Digestive akụkụ: gbawara n'etiti ma na-amụta

Mgbaze - a usoro nke anyị na-amaghị ama, na-emekwa ụfọdụ na organism na mpiaji larịị. Usoro a bụ mgbagwoju anya, ya mere ziri ezi ịjụ ịmata onye, "Gịnị bụ mgbaze?". Si ele ihe anya nke dọkịta, ọ bụ nri nhazi, anụ ahụ na chemical. N'ihi ya, ọ na-aghọ omume absorption nke bekee, nakwa dị ka wepụ unyi.
