How to write about the journey of food in the body

The "journey" of food in the body

We need to eat a variety of foods to obtain the nutrients our body needs, maintain normal physiological functions of the body, and absorb what we eat. The process of turning food into nutrients that can be absorbed by the body is digestion.

Let us think of food as a traveler and look at the "journey" of food in our bodies.

Food begins to travel, and the starting point is our mouth. In the mouth, teeth are responsible for chewing food, and saliva is responsible for moistening the mouth and making the food soft, so that we can smoothly sort out the chewed food and swallow it.

Food enters the long esophagus.

The food enters the stomach again. The stomach moves and mixes the secreted gastric juice with the food, turning the food into a paste.

The mushy food enters the long, curved small intestine, which absorbs the nutrients in the food.

The remaining food residues arrive in the large intestine, where the water and other substances are further absorbed and formed into feces, which are then excreted from the body through the anus. Here, the food "trip" ends.

Have you ever heard your belly make a "gurgling, gurgling..." sound? Sometimes this sound is made because your stomach is hungry and the muscles in your stomach squeeze the liquid and gas inside your stomach.
