The process of breaking down large food particles into smaller and water-soluble particles, which can be easily absorbed by the blood plasma is called:

Digestion is the term used to signify the breaking down of complex food materials into simpler forms for easy absorption. The digestion process begins in the mouth, where the teeth cut down the food into smaller pieces, and the tongue mixes saliva with it. Partial digestion of starch starts in the mouth and is continued in the stomach and intestine along with digestion of other substances like protein and fat. The digested food consists of soluble particles like glucose and amino acids, which get absorbed into the blood plasma and utilised for the body’s energy needs. Absorption completes the digestion process.
