A PROCESS OF DIGESTION

A PROCESS OF DIGESTION The digestive process is important in maintaining the lives of living organisms and in providing them with needed energy, Groups of organs, Os the mouth, esophagus, stomach, and intestines, work together to form this complex task. Digestion is the process of breaking down food pelarge molecules into small ones to make it easier for absorption. The es major steps involved in the digestive process are ingestion, digestion, and absorption. tngestion, which occurs in the mouth, is the first step of the digestive process. After food enters the mouth, the teeth chew it. Saliva, which is produced by the salivary glands, plays a major role in breaking down the food into smaller pieces. These small pieces travel to the stomach through the esophagus. In the stomach, the second step of the digestive process begins when the chewed food reaches the bottom of the esophagus.
