# Isingeniso Somkhiqizo Wemodeli Yenhliziyo Enezingxenye Ezintathu Ezi-5x
I. Ukubuka Konke Komkhiqizo
Imodeli yenhliziyo enezingxenye ezintathu ezi-5 iyinsiza yokufundisa yobungcweti eyenzelwe ngokukhethekile ukufundisa kwezokwelapha, imibukiso yesayensi ethandwayo kanye nosizo locwaningo oluhlobene. Isakhiwo senhliziyo yomuntu silinganiswe kahle futhi sethulwa. Siyahlukaniswa futhi saklanywa saba izingxenye ezintathu eziyinhloko ukusiza abasebenzisi ukuthi bahlole ngokujulile isakhiwo somzimba kanye nobudlelwano bokusebenza kwenhliziyo.
Iinzuzo Eziyinhloko
(1) Ukulungiswa okunembile okunemininingwane ecacile
Ngokusekelwe ngokuqinile kudatha yokwakheka kwenhliziyo yomuntu, ngesilinganiso sokukhulisa esingu-5x, izakhiwo ezincane ezifana nomgodi wenhliziyo, ama-valve, nemithambo yegazi zihlukaniswa ngokucacile. Izikhombisi-ndlela zokuxhuma zemithambo yenhliziyo kanye nomehluko wokwakheka kwe-atria nama-ventricle konke kwethulwe ngokunembile, okunikeza izinkomba zangempela zokufundisa nokucwaninga.
(2) Umklamo ohlukanisiwe kanye nokufundisa okuguquguqukayo
Imodi yokuhlukaniswa kwezingxenye ezintathu eyingqayizivele ingabonisa ngokwehlukana isakhiwo sezindawo ezahlukene zenhliziyo. Kulula ngothisha ukuchaza isinyathelo ngesinyathelo, kusukela ekubukekeni okuphelele kuya ekusebenzeni kwamakamelo angaphakathi nama-valve, kanye nokuhlukaniswa nokuhlanganiswa, okusiza abafundi ukuthi basheshe basungule ukuqonda kwendawo futhi baqonde izindlela zomzimba ezifana nenhliziyo epompa igazi.
(3) Izinto ezihlala isikhathi eside zokusetshenziswa isikhathi eside
Yenziwe ngezinto ze-PVC ezisezingeni eliphezulu nezinobungani nemvelo, iqinile ekubunjweni kwayo, ayithuki futhi ayigugi. Ubuso bayo buphathwa ngenqubo ekhethekile, enemibala ecacile engashisi kalula. Ingagcina ubuqotho kanye nomphumela wokubonisa wemodeli isikhathi eside, okwenza ifaneleke emibonisweni yokufundisa njalo kanye nezimo zokuhlola zelebhu.
Iii. Izimo Ezisebenzayo
- ** Ukufundisa Ngezokwelapha **: Izinkulumo zasekilasini kanye nokuhlolwa kokwakheka komzimba emakolishi nasemanyuvesi ezokwelapha kusiza abafundi ukuba baqonde kahle isakhiwo senhliziyo futhi babeke isisekelo esiqinile sokufunda izifundo zezokwelapha.
- ** Umbukiso Wokuthandwa Kwesayensi **: IMyuziyamu Yesayensi Nobuchwepheshe kanye neMyuziyamu Yokuthandwa Kwesayensi Yezempilo zibonisa ulwazi lwempilo yenhliziyo emphakathini ngendlela eqondakala kalula, okuthuthukisa ukuqwashisa komphakathi ngempilo yenhliziyo nemithambo yegazi.
- ** Ukusekelwa Kocwaningo **: Ocwaningweni lwezifo zenhliziyo nemithambo yegazi, lusebenza njengereferensi eyisisekelo yokwakheka komzimba, lusiza abacwaningi ekuhleleni ubudlelwano phakathi kwesakhiwo nesifo, kanye nemibono yocwaningo ekhuthazayo.
Iv. Amapharamitha Omkhiqizo
- Isikali: 1:5 sikhulisiwe
- Izingxenye: Izingxenye ezintathu ezihlukanisiwe

Imodeli yenhliziyo enezingxenye ezintathu ezi-5, enokubukeka kwayo kobungcweti nokunembile, yakha ibhuloho phakathi kwethiyori kanye nokusebenza, inika amandla ukudluliselwa kolwazi lwezokwelapha kanye nokwanda kwesayensi yenhliziyo nemithambo yegazi. Iwusizo lokufundisa oluthembekile olusezingeni eliphezulu emkhakheni wemfundo yezokwelapha kanye nokwanda kwesayensi.
