Mumamiriro ezvinhu akadaro, kupfuurira kunopfurikidza kwemvura imwe chete kunogona kuputirwa kuburikidza nechidzitiro zvakare uye zvakare.
Ropa rinopararira mumuviri wako kuburikidza ne arterial system- arterial , arterioles, uye capillaries - uye inodzokera kumwoyo wako kuburikidza nehutano hwemhepo-mitsipa nemavhutu. Ropa rako rinokosha pakurarama kwako uye rinoparadzira mishonga inosanganisira electrolytes, oksijeni, carbon dioxide uye amino acids mumuviri wako wose. Mwoyo wako ndiwo unokonzera huwandu hwehupenyu hwemhirizhonga yehurongwa uye ndiyo inotanga kuitwa.
Kurwisana Kunotanga Mwoyo Wako
Izvo-circulatory system inotanga muatorium yako yakarurama, kamuri yepamusoro-yekamuri yemoyo wako. Sezvo ropa richifamba kuburikidza nemoyo wako, rinopinda nepakati pemakamuri mana (kumusoro kwepamusoro, kuruboshwe, kuruboshwe kuruboshwe, kuruboshwe kuruboshwe), inotora nguva pfupi kumapapu kubvisa carbon dioxide uye kutora oksijeni, uye inoguma mumukati wezasi, kuruboshwe, inonzi "left ventricle".
Kana zvasvika pakupararira ropa mumuviri wako, kuruboshwe rwemhepo yakakosha ndiyo kamuri inokosha kupfuura dzose mumoyo.
Mhepo yakasara inotenderera ndiyo yakawanda pamakamuri mana uye ine basa rekudzikisa simba rinodiwa kubudisa ropa rako kubva paaorta yako, aritari yekutanga ropa rako rinopinda sezvainosiya mwoyo wako.
Kubva paAorta yako kuenda kune Capillaries yako
Ropa rako rinofamba kubva paaorta yako kuburikidza nemaketani emidziyo yeropa shoma kusvikira yasvika kumapilisa yako.
Usati wasvika kumapilisare ako, zvisinei, ropa rinofanira kufamba nerutivi rwe arterioles, uko kukurumidza kwayo uye zvinomanikidzwa zvinogara zvichishandurwa sezvikamu zvakasiyana zve arterioles kushandura hupamhi pakupindura kumanikidzi uye makemikari emagetsi akamira pedyo. Aya masvikiro anoshandura ropa achiyerera kuburikidza ne arterioles pakupindura kuchinja kwemuviri mumuviri wako.
Nokuda kwekuita kweArteriole, nenguva iyo ropa rako rinosvika pamakumbo ako, haasisiri kufamba mukufema.

Dzokera Kumwoyo Wako Uye Kwosezve
Sezvo ropa richifamba nemapapillari, iyo inopa oxygen yakaderedzwa uye yakatora zvidhazvo zvakare. Kubva pamapapillari, ropa rinopinda mavhesi, mitsetse, uye zvino rinodzokera kumwoyo kuti rizorodzwe uye rinotumirwazve zvakare.
