Chii chinonzi venous system?

Midziyo rudzi rwemudziyo weropa unodzosera deoxygenated ropa kubva kunhengo dzako kudzokera pamoyo wako. Izvi zvakasiyana netsinga dzako, dzinounza ropa rakafemerwa kubva pamoyo wako kuenda kune mumwe muviri wako wese.

Ropa rakagadzirwa neoxygenated iro rinoyerera kupinda mutsinga dzako rinounganidzwa mukati memidziyo midiki yeropa inonzi capillaries. MaCapillaries ndiwo madiki eropa mumuviri wako. Oxygen inopfuura nepakati pemadziro e capillaries ako kumatumbu ako. Carbon dioxide inogona zvakare kufamba mukati mako capillaries kubva munyama usati wapinda mutsinga dzako.

Iyo venous system inoreva kunetiweki yetsinga dzinoshanda kudzosera deoxygenated ropa kudzokera kumoyo wako.

Tsinga mamiriro

Iwo madziro etsinga dzako akaumbwa nematatu matatu akasiyana:

• Tunica kunze. Uyu ndiwo mupendero wekunze wemadziro etsinga, uye zvakare wakakora. Inonyanya kugadzirwa neyekubatanidza matissue. Iyo tunica externa zvakare ine tudiki tsinga dzeropa dzinodaidzwa kuti vasa vasorum iyo inopa ropa kumadziro etsinga dzako.
• Tunica midhiya. Iyo tunica midhiya ndiyo yepakati layer. Iyo yakatetepa uye ine hombe yakawanda ye collagen. Collagen ndechimwe chezvinhu zvikuru zvezvinhu zvinobatana.
• Tunica intima. Uyu ndiwo mukatikati memukati. Icho chidimbu chimwe chete chemasero endothelium uye mamwe matishu anobatana. Rukoko urwu dzimwe nguva rune mavhavha enzira imwe, kunyanya mutsinga dzemaoko ako nemakumbo. Mavharuvhu aya anodzivirira ropa kubva kuyerera richidzokera kumashure.

Mhando dzetsinga

Tsinga dzinowanzo kuverengerwa zvichienderana nenzvimbo yadzo uye chero yakasarudzika maficha kana mabasa.

Pulmonary uye systemic mutsinga

Muviri wako unotenderera ropa munzira mbiri dzakasiyana dzinodaidzwa kuti systemic wedunhu uye yemapapu wedunhu. Tsinga dzinoenderana nedunhu ravanowanikwa mu:

• Tsinga dzemapapu. Iyo pulmonary redunhu inotakura deoxygenated ropa kubva pamoyo wako kuenda kumapapu ako. Kana mapapu ako akaisa oxygen muropa, iyo pulmonary redunhu inoidzosa kumoyo wako. Kune mitsipa mina yemapapu. Ivo vakasarudzika nekuti vanotakura oxygenated ropa. Mimwe tsinga dzinotakura chete deoxygenated ropa.
• Tsinga dzakarongeka. Iyo systemic wedunhu inotakura deoxygenated ropa kubva kune yakasara yemuviri ichidzokera pamoyo wako, uko iyo inopinda mukati mepulmonary redhiyo yeoksijeni. Mazhinji tsinga ane systemic tsinga.

Tsinga dzakadzika uye tsinga dzepamusoro

Masystemic veins anowedzeredzwa seanogona kunge ari:

• Tsinga dzakadzika. Izvi zvinowanikwa mumhasuru kana pamwe nemapfupa. Iyo tunica intima yeakadzika mutsinga kazhinji ine imwe-nzira vharuvhu yekudzivirira ropa kubva kuyerera richidzokera kumashure. Tsandanyama dzepedyo dzinomanikidzawo mutsinga wakadzika kuti ropa rifambe kuenda kumberi.
• Tsinga dzepamusoro. Izvi zvinowanikwa munzvimbo ine mafuta pasi peganda rako. Iyo tunica intima yechipenga chetsinga inogona zvakare kuve neyese-nzira vharuvhu. Nekudaro, pasina mhasuru iri padyo yekumanikidza, vanowanzo fambisa ropa zvishoma nezvishoma kupfuura zvinoita mutsinga dzakadzika.
• Kubatanidza tsinga. Ropa kubva mutsinga dzepamusoro rinowanzoendeswa mukati mevhegi dzakadzika kuburikidza netsinga pfupi dzinonzi dzinobatanidza tsinga. Mavharuvhu ari mutsinga idzi anotendera ropa kuyerera kubva mutsinga dzepamusoro kusvika mutsinga dzako dzakadzika, asi kwete imwe nzira.

