Paraphrase the thesis sentence. Summarize the main steps of the process. Groups of organs, such as the mouth, esophagus, stomach, and intestines, work together to perform this complex task. Digestion is theprocess of breaking down food from large molecules into small ones to makeit easier for absorption.
The three major steps involved in the digestive process are ingestion, digestion, and absorption. Ingestion, 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, a valve lets the food enter the stomach.
Contraction of the stomach wall mixes the food.
Acidic gastric juices, which are secreted by the gastric glands in the stomach, help in mixing the food and in turning it intoa partial liquid so it will have the ability to move into the small intestine. In the small intestine, enzymes are secreted, and digestion is completed.
The last step in the digestive process is absorption. Absorption takes place in the small intestine. The wall of the small intestine is lined with small, finger like projections called villi.
Small molecules of food are absorbed by the huge number of villi. Someof these absorbed molecules enter the bloodstream to be distributed throughout the whole body. In conclusion, the digestive process involves three major steps: Ingestion, which occurs in the mouth, helps to increase the surface are of the food particles and prepares them for digestion.
In the stomach, digestion begins, and it continues until it reaches the small intestine, where absorption takes place. The digestive process maintains organisms' lives by providing them with energy needed for different functions.Try Our Friends At: The Essay Store.
