Dab tsi yog qhov txawv ntawm Ingestion thiab Egestion?
Definition of Ingestion and Egestion:
Kev Noj Qab Haus Huv: Kev noj mov yog txheej txheem ntawm kev noj zaub mov rau hauv lub cev.
Kev Tshaj Tawm: Egestion yog tshem tawm cov khoom pov tseg ntawm lub cev.
Yam ntxwv ntawm Kev Noj Qab Haus Huv thiab Egestion:
organs:
Nyob hauv ntau cov kab mob ntau yam, Kev Noj: Kev noj mov tshwm sim ntawm qhov ncauj.
Egestion: Egestion tshwm sim ntawm lub qhov quav.(tsuas yog cov neeg uas muaj plab zom mov tag)
Order:
Kev Noj Qab Haus Huv: Kev noj zaub mov yog thawj txheej txheem ntawm plab hnyuv, egestion yog txheej txheem kawg ntawm nws.
Kev xav: Egestion yog txheej txheem kawg ntawm nws.
Function:
Kev noj: zaub mov thiab dej tau noj los ntawm kev noj, Kev xav: quav tawm los ntawm egestion.
