What is Digestion?
The process of breaking down food molecules into smaller particles and converting complex food substances into simple absorbable forms is termed as the Digestion.
What is Absorption?
Absorption process is Chiefly involved in the movement of digested food molecules across the gastrointestinal (GI) tract to the circulatory system.
Both digestion and absorption are an important process, as it helps in breaking down different types of nutrients, including carbohydrates, fats, minerals, proteins and vitamins into its simpler forms so that it can be absorbed easily into the body cells.
