Enhliziyweni yomuntu nokwakheka

Anatomy futhi physiology inhliziyo ahehe njalo abacwaningi. Lokhu kuyaqondakala, ngoba inhliziyo - kuba umzimba kuphela usebenza autonomously. Kusukela umsebenzi wakhe kuncike isimo jikelele zomzimba, ezempilo kanye nokugula. Empeleni, ne beat lokuqala umzimba, ukuphila komuntu okuqala ngaso ne kick zokugcina eyeka.

enhliziyweni yomuntu anatomy kuyinto ngempela eziyinkimbinkimbi - umzimba wenza umsebenzi omkhulu, ukuhlinzeka wonke umzimba ngegazi. Ngaphandle, inhliziyo ine uhlobo Isigaxa, ngaphakathi nomgodi uphahlwe ungqimba musculo-fibrous. Umgomo we operation wenhliziyo kunqunywa oyiyo. It sifana futha ezimbili isigaba: esigabeni sokuqala kuyinto ventricle, epompa igazi phakathi ATRIUM, kanti eyesibili esiteji - ATRIUM iphampa igazi ku le-aorta. Kungenzeka ukumpompa igazi lutholakala ngokusebenzisa septum atrioventricular - ukuthi lusebenza futhi piston, futhi valve.

Anatomy of the inhliziyo, naphezu kwezinkinga elalibhekene Libhukutifundvo lelimiselwe canons ngokuphelele ngabanye. Ngisho njengoba injalo, kungase ziyahlukahluka kuye izinto eziningi. inhliziyo Kutholwe futhi akufani - Kubantu abaningi ishiywe nge-offset sikhungo, futhi kwezinye it is elivulela maphakathi, ngisho ne shift ilungelo. inhliziyo engalingani kanye nemingcele imethrikhi - ke ngokuvamile enwetshiwe phezulu futhi ayisesemikhulu ezansi, kodwa isilinganiso lezi zinombolo ngazo zonke ezihlukahlukene (ikakhulukazi lincike ohlotsheni yomthethosisekelo). Inhliziyo mass emabangeni isilinganiso kusukela amabili namashumi amahlanu kuya amagremu amathathu namashumi amathathu.

Anatomy of the inhliziyo, njengoba isitho eyinkimbinkimbi kunazo ngokwanele wafunda kuze kube manje. Inhliziyo has a isikhwama senhliziyo ebizwa ngokuthi pericardium. Siqukethe yena, izingqimba ezintathu ukujiya ezahlukene, ezahlukene ngokucacile yabo futhi imisebenzi ehlukene. Ngokusho isakhiwo inhliziyo sehlukaniswe emakamelweni ezine - uMnyango. It kwesokunxele futhi ventricles kwesokudla, kwesokunxele Atria kwesokudla. Phakathi kwalezi zinhlangothi kwesokunxele nakwesokudla ukwahlukanisa yezinto. Esikhathini ATRIUM kwesokudla agelezela Vienna eziyize, futhi kuya ATRIUM kwesokunxele kuvumelana Umthambo yamaphaphu. Kusukela i-ventricle engakwesobunxele phandle le-aorta ngesifuba, bese kusuka kwesokudla - umfula yamaphaphu.

inhliziyo anatomy kuyinto ethize iqiniso lokuthi ventricles akuzona umfaniswano ukujiya yabo. Ngokwesibonelo, i-ventricle engakwesobunxele kuyinto izindonga mkhulu (kathathu mkhulu kunokhalo izindonga ngakwesokudla), kusukela ventricle engakwesobunxele ipompela igazi ukuze kwegazi, ngawo elulele wonke umzimba. Ngenxa yalokho, kumbuthano ezinkulu futhi wegazi ngaphezulu.

Ukuze inhliziyo alaneliswa ngegazi efanayo ziphonswe inhliziyo has valve. Esikhathini esithile valve ivaliwe isikhala ukugeleza kwegazi, noma uyivule. Ngakho, kukhona ukugeleza kwegazi ohlangothini oyifunayo.

Uma anatomy wenhliziyo akuyona burdened nga ngalindelekile imihlola sokugembula, umsebenzi komqondo inhliziyo. umsebenzi senhliziyo ingahlukaniswa ngemijikelezo - omunye umjikelezo unezigaba ezintathu. Isinyathelo sokuqala siwukuba nokwehlisa atriums ezigcwele igazi. Ngokusebenzisa ama-valve evulekile igazi engena ventricles, nakho kuyehla, kanti noHezekeli ATRIUM - uphumule. Ngalesi sikhathi, umsebenzi wakhe kwenza valve ukuvala sokuhoxisa igazi. Esigabeni esilandelayo - kokuhlaba ikhefu, igazi ageleza kalula, lapho inhliziyo uhlezi. Lokhu kwenzeka ngempela eside - isekhondi okuhlukene.

Anatomy of the inhliziyo, futhi umsebenzi wakhe - buyinto eyinkimbinkimbi kakhulu kangaka. Ngemva innervation of imisipha yenhliziyo kwenzeka ngenxa ezahlukahlukene ezifana ubuhlobo izinhlelo sezinzwa futhi endocrine, khona imali eyanele potassium ion ne-calcium. Ukuze ukufunda umsebenzi inhliziyo futhi silungise izinkinga umsebenzi inhliziyo, wenze electrocardiogram. Ngosizo yalolu cwaningo, ingxenye enkulu usungula sitholakele pathologies inhliziyo.
