What are the steps of food digestion?

The first part of food digestion is actually happening in the mouth. People's teeth and saliva work together to start the process of breaking food. Generally, they also help to get into size and consistency, which can be easily managed by the rest of the system. Then the muscles promote the food through the esophagus into the stomach, where acids and other substances turn food in a porridge called Chyme. The small intestine takes the resulting porridge created in the stomach and absorbs nutrients from it, after which it is passed to the large intestine of a person, where it turns into feces before exclusion from the rectum.

Some scientists compare the human body with a machine and digestion can be considered the way it processes energy. Food is full of energy that can be potentially used to keep the body running, but this energy is not easily accessible without turning it into something that can be easily absorbed. People spend different nutrients at different speeds using slightly different processes and each nutrient is used in their own way. Protein is primarily used to repair the body while uHogs and fat are used primarily as fuel.

The chewing process is more organized than many people are aware of, and it is generally a key part of food digestion. The saliva itself has many chemicals that can spend food, and also helps to moisten food to easily swallow. When people chew, they actually create food into small pieces that are perfectly large to make them easy to enter the stomach. When food enters the stomach, food is already in place, partly because it is saturated with digestive chemicals of saliva before stomach acid even starts to work on it.

Human stomach has muscles that presses food and spews, which is essential for the process of food digestion. Food that lasts a longIGEST, such as protein, tends to remain in the stomach much longer than faster revealing foods such as carbohydrates. The process of natural digestion of the acornThis causes this to happen without special mechanisms. The stomach also has the ability to absorb some nutrients, even if it is not his primary work.

The small intestine is relatively long and shaped as a tube. It helps to start the process of shaping food into something that can later be excluded. It is also the main place where nutrients are absorbed.

6 Once the food leaves the small intestine, it is basically through digestion. For expulsion, they must simply be packed as feces.
