What is Ingestion, Digestion, Absorption and Assimilation?
Dear Student,
Here is the answer to your question,
Ingestion: The process of taking in food through the buccal cavity is known as ingestion.
Digestion: It is the process of breaking down food into simpler substances.
Absorption: The process of absorption takes place in the small intestine. Here, the digested food is absorbed in the blood through the villi, which are sac-like structures.
Assimilation: The food absorbed by blood is transported to various parts of the body by blood vessels. This process is known as assimilation.
Egestion: The process of removing the undigested food material from the body through the anus is known as egestion.
Hope it is clear to you now,
Cheers!!
