Basa mwoyo

Munhu wose anoziva kuti kukura mwoyo angaenzaniswa aine vakarumanisa nechibhakera. Asi kwete vose vanoziva kuti rimwe zuva rinogona pumped anenge gumi nezvitanhatu namazana matatu namakumi matanhatu litres ropa. Kurema ichi nhengo inokosha iri pakati maviri nemakumi maviri nemashanu kusvika matatu namakumi mana magiramu. On sei mwoyo inoshanda, izvozvo zvinoenderana zvinonyatsorehwa hutano hwehama. Maererano ayo mamiriro anogona kuenzaniswa mwoyo miviri-storey imba. Mumwe nomumwe wemigove ane yepamusoro uye yakaderera atrial manda nzvimbo, kurudyi ventricle.

basa mwoyo haagumiri kuti wechipiri. Uye kana iwe kuongorora zvakadzama kubatana vose dzakapoteredza zvikamu, unogona kungoti kuyemura chikwata mabasa avo. On mativi ose nzeve pakati ventricles uye pane musuo, yainzi vharuvhu. Ventricles uye arteries vari outputs uye zvinoshandisa pakurima zviri kubva mutsinga kusvika lugs. A mwoyo hwakanaka zvakakwana mikova akanyatsokodzerwa, sezvo mumwoyo misha ropa kumukova chete hapafanire kuva. Kuvhara uye kuvhura vharuvhu kunouya mumwe mutinhimira urove komoyo wangu.

On mativi ose mumwoyo kwazvo ane pombi. Kurutivi chiedza rworuboshwe rinobuda ropa vafumiswa pamwe oxygen, uye achaendeswa pamusoro muviri. Ropa anopinda kurudyi ane okisijeni maduku, asi ine zvakawanda rine carbon dioxide, uye anodzoka nayo mumapapu.

The auricles akaumbwa masvingo wakawondereiko kudai mazuva ose, sezvo ivo kupomba ropa kupinda kure duku. Right ventricular rusvingo ukobvu, nokuti anotumira ropa mumapapu. Asi chinonyanya kukosha mwoyo kuti ventricle kuruboshwe, uye ine chaizvo gobvu masvingo, nekuti daro kuti anofanira kupomba ropa, ndicho chikamu chikuru.

Haasi munhu wose anogona kufungidzira kuti zvakakomba basa mwoyo, compression uye decompression riri anenge zana chiuru nguva masikati.

The simba iro moyo ipfupi, hakusi chete nguva dzose. Munguva mumuviri basa chiri kuwedzera kwebasa arteries duku uye capillaries ari kushanda tsandanyama uye ropa riyerere kwavari anowedzera. Tsandanyama mukuderedza dzvinya tsinga uye akasunda akananga yakawanda ropa mwoyo. Simba marwadzo tsandanyama, kusanganisira mwoyo, zvinoenderana kwokutanga Stretch. kureva, kana vari kumwezve, ivo elongated fibers, uye ipapo tsonyera vachava kusimba. Mwoyo kuti anogamuchira mari vakawedzera ropa kuchawedzera uye nokudaro tsandanyama fibers elongate. The rutapudzo mwoyo kuenda simba. Wana zvimwe ropa, zviri muna vakawanda anomhanyira mariri kupinda arteries. Nokudaro ropa kuparadzirwa rwuchiwanzwa, uye vose zvomukati panguva imwe chete mamwe zvinovaka muviri uye ukuwo okisijeni.

Kana munhu utano, basa mwoyo rinoitwa rhythmically pasina anokonzera chero matambudziko. Zvisinei, mwoyo wake tsandanyama anorwara kana simba, kushanda nesimba uye Anoshanduka yakawanda ropa yakawedzera kurovedza muviri, iye haagoni. Also chibharo uye basa simba mwoyo. Kana usingagoni yakakwana nhamba kugovera ropa riyerere kuti nhengo, ipapo munhu mamiriro inonzi mwoyo kukundikana.

In vanhu vane mwoyo chirwere kwemwoyo panguva yechiitwa yekudyidzana unoraramisa uye pachinzvimbo anorova makumi masere paminiti wasvika rimwe namakumi mana lashes. Mwoyo kutadza kunonyanya rinokanganisa uropi. Kana munhu kufema muzinda akaita ropa kuyerera diki uye kushomeka okisijeni uye carbon dioxide panguva imwe chete iri kwakaratidzwa pagungano zvishoma kumhanya, ipapo kutsamwa ari kufema zvomukati. Panyaya iyi, murwere anonzwa pfupi kufema.

The chirwere Nhengo ichi chinokosha kunowanzoguma zvisingafadzi nezvekufadza, tingling mumwoyo. Uyewo tachycardia kuchengetwa inorema mumakungwa, mumwe neurosis.

Kunyange kana basa harisi zvakakomba mwoyo yevanhu utano, hazvirevi kuti rirege kudzivirirwa. Naizvozvo, mutoro pamusoro zviri zvinodiwa kuderedza kushoma, nokuti basa mwoyo kunotemwa nokureba kwoupenyu hwevanhu.
