Must first be broken down into smaller units before it can be absorbed by the intestinal wall cell

Nutrients in food must first be broken down into smaller units before it can be absorbed by the intestinal wall cell.

Explanation:

The food we eat is always broken down into smaller substances by humans with the help of their teeth in  mouth so that it will be easier for them to chew the food through the food pipe.

Also it will be easier for digestion as nutrients are split into smaller portions which makes the process in the intestine easier. Whereas liquids are swallowed by humans which will easily travel through the digestive systems. These nutrients are called as macromolecules which consists Proteins, carbohydrates, nucleic acids, and lipids.
