Chii mwoyo hove? hove Makamuri mwoyo

Chokwadi, hove uye vamwe hwemvura vagari vane mwoyo, iro rine zvakafanana zvatariswa kumunhu, achiita paro kushanda ropa nerubatsiro muviri. Mune chete pamakumbo imwe uye akapfiga akasiyana evanhu makopi wemuTesitamende hove. Munhuwo bezhryaschevyh hove ropa riyerere kunoitika muna yakarurama mitsetse, uye yakakwirira shwashwa - pezvakaita Chirungu tsamba S. musiyano uyu nokuda kunzwisisa maumbirwo nhengo dzose kweropa ino uye dzakasiyana Zvinoumba Ropa. Pakutanga ino, isu funga mwoyo zvavo hove, uye ipapo ita shwashwa kunoshamisa vagari mvura nyika.

muviri kunokosha

Mwoyo - ndiyo huru uye chikuru chomunhu upi pakati kweropa hurongwa. In hove, uyewo vanhu uye dzimwe mhuka vane mwoyo. It zvingaita sezvinoshamisa, nekuti hove mhuka ine utsinye, mukusiyana kwatiri. muviri uyu tsandanyama zai, riri kuramba huchidzikira, nokudaro kupomba ropa rose muviri.

Chii mwoyo hove uye kufamba kweropa rikauya, unogona kudzidza nokuverenga mashoko ari munyaya ino.

Saizi muviri

The kukura mwoyo kunobva zvachose muviri uremu, saka yakakura hove, zvikuru ayo "motokari". mwoyo yedu rinofananidzwa chakakura chibhakera, hove asingagoni. Asi sezvo tichiziva kubva zvipenyu zvidzidzo panguva mwoyo nehove duku chakakura masendimita mashomanana. Uye pano panguva huru vamiririri muviri nyika pemvura vanogona kusvika kunyange maviri kana matatu masendimita. hove idzi zvinosanganisira Catfish, Pike, kabhu, Sturgeon, uye vamwe.

Uripiko mwoyo?

Kana munhu nehanya mubvunzo kuti zvikuru mwoyo hove, pakarepo vanopindura - mumwe. Zvinoshamisa kuti nyaya iyi inogona kazhinji kuva, asi sezvo tsika inoratidza, kungadaro. Kakawanda kana rokuchenesa vemba hove havazivi kunyange kuti vanogona kuwana nyore mwoyo. Somunhu, mwoyo hove iri Anterior mudunhu muviri. Kana kuva munoreva, chete pasi gills. On mativi ose mwoyo runochengetedzwa mbabvu, uyewo needu. The nhamba, izvo unogona kuona pazasi, chikuru muviri hove akanzi nhamba imwe.

mamiriro

Akapiwa hunhu afemeruke ehove uye kuti vane gills, mwoyo eMweya yakasiyana kupfuura mhuka yenyika. Nemaziso, mwoyo hove iri muchimiro akafanana needu. Little dzvuku bhegi duku rakachenuruka vaaleanpunainen bhegi nechepasi uye kune muviri ichi.

Mwoyo upenyu hwemvura ine utsinye ane mbiri chete makamuri. Kureva ventricle uye atrium. Ivo riri pedyo napedyo kuti, kana kuti kuva kunyatsoenderana, mumwe pamusoro pomumwe. Ventricle ari atrium uye ine raita mumvuri. Hove vane mwoyo rinoumbwa tsandanyama rinenge imhaka yokuti anozadzika basa rimwe pombi uye akaramba kuderedzwa.

kutenderera vanoronga

mwoyo hove zvakabatana pakati gills tichibatsirwa pakati arteries, izvo riri nedivi huru abdominal tsinga. It inonziwo abdominal yeropa, mukuwedzera, pamwe yose muviri atrial vatungamirire matete mutsinga kuti ropa inoyerera.

Blood hove akapfuma carbon dioxide, izvo zvinofanira kupatsanurwa sezvinotevera. Achipfuura ari mutsinga, ropa zvikanzwika moyo hove, apo pamwe kubatsira atria iri pumped kuburikidza arteries ari gills. Gills, akavapindurawo, akapa vane muzvizhinji kuti capillaries yakanaka. capillaries ava zvose gills uye achakubatsira akakurumidza zvifambiswe kupomba ropa. Zvadaro, zviri gills ose carbon dioxide inobvisa hwakakanyiwa uye kushandurwa kuti okisijeni. Ndokusaka zvichikosha kuti kuchengeta mvura apo hove kurarama, akanga nomuti oxygen.

Okisijeni ropa mberi rwendo rayo kuburikidza nomuviri hove uye akatumira huru yeropa, riri pamusoro muhomba. Kubva tsinga ichi bazi kubva muzvizhinji kuti capillaries. In ropa ravo kuparadzirwa kunotanga, asi, kuchinjanisa, nekuti sezvo tinoziva, kubva gills oxygenated musana ropa.

Zvinoguma yokutsiva ropa mumuviri rehove. The ropa kubva arteries, izvo kazhinji anotarira mupfumi dzvuku, kuchinja kuti ropa kubva tsinga, inova zvasviba zvikuru.

Nhungamiro wokufambisa

Heart makamuri hove dziri atrium uye ventricle, ayo takashongedzerwa chaizvo mavharuvhu. Nokuda mavharuvhu izvi kufamba ropa kunoitika mune mirayiridzo imwe chete, kubvisa neizvi kuraswa. Izvi zvinokosha zvikuru nokuti vapenyu muviri.

Vienna akatuma ropa iri atrium, uye kubva ipapo inoyerera kukamuri wechipiri mwoyo rehove, uye zvadaro chaizvo zvomukati - gills. Zvapedzisira inofamba kunoitika kuburikidza chikuru abdominal yeropa. Saka, tinogona kuona kuti mwoyo hove anoita yakawanda kusingaperi acronyms.

Heart cartilaginous nehove

Ichi kunyanya kirasi hove, iyo inozivikanwa nokuva pamberi dehenya, musana uye sandara gills. The yakakurumbira mumiririri mukirasi iyi inogona kunzi Sharks uye mwaranzi.

Kufanana nehama dzavo bezhryaschevyh mwoyo cartilaginous hove rine mbiri makamera uye mumwe kufamba kweropa. Muitiro kupanana carbon dioxide inobvisa kuti okisijeni kunoitika nenzira sokurondedzerwa apa, mashomanana zvinhu. Izvi zvinosanganisira kuvapo spiracle, izvo zvinobatsira kuti mvura kusvika gills. Uye zvose nokuti gills hove dziri munzvimbo abdominal munharaunda.

Chimwe nevamwe chinhu ndiyo kuvapo muviri yakadai chirwatata. Iyewo, ndeyekupedzisira vanorega ropa. Izvi zvakakodzera kuitira kuti panguva imwe basa chakaitika wokupedzisira nokukurumidza chikafu kuruoko muviri.

Blood hove cartilaginous yakareba nomuti okisijeni, nokuda vakawanda masero matsvuku eropa. Uye zvose nokuda vawedzere basa itsvo, apo ndiko kukura kwavo.
