All Rights Reserved Digestive Compartments (소화 구획) • Most animals process food in specialized compartments (대부분의 동물은 특수한 공간에서 음식을 처리함) • These compartments reduce the risk of an animal digesting its own cells and tissues (이러한 구획은 동물이 자신의 세포와 조직을 소화할 위험을 줄여줌) Copyright © 2021 Pearson Education Ltd.
