What is Egestion?
Egestion Definition: Egestion is the process of expelling waste or undigested substances from a cell or the digestive system of multicellular organisms.
In the complex species, egestion is a voluntary process that happens through the anus. In single celled organisms, egestion happens through cell vacuoles. Egestion marks the end of digestion process. Once nutrients are absorbed in the small and large intestines the undigested food exits through the anus.
Egestion in Simple and Complex Species
Egestion is the final step of digestion. It is a process of removing waste material from an organism. For simple species, egestion happens when cell vacuoles collect unwanted food and materials from the cells. After that, they fuse it with the cell membrane. The cell membrane then breaks down and the waste materials are released outside of the body.
In complex animals, the waste materials are transformed into poop and temporarily stored in the rectum, and then expelled through the anus. In this article, we are going to discuss Egestion in Simple and Complex Species in detail.
