What is the anatomy of the digestive system?

The anatomy of the digestive system is designed to move food through the body, process it for energy and absorb important vitamins and minerals along the path. The path that food takes is called the digestive tract. The body begins to digest food in the mouth, then moves it through the esophagus, stomach, small intestine and large intestine, and eventually the waste eliminates the rectum. The liver, pancreas, gallbladder and parts of the nervous system and circulatory system also play smaller roles in digestion, but are therefore considered part of the anatomy of the digestive system.

The food that enters the mouth immediately begins to crumble due to saliva, secretion of salivary glands. The teeth break food into digestible parts and saliva contain enzymes that begin to decompose carbohydrates. The tongue helps to move the food around the mouth and eventually push it to the back of the neck to swallow.

As soon as the person swallows, the involuntary process of movement begins with the digestive tract and the process is facilitated by the muscle structure built into parts of the anatomy of the digestive system.From the mouth, food enters the esophagus, which is a pipe from the mouth to the stomach. Its walls have muscles that can expand to some extent and to some extent to allow larger and smaller pieces of food to be allowed. At the end of the esophagus is a sphincter of the esophagus, which is gate to the stomach.

6 The enzymes and hydrochloric acid foods continue to break the food and spew it on a liquid called Chyme. The muscles in the stomach wall keep food in motion and slowly pour it into the small intestine.

The small intestine is the longest part of the anatom meter system. It is approximately 24 feet (7.3 m) and connects the stomach with the large intestine or large intestine. The muscles in the walls of the small intestine keep food moving by a process called peristalsis. While inside the small intestine, the food further decomposes and energy and nutrients are absorbed by the intestinal wall and into the bloodstream. Juice from other organs, such as abdominal and liver, also migrate the intestinal wall to make digestion easier.

the large intestine is about one fifth of the length of a thin roofVA, but has a larger diameter. The walls of the large intestine continue to absorb nutrients, but leave the rest in the form of by -products of the digestive process. This waste, called feces, can then be excluded from the body by moving the intestine.
