zonke iindawo zomzimba (ngaphandle komthambo omnye okhethekileyo, esiza kuthetha ngawo kamva). Zifana 'neendlela eziphambili' zesixeko, ezithwala igazi ukusuka 'kwiziko lesixeko', intliziyo, ngesantya esiphezulu. Igazi elikwimithambo yegazi lidla ngokuba bomvu kuba lineoksijini engaphezulu.

Iindonga zale mithambo yegazi zijiyile kwaye zinamandla kunezo zemithambo yegazi. Oku kungenxa yokuba kufuneka zimelane noxinzelelo oluphezulu oludalwa yintliziyo xa ipompa igazi. Cinga ngayo njengombhobho othwala amanzi kwi-tank yamanzi. Umthambo omkhulu emzimbeni wethu yi -aorta . Kulapho igazi lisasazwa khona kweminye imithambo yegazi emincinci, ebizwa ngokuba yi-arterioles .

Kuthekani ukuba unengxaki ngemithambo yakho yegazi?

Nangona kunjalo, kwanale 'ndlela ziphambili' inokuba neengxaki. Ingxaki ephambili kukuqina nokuncitshiswa kweendonga zemithambo yegazi, ezaziwa ngokuba yi-atherosclerosis . Oku kwenzeka xa i-cholesterol engafunekiyo kunye namafutha avela ekutyeni esikutyayo eqokelelana kwimithambo yegazi njenge -'plaque' , ithintela ukuhamba kwegazi. Kufana nomhlwa oqokelelana ngaphakathi kombhobho wamanzi omdala.

Kwenzeka ntoni ukuba oku kuyenzeka? Imithambo yegazi ehambisa igazi entliziyweni (ebizwa ngokuba yimithambo yegazi yentliziyo ) inokuvaleka, okubangela ukuhlaselwa yintliziyo . Ukuba imithambo yegazi ethwala igazi ebuchotsheni iyavaleka, okubangela isifo sohlangothi , kunokubangela noxinzelelo lwegazi oluphezulu .Imithambo yegazi nayo ingonakala.
