The food which we eat includes different types of macro and micronutrient. These food molecules play an essential role in our growth and development. Digestion and Absorption are the two main process which are involved in the digestion and movement of the food molecules to their respective organs.
The process of breaking down food molecules into smaller particles and converting complex food substances into simple absorbable forms is termed as the Digestion.
The absorption process is mainly involved in the movement of the digested food molecules across the gastrointestinal (GI) tract into the circulatory system.
Both digestion and absorption are an important process, as it helps in breaking down different types of nutrients, including the carbohydrates, fats, minerals proteins and vitamins, into its simpler forms so that it can be absorbed easily into the body cells. During this process, proteins are converted into amino acids, carbohydrates are converted into sugars and fats are broken down into fatty acids and glycerol. The whole process of digestion occurs in a sequential manner.
The human digestive system plays an important role in digestion and absorption of food molecules. The first step of digestion begins with ingestion, a process where food is taken in through the mouth and broken down by teeth and saliva. And then followed with digestion and absorption.
In this process, a complex series of organs and glands are involved in converting huge components of food molecules to simpler and into an absorbable form. These glands include:
- Digestive Glands – Salivary glands, Gastric glands, Intestinal glands, Pancreas and Liver.
- Small Intestine.
- Large Intestine.
