To live and grow, we take food. For the body to use it, it must undergo a series of chemical and physical changes. This process is called food digestion.

Digesting starts by putting food in the mouth, chewing and swallowing. It is done in a digestive system.

All parts of this system are interrelated, and differ in their actions. It goes out of the mouth into the throat, which serves as a passage of food and air, and then into the esophagus, which connects the throat with the stomach.

The stomach continues to the duodenum, which passes into the small intestine. The digestive system ends with a large intestine and anus.

The spit in the mouth helps to dispel starch which is, for example, found in potatoes or grains – the ingredients of the food we take. When the food in the mouth is moist, softened and slim, it goes down the throat and along the esophagus and then enters the stomach. Most of the process of digestion is carried out there.

StomachGastric juices, which excite the glands in the stomach wall, are mixed with food. Salt (hydrochloric acid) is one of the gastric juices, and there is still pepsin, which helps the growth of protein chewing on more complex ingredients and thus speeds up digestion.

The starch is also stirred with juices for digestion and when the food passes into the liquid state, it is ready to pass from the stomach into the duodenum, through the opening in the bottom final section of the stomach called the pylorus.
