Yintoni intliziyo ntlanzi? amagumbi iintlanzi intliziyo

Kakade ke, intlanzi kunye nezinye abemi zasemanzini kwabantliziyo, leyo uneempawu ezifana zabantu, ekwenzeni umsebenzi walo ongundoqo unikezelo igazi emzimbeni. Ithanga nje omnye yaye Eyisongile azifani yabantu inkqubo kwegazi iintlanzi. EziQhelekileyo bezhryaschevyh fish flow kwegazi kuyenzeka imigca ethe ngqo, kwaye intlala ephakamileyo - imilo le leta IsiNgesi S. Lo mahluko kungenxa isakhiwo oluntsonkothileyo amalungu kwegazi kunye ezahlukeneyo nokwakheka egazini. Ekuqaleni kweli nqaku, sicinga intliziyo iintlanzi eziqhelekileyo, uze ugqithele intlala abemi ezimangalisayo zehlabathi anzongonzongo.

umzimba ebaluleke

Intliziyo - yengundoqo kunye umzimba omkhulu nayiphi na inkqubo yokujikeleza. Iintlanzi, kwakunye ebantwini kunye nezinye izilwanyana abe nentliziyo. Oku kubonakala engaqhelekanga, ngokuba wentlanzi izilwanyana zinegazi elibandayo, ngokuchaseneyo kuthi. Le yinto nje sac dystrophy, nto leyo rhoqo ukuhla, ngaloo ndlela zokumpompa igazi wonke umzimba.

Yintoni na ke intliziyo intlanzi kunye nentshukumo kwegazi kwenzeka, unako ukufunda ngokufunda ulwazi kweli nqaku.

nomzimba

Imilinganiselo intliziyo kuxhomekeke ubunzima emzimbeni wonke, ngoko ke ezinkulu iintlanzi, kokukhona "motor" yayo. intliziyo yethu kuthelekiswa nobungakanani ngenqindi, intlanzi akakwazi. Kodwa siyayazi ukusukela kwizifundo biology intliziyo intlanzi encinci isayizi besentimitha ezimbalwa. Kwaye apha abameli ezinkulu umzimba yehlabathi kwamanzi nga kufikelela amabini okanye amathathu cm. Le ntlanzi ziquka catfish, Pike, zeCARP, Intlanzi, kunye nabanye.

Uphi na intliziyo?

Ukuba umntu ochaphazelekayo kunye umbuzo kangakanani iintliziyo intlanzi, ngoko nangoko phendula - nye. Kuyamangalisa ukuba lo mba unokuba ngokubanzi, kodwa ke njengokuba kusenziwa sibonisa, ungakwazi. Amaxesha amaninzi xa uhlamba engaphangeliyo iintlanzi ngisho nokuwabona ukuba lula ukufumana intliziyo. Njengoko umntu, intliziyo intlanzi ekummandla Icipande umzimba. Ukuba ukuba ngakumbi ngqo, ngaphantsi nje iigilizi. Kumacala omabini intliziyo mazikhuselwe iimbambo, kwakunye neyomntu. Lo mzobo, apho ubona ngezantsi, umzimba omkhulu iintlanzi enombhalo Inani enye.

isakhiwo

Xa sijonga iimpawu nokuphefumla yeentlanzi nokuba babe iigilizi, ndoba intliziyo eyahlukileyo izilwanyana ezisentlabathini. Ezibonakalayo, embilinini wentlanzi ngendlela efana neyethu. bag Little ebomvu kunye baluthuthu epinki ibhegi esezantsi amancinci kwaye kukho lo mzimba.

