Human digestive system explained to kids
The human digestive system is a long, coiled tube that starts at the mouth and ends at the anus. Along the way, it goes through the esophagus, stomach, small intestine, and large intestine. The digestive system is important because it helps the body break down food so that the nutrients can be used by the cells.
The digestive system is made up of several different parts, including the mouth, teeth, tongue, esophagus, stomach, small intestine, large intestine, and anus. Each part has a different job to do in order to break down the food.
The mouth is the first part of the digestive system. The teeth in the mouth chew the food and the tongue helps to move it around. The saliva in the mouth also helps to break down the food.
The esophagus is the tube that goes from the mouth to the stomach. The esophagus squeezes the food down so that it can fit into the stomach.
The stomach is a sac-like organ that stores the food and helps to break it down. The stomach makes acid that helps to break down the food even more.
The small intestine is a long, coiled tube that is about 20 feet long. The small intestine is where most of the food is broken down into nutrients. The small intestine also absorbs the nutrients into the bloodstream.
The large intestine is a shorter, coiled tube that is about 5 feet long. The large intestine absorbs water from the food that is left over. The large intestine also stores waste material until it is ready to be eliminated from the body.
The anus is the end of the digestive system. The anus is where the waste material is eliminated from the body.
