Human Digestive system includes Gastrointestinal Tract and other accessory parts like the liver, intestines, glands, mouth, stomach, gallbladder. There are 6 main functions of the Human Digestive System Process: Ingestion, Motility, Secretion, Digestion, Absorption, Excretion. The food that you eat gives you not only the required energy and nutrients to the body but also is used for cell growth and repair
In Human digestive system, there are many parts that work together. The food that you eat has biomacromolecules, which are nothing but the carbohydrates (such as sugars), proteins, lipids (such as fats), and nucleic acids. These have to be converted to their simpler forms so that your body can absorb it. These biomacromolecules are the building blocks that you require to maintain your body, which is also made of these large biological molecules, along with water!
This process of converting complex food substances (molecules) into simpler forms to facilitate absorption is called Digestion. In humans, this system consists of many parts and organs, including the alimentary canal, digestive glands, and a few accessory organs such as the teeth, salivary glands, tongue, pancreas, liver, gallbladder etc.
Nevertheless, the starting point where digestion actually starts in the mouth! From the mouth, it passes through the alimentary canal, which is also called the gastrointestinal tract. This tract consists of the pharynx, esophagus, stomach, small intestine, large intestine, and anus. The mouth can be considered as the anterior opening of the alimentary canal, while the anus is the posterior opening.

Digestive System Process:
From the Mouth to the Large Intestine and Anus. The Human digestive system process can be divided into stages, namely:
Ingestion
Motility
Secretion
Digestion
Absorption
Excretion
The whole process starts in the oral cavity, where the saliva from the salivary glands mixes with the food and starts to begin the breakdown of food. From the mouth, the food passes to the hollow tube-like organ the esophagus. From the esophagus, food then travels to the stomach, where it breaks down further with the help of the acids and powerful enzymes secreted by the stomach.
