Tsinga vs. tsinga

Arteri ndiwo mitsipa yeropa inoitisa kutakura oxygen-yakazara ropa kubva pamwoyo kuenda kumuviri. Tsinga imidziyo yeropa inotakura ropa rakadzika muoksijeni kubva mumuviri ichidzokera kumoyo kuitira reoxygenation.

Tsinga uye tsinga ndiwo maviri erudzi rukuru rwemuviri wetsinga dzeropa. Iyi midziyo migero inoendesa ropa kumuviri. Ivo chikamu chemaviri akavharwa masisitimu emachubhu anotanga nekuguma pamoyo. Aya masisitimu emachubhu angave:

• Mapapu. Midziyo yemapurmari ndiyo tsinga dzinotakura okisijeni-isina ropa ropa kubva pamwoyo kurudyi ventricle kuenda kumapapu. Mapuroni tsinga anotakura okisijeni-yakapfuma ropa kudzokera kumoyo kuruboshwe atrium.
• Systemic. Midziyo yesystem ndiyo tsinga dzinotakura okisijeni-yakazara ropa kubva pamwoyo kuruboshwe ventricle kuenda kumatishu mumativi ese emuviri. Ivo vanobva vadzorera oxygen-muropa reropa kuburikidza netsinga dzokera kumoyo atrium chaiyo.

Ndeapi marudzi akasiyana etsinga?

Kune mhando nhatu dzetsinga. Mhando yega yega inoumbwa nemajasi matatu: ekunze, epakati, uye emukati.

• Tsinga dzakavharwa inonzi zvakare kuitisa tsinga kana kondiriti tsinga. Ivo vane gobvu repakati repakati kuti vagone kutambanudza mukupindura kune yega yega kurova kwemoyo.
• Tsandanyama (kugovera) tsinga zviri pakati nepakati. Vanokwevera ropa kubva kune yakasununguka arteri uye bazi mumidziyo yekudzivirira. Iyi midziyo inosanganisira tsinga diki uye arterioles.
• Arterioles ndiwo chikamu chidiki chetsinga dzinoendesa ropa kure nemoyo. Ivo vanonongedza ropa mukati ma capillary network.

Ndeapi marudzi akasiyana etsinga?

Kune marudzi mana etsinga:

• Tsinga dzakadzika inowanikwa mukati memhasuru nyama. Ivo vane arteri inoenderana padyo.
• Tsinga dzepamusoro vari padyo nechepamusoro peganda. Havana tsinga dzinoenderana.
• Tsinga dzemapapu kutakura ropa rakazadzwa neoksijeni nemapapu kuenda pamoyo. Mapapu ega ega ane seti mbiri yemapapu emapapu, kurudyi uye kuruboshwe.
• Tsinga dzakarongeka inowanikwa mumuviri wese kubva pamakumbo kusvika pamutsipa, kusanganisira maoko ne trunk. Ivo vanotakura deoxygenated ropa kudzokera kumoyo.

Artery uye vein dhayagiramu

Shandisa iyi inofambidzana 3-D dhayagiramu yekuongorora arteri.

Shandisa iyi inofambidzana 3-D dhayagiramu yekuongorora mutsinga.

Anatomy yetsinga uye arteri

Iwo madziro etsinga uye arteri ese ari maviri akaumbwa nematatu matatu:

• Kunze. Tunica adventitia (tunica externa) ndiyo yekunze chikamu chemidziyo yeropa, inosanganisira tsinga uye tsinga. Inonyanya kuumbwa ne collagen uye elastic fiber. Tambo idzi dzinogonesa tsinga netsinga kutambanudza hushoma. Ivo vanotambanudza zvakakwana kuti vagone kuchinjika vachichengetedza kudzikama pasi pekumanikidza kweropa kuyerera.
• Pakati. Pakati pepakati pemadziro etsinga uye tsinga inonzi iyo tunica media. Yakagadzirwa nemhasuru dzakatsetseka uye elastic fiber. Rukoko urwu rwakakora mutsinga uye kuonda mutsinga.
• Mukati. Icho chemukati chemadziro eropa remidzi chinonzi tunica intima. Rukoko ichi chakagadzirwa kwakavharwa nenyama faibha uye collagen. Kuenderana kwaro kunosiyana zvichienderana nerudzi rweropa.

Kusiyana netsinga, tsinga dzine mavharuvhu. Tsinga dzinoda mavharuvhu kuitira kuti ropa riyerere richienda kumoyo. Iwo mavharuvhu anonyanya kukosha mumakumbo nemaoko. Ivo vanorwisa giravhiti kudzivirira kubuda kweropa shure.

Tsinga hadzidi mavhavha nekuti kumanikidza kunobva pamoyo kunochengeta ropa richiyerera nepakati munzira.

Iyo yemoyo system

Iyo yemoyo system ndiyo yakavharwa system yemidziyo inonzi arteri, tsinga, uye capillaries. Dzese dzakabatana nepasuru pombi inonzi moyo. Iyo yemoyo maseru system inochengeta inoramba ichienderera uye inodzorwa kufamba kweropa iro rinoendesa zvinovaka muviri uye oxygen kune ese sero mumuviri. Inoita izvi kuburikidza nezviuru zvemamaira ema capillari pakati petsinga netsinga.

• Tsinga. Iyo pulmonary arteri inotakura yakaderera-oxygen ropa kubva kurudyi ventricle yemoyo kuenda kumapapu. Masystemic arteri anotakura oxygenated ropa kubva kuruboshwe ventricle yemoyo kuenda kune yakasara yemuviri.
• Tsinga. Tsinga dzemapapu dzinotakura oxygenated ropa kubva mumapapu kuenda kuruboshwe atrium yemoyo. Masystemic tsinga anotakura yakaderera-okisijeni ropa kubva mumuviri kuenda kurudyi atrium yemoyo.
• Capillaries. MaCapillaries ndiwo madiki uye akawanda kwazvo emidziyo yeropa. Zvinobatana pakati petsinga (dzinotakura ropa kubva pamoyo) uye tsinga (idzo dzinodzosera ropa kumoyo). Basa rekutanga re capillaries iko kuchinjana kwezvinhu, senge okisijeni, pakati peropa uye maseru maseru.
• Mwoyo. Moyo une makamuri mana: kurudyi atrium, kurudyi ventricle, kuruboshwe atrium, uye kuruboshwe ventricle. Moyo unopa simba kutenderera ropa kuburikidza nemoyo wemasisitimu.

Kutora

Nutrients uye okisijeni zvinounzwa kumasero ese ari mumuviri wako kuburikidza necirculatory system. Moyo unopomba ropa rine oxygenated kumasero ako kuburikidza netsinga. Inopomba oxygen-yakazadza ropa kure nemaseru ako kuburikidza netsinga.
