Human akụkụ nke mgbaze

Digestive akụkụ a onye na-arụ otu n'ime ya kasị mkpa n'ahụ ọrụ - eri nri, tọghata ya ume, ntọhapụ nri na-egosipụta ahụ wastes. Rịba ama na a niile na ọrụ na-nwere njikọ chiri anya na ịrụ ọrụ nke ndị ọzọ ngwa na sistemụ na-arụ ọrụ were were. Ka ihe atụ, na usoro nke na mgbaze akụkụ ikere òkè dị ukwuu nke ọbara usoro nke mmadụ - ha na-n'ụba onwem na ihe nile nke digestive usoro. Mgbe ọbara nile na-akawanye nri bekee na-eburu ha ofụri idem.

mmadụ digestive usoro nwere ike kewara abụọ ụdị - isi na sekọndrị. Ihe bụ isi na-ndị na-ejikọta ya na n'ikuku, na gbarie nri ndọrọ ego si ahụ.

Ọdịdị nke ahụ mmadụ na digestive akụkụ bụ oké ike, n'ihi na nke ha ọrụ. Malite digestive usoro na-edeghị ede oghere - ebe a emee isi machining ezé na nri precipitated asu. Parotid asu ntọhapụ, sublingual na submandibular emepụta asọ mmiri. Site na iji enzymes, nke na-ẹdude ke asu, gbarie nri-amalite ugbua na ọnụ - na-akpọ mbụ hydrolysis usoro nke gbarie carbohydrates. Next nri abatakwa akpịrị, na mgbe ahụ n'ime ndị na nkọlọ. The na nkọlọ bụ ogologo tube na-ejikọ ndị uzo mmiri na afo-nche ọnụ muscle, egbochi nri gbatara azụ n'ime nkọlọ.

Mgbe nri mechaa ndị dị mkpa nhazi ke afo, ọ na-aga n'ime eriri afọ.
