After food is chewed it takes 5-10 seconds for it to pass down the esophagus and into the stomach, where it spends 2-6 hours being partially digested. Final digestion and nutrient absorption occur in the small intestine over a period of 5-6 hours. In 12-24 hours, any undigested material passes through the large intestine, and feces are expelled through the anus.
Digestion is a biological process that existed long before humans did. Nobody invented it.
This process is called digestion.
This is a digestion process in the absence of oxygen. This process however do not take place in the living body.
Digestion
The process of changing food to substances that can be used by the body is known as digestion. In the average adult, the whole process of digestion takes about 50 hours.
Digestion is the process of breaking down food into simpler substances. Digestion is of two types: mechanical or physical digestion, and chemical digestion.
The enzyme amylase breaks down starch in the process of digestion.
The digestion of carbohydrates (starches and sugars) and of protein is so different, that when they are mixed in the stomach they interfere with the digestion of each other. An acid process (gastric digestion) and an alkaline process (salivary digestion) can not be carried on at the same time in an ideal way in the stomach. In fact, they cannot proceed together at all for long as the rising acidity of the stomach contents soon completely stops carbohydrate digestion and this is followed by fermentation.
The digestion process begins in the mouth.
The chemical equation for the process of digestion is: Food Digestive Enzymes Nutrients Waste Products