Venous system dhayagiramu

Shandisa iyi inofambidzana 3-D dhayagiramu yekuongorora iyo venous system.

Ndeapi mamiriro ezvinhu anokanganisa venous system?

Mamiriro mazhinji anogona kukanganisa yako venous system. Zvimwe zvezvinhu zvakajairika zvinosanganisira:

• Yakadzika vein thrombosis (DVT). Ropa rinovhara muropa mukati mutsinga yakadzika, kazhinji mugumbo rako. Iri banga rinogona kuenda kumapapu ako, zvichikonzera pulmonary embolism.
• Yekunze thrombophlebitis. Mutsinga unopisa wepamusoro, kazhinji mugumbo rako, unobva waita ropa rinovhara. Nepo iyo clot inogona kupota ichienda kune yakadzika tsinga, ichikonzera DVT, thrombophlebitis kazhinji haina kudzikira zvakanyanya kupfuura DVT.
• Varicose tsinga. Zvepamusoro zvetsinga padyo nechepamusoro peganda zvinoonekwa kuzvimba. Izvi zvinoitika kana mavhavha enzira imwe chete adonha kana kuti tsinga madziro, zvoita kuti ropa riyerere richidzokera kumashure.
• Chisingaperi venous insufficiency. Ropa rinounganidza mune zvepamusoro uye zvakadzika mutsinga dzemakumbo ako nekuda kwekusakafanira kushanda kweimwe-nzira mavharuvhu. Ipo yakafanana nevevaricose veins, kusingaperi venous insufficiency inowanzo kukonzera zvimwe zviratidzo, kusanganisira zvakasviba ganda kugadzirwa uye maronda mune zvimwe zviitiko.

Ndezvipi zviratidzo zvehutachiona mamiriro?

Kunyange zvazvo zviratidzo zvehutachiona zvinogona kusiyana zvakasiyana, zvimwe zvinowanzoitika zvinosanganisira:

• kuzvimba kana kuzvimba
• unyoro kana kurwadziwa
• tsinga dzinonzwa kudziirwa kusvika pakubata
• kupisa kana kuchenesa

Zviratidzo izvi zvinonyanya kuwanikwa mumakumbo ako. Kana iwe ukacherekedza chero cheizvi uye zvikasavandudzika mushure memazuva mashoma, ita musangano nachiremba wako.

Ivo vanogona kuita venography. Mune maitiro aya, chiremba wako anopinza musiyano kufa mukati mutsinga dzako kuti ubudise X-ray mufananidzo wenzvimbo yakati.

Matipi etsinga dzine hutano

Tevedza aya matipi ekuchengetedza yako vein madziro uye mavhavha akasimba uye achishanda nemazvo:

• Gara uchiita maekisesaizi kuti ropa rifambe mukati metsinga dzako.
• Edza kuchengetedza huremu hune hutano, izvo zvinoderedza njodzi yako yekukwira kweropa. Kuwedzera kweropa kunogona kutapudza tsinga dzako nguva yekuwedzera nekuda kwekuwedzera kumanikidza.
• Dzivisa nguva refu yekumira kana kugara. Edza kuchinja chinzvimbo nguva dzose mukati mezuva.
• Paunenge ugere pasi, dzivisa kuyambuka makumbo ako kwenguva yakareba kana kugara uchichinja zvinzvimbo kuitira kuti rimwe gumbo risati riri pamusoro kwenguva refu.
• Paunenge uchibhururuka, inwa mvura yakawanda uye edza kumira uye kutambanudza kakawanda sezvinobvira. Kunyangwe ugere, iwe unogona kushandura makumbo ako kukurudzira kuyerera kweropa.
