Human kumwoyo - chimwe chezvinhu zvinokosha mugadziriro nhengo, riri basa kuita mabasa akadai zvekufambisa nezvinovaka muviri, mahormone, magasi, uye metabolic zvigadzirwa kubva masero uye pacho, kudzivirirwa masero vatorwa uye anokuvadza tupukanana tusingaoneki, mutemo tembiricha muviri. mabasa ose aya anoitwa pasi node uye ropa zvakananga. Ropa imvura connective zvinyama, achiparadzira munyika midziyo ropa uye node - mvura, akajeka mvura ine chena ropa masero uye riri lymphatics.

Chezvakanaka kumwoyo?

The chikuru zvinoumba kumwoyo vari midziyo ropa (mutsinga, arteries uye capillaries) kuti pinda nhengo dzose uye hurongwa, uye mwoyo, ndiye hurongwa chinokosha muviri. Basa sei "utano" kana "kwete utano" midziyo yenyu ropa kunoenderana nebasa rose muviri. Heart Weight avhareji iri magiramu 300, uye kukura - ari Clenching chibhakera. The mwoyo anokwanisa kubvisa 5 litres ropa paminiti pa zororo uye 25-35 litres / min. kukwanisa maekisesaizi.

The chikuru basa mwoyo ndiwo mutinhimira kufamba kweropa kuburikidza nhumbi; inoitwa ventricles maviri kuita pombi nerevane maviri atria, umo ropa inounganidzwa.
