The digestive system is composed of organs that work together just to metabolize energy from the food for the body. The human digestive system and nutrition are concerned with an organism's food intake and energy usage. This is an important mechanism that allows living things to get energy from a variety of sources. The food we consume is processed substantially before the nutrients in it are used for energy production.
Digestion involves the food channel with several auxiliary organs as well as organ systems. The gastrointestinal tract and auxiliary organs, including the liver, pancreas, and gallbladder, make up the digestive system anatomically. The food we consume is processed extensively before the nutrients in it are used for energy. This is called the digestive system process.
A collection of organ systems working together to turn food into energy as well as other essential nutrients to power the body is the role of the human organ in the digestive system. The human body's digestive system consists of the sum of the gastrointestinal tract (GIT) and accessory organs. In the digestive process, both sections contribute simultaneously. Let us take a comprehensive look at the digestive system and its parts and functions of the human body:
The digestion process starts from the mouth and extends up to the small intestine. The primary role of the liver is to extract undigested food's water. Bacterial fermentation of nondigestible materials is made possible with their help. Food passes through the alimentary canal, a system of hollow organs and tubes extending from your mouth cavity to your stomach, small and large intestines, and ends at the anus. While travelling through the gastrointestinal tract, food particles slowly begin to be digested as they pass through the various compartments.
The following steps are involved in the digestion process. Six steps make up the digestion process:
2. Mixing and Movement
The first phase is mastication (chewing). Then, food is lubricated and moistened using the salivary glands and tongue before entering the food pipe.
This procedure lubricates and manipulates foods before pushing them down the food pipe via peristalsis and into the stomach.
Digestive enzymes and acids are secreted by the stomach, small intestine, liver and pancreas. When it is activated, it breaks down food particles into efficient and easily absorbed components.
Complex food materials are broken down by enzymes and acids produced naturally by various digestive organs.
In the small intestine, the majority of nutrients and minerals are collected. The large intestine is responsible for the absorption of any surplus water found in the indigestible substance.
Indigestible components and waste byproducts are removed from the body via defecating.
Digestion is required to absorb the nutrients utilized by the body like an energy source, cell preparation and development and the body has various parts or organs that play their unique role to obtain these nutrients from food.
