Kweropa maitiro

The kweropa Hurongwa iri rakaoma namahwindo richikurukura zvinosanganisira madenderedzwa maviri (arterial kana venous uye zviduku) kweropa uye "pombi nechepakati" - mwoyo.

midziyo All vanokamurwa kuva tsinga, ruduku ropa midziyo (capillaries), uye arteries. Mishumo Recent kushanda sechinhu okisijeni-vafumiswa, "zvakachena" ropa mapazi uye munyama. Arteries mune midziyo kupfuura dzakawanda kuti pane yakatanga tsandanyama jasi. Arterial ropa hurongwa rinosanganisira midziyo makuru, kuparara madiki (arterioles), izvo zvinozoita kuumba youpfu capillaries Network. Vakatakura matongo Absorção de Água uye voga anoshanda zvinhu uye oxygen. Kuburikidza rirambe richibvira arterioles remubatanidzwa yaakaita mutsinga munyama.

Venous kweropa kwava kukonzera kugadzirwa water drainage zvakazara ne carbon dioxide inobvisa ropa. Nokuti midziyo iyi ropa anodzokera mwoyo. Svikiro uye zviduku mutsinga vane mavharuvhu kudzivirira kudzoka (neizvi kufamba) ropa.

Mwoyo rinoratidza negomba tsandanyama nhengo pamwe makamuri mana. Zvinosanganisira atria maviri (kugamuchira yomukati) uye mbiri ventricles, kushanda sechinhu pombi. The mwoyo kugova hunyambiri partition. Kuruboshwe ventricle uye akasiya atrium delimited shavishavi mavharuvhu, rworudyi ventricle nezvakarurama atrium - tricuspid vharafu. By vharuvhu mapepa vari vasiyana ventricular kurutivi mutsvuku nemarunda. Basa vharuvhu - kudzivisa neizvi kufamba kweropa.

It runopoteredza mwoyo yakasimba coupling pahombodo - the pericardium.

Sezvataurwa pamusoro apa, kweropa hurongwa unotora maviri kweropa hurongwa. Zvisinei, kazhinji, nyanzvi dzinoti, uye wechitatu - moyo denderedzwa. Zvinonzi nevamwe nokuda kukosha kwayo, sezvo zviri kukonzera kurwiswa. Tanga denderedzwa nhema zviviri coronary (coronary) arteries, tsvina kubva mujinga vachikwira yeropa. Kupinda mwoyo myocardium, zvinoumba richikurukura arteries duku. The myocardium kunoratidzwa munhu zvakanaka zvakanaka dzakabudirira samambure capillaries, ichipa kuchinjaniswa pezvakaitwa ari tsandanyama tishu. Of myocardial venous ropa runoyerera mukati rworudyi chikamu mwoyo kuburikidza coronary mutsinga dzakawanda. Nengano rutapudzo mwoyo tsandanyama neBP akasikwa. Nokuda ndiwo kwebasa arterial ropa.

denderedzwa Large inotangira ventricle kuruboshwe. Marwadzo mwoyo tsandanyama sangano kunoita arterial ropa kurutivi yeropa, uye ipapo ose nhengo uye munyama. Saka pane kudzoka muviri zvinhu uye okisijeni saturation ropa muchitokisi basa uye zvigadzirwa pamwe carbon dioxide. The muunganidzwa ropa rikaitika mutsinga kuburikidza capillaries. Mushure okumusoro nayo anopinda tsinga kupinda zvakanaka atrium, nokuvhara guru denderedzwa.

Small Circle dzakatangira zvakarurama ventricle. Ropa kubva mutsinga vakapinda rworudyi atrium, runoyerera munzvimbo zvakanaka ventricle, iro chiedza anopinda tsinga. Achipfuura pulmonary capillaries, zviri asunungurwa carbon dioxide inobvisa uye oxygenated anova arterial uye runoyerera kupinda atrium kuruboshwe.

Phylogeny of kweropa kwava zvakakura vertebrates zvose. Sechivako ino zvinosanganisira yeropa, asi microcirculatory mubhedha (kusanganisira rirambe richibvira pomumbure), arteries, mutsinga uye mwoyo. Mukuita yemhindumupindu yaiitwa kuparadzana ari nhengo dzinobudisa network. Kuchinja kukuru mune sechivako kweropa ino zvinosanganisira kuchinja kubva dakashwa mhando kufema kwacho kune pulmonary nzira.

Kweropa hurongwa chirwere (vascular chirwere) rinowanzoshandurwa kurapwa maererano mhando ane nhumbi. Somuenzaniso, achitambanudza mu vascular masvingo kumutsa aneurysm. Yeropa kazhinji kuva atherosclerotic kana zvirwere kwendangariro. atsamwira Its anogona kuitika nokuda yokusafa neutera masvingo kana zvinokuvadza. The pulmonary arteries anogona kuitika arteriosclerotic kuchinja kuitika kana vachiberekwa abnormalities. Zvinoreva arterial kazhinji zvinokanganisa atherosclerosis. The mutsinga Kazhinji varicose kana zvomoto (phlebitis).