Heart zinegazi elibandayo ubomi emanzini iye amagumbi amabini kuphela. Ezizezi ventricle kunye intendelezo. Bona zibekwe kufutshane, okanye ukuba ngqo ngakumbi, enye phezu kwenye. Ventricle na intendelezo features a umthunzi lighter. Iintlanzi ndinentliziyo eyenziwe esiqwini izihlunu, kungenxa yokuba oko ezalisekisa indima impompo kunye ngokuqhubekayo lincitshiswe.

scheme kwegazi

Intliziyo intlanzi liqhagamshelene iigilizi ngoncedo kwemithambo, apho ibekwe ngapha nangapha kwemithambo engundoqo esiswini. Kwakhona ngokuba aorta esiswini, ukongeza, kunye umzimba lonke imithambo atrial phambili ubhityile ukuba igazi eliqukuqela.

Blood fish osisityebi ikharbon dayokhsayidi oyikhupha ngonyaka, ekufuneka kwenziwa ngolu hlobo lulandelayo. Ehambahamba imithambo, igazi ufumana entliziyweni wentlanzi, apho ngoncedo imithambo Impontshelwa ngokusebenzisa imithambo iigilizi. Iigilizi, ke, banikwa nobuninzi ngcanjana emihle. Ezi emithanjeni yonke iigilizi kwaye aya kukunceda ngokukhawuleza ithuthwa okumpompa igazi. Emva koko, oku Kwakukhuhlwa yekharboni dayokhsayidi oxutywe kwaye itshintshwe ukuze oksijini. Yiyo loo nto kubalulekile ukugcina amanzi bahlala apho intlanzi, waye befumile mpilo.

igazi Oxygen iyaqhubeka uhambo lwayo ngawo umzimba iintlanzi wathumela aorta engundoqo, leyo phezu ephakeme. Ukususela kule kwemithambo isetyana ezininzi emithanjeni. Ejikelezayo igazi labo luqala, kunoko, utshintshiselwano, kuba siyazi ukuba, ukususela iigilizi umva igazi nomoya.

Isiphumo indawo igazi emzimbeni sentlanzi. Igazi evela imithambo, leyo ngokuqhelekileyo ikhangeleka obomvu, utshintsho igazi apho iphuma khona, nto leyo mnyama kakhulu.

Indlela ejikeleza

Heart amagumbi zeentlanzi intendelezo kunye ventricle, ezo baxhotyiswa kwezivalo ezikhethekileyo. Ngenxa kule mbobo ukuhamba kwegazi kwenzeka kwicala elinye kuphela, ukuphelisa ukulahlwa umva. Oku kubaluleke kakhulu kuba esiphilayo.

Vienna wathumela igazi intendelezo, yaye ukusuka apho amdaka ukuya egumbini yesibini kwentliziyo intlanzi, nakuzo amalungu athile - iigilizi. Isindululo yokugqibela kwenzeka xa ophambili aorta esiswini. Ngenxa yoko, siyabona ukuba intliziyo ntlanzi kwenza ezininzi akhronimi obungenasiphelo.

Heart neentlanzi cartilaginous

Oku ethile udidi intlanzi, esibonakala bubukho lukakayi, umqolo kunye iigilizi flat. Ummeli idumileyo yale iklasi ingabizwa sharks ray.

Kanye izihlobo zabo bezhryaschevyh iintlanzi intliziyo cartilaginous iye iikhamera ezimbini enye ejikelezayo. Inkqubo yokutshintshiselana carbon dioxide oksijini lwenzeka ngendlela efanayo njengoko kuchaziwe apha ngasentla, iimpawu nje ezimbalwa. Ezi ziquka phambi spiracle, nto leyo inceda ukufumana amanzi ukuya iigilizi. Kwaye ngenxa Kwakukhuhlwa iintlanzi ibekwe kwindawo esiswini.

Enye into lisahlulayo phambi umzimba efana udakada. Yena, ke, nguye stop lokugqibela egazini. Oku kuyimfuneko ukuqinisekisa ukuba kwixesha umsebenzi ethile yenzekile ifidi yokugqibela ngokukhawuleza kwi umzimba ekunene.

Blood fish cartilaginous elide okroqiweyo ioksijini, ngenxa yenani elikhulu iiseli ezibomvu zegazi. Kwaye bonke ngenxa umsebenzi eyandisiweyo nezintso, apho uphuhliso lwabo.
