How does the digestive system work?

Digestion is a vital process in humans, which provides energy by breaking down the large food molecules into easily absorbable molecules to produce energy for various life processes.

The complete process of digestion in Human digestive system is described below: 1 Ingestion: It is the process of us ingesting the food by eating it. In the mouth the food material is subject to cutting, tearing, chewing, and a little bit of digestion using the salivary juice and finally swallowing. 2 Digestion: It is the breakdown of the ingested food into microscopic and finally molecular fragments. Digestion occurs in the oral cavity, stomach and in the small intestine. 3 Absorption: This is a critical stage where nutrients are taken up from digestive organs and distributed to the body’s tissues. This process is where food ingested is converted to actual energy to be used by our bodies. 4 Excretion: This is the final process where waste material is excreted from our bodies.
