Answer 1

The p process by which digested food enters the bloodstream is called absorption.

• Digestion is the process by which food materials ingested by the organism is broken down into simpler substances by the action of various enzymes.
• The final step in the process of digestion is absorption of the digested food by the body. This happens through the blood stream.
• Most sugars are digested in the mouth and the intestines while proteins are digested in the stomach. All these substances are broken into their simplest forms and carried by blood to various parts of the body.
• Fats, which are hard to digest are broken down into chylomicrons in the intestines which is absorbed through the lymph system.

Answer 2

Answer:

The process by which the digested food enters the blood is called Absorption.

Explanation:

• Digestion refers to the process of simplification of complex food by enzymes within the alimentary canal.

• The complex food materials consist of macromolecules that are converted to soluble, diffusible substances i.e. micromolecules to be absorbed in the intestine.

• Absorption is defined as a process by which the digested end products, along with the minerals, vitamins and water enter the bloodstream and lymph from the digestive tract via the mucosa membrane (inner wall) of the alimentary canal.

Hence the absorption of nutrients in food is passed into the circulatory system by the small bristle-like protrusions called villi present in the mucosa
