A handy of free and printable human digestive tract diagrams has been collected and are available for you in high definition! The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body and eliminates unused waste material. It is essential to good health because if the digestive system shuts down, the body cannot be nourished or rid itself of waste. To help you understand how the many parts of the digestive system work together, here is an overview of the structure and function of this complex system.
In the digestive tract, that group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Like what you can observe in the following digestive tract diagrams.
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins. The digestive tract includes the mouth, the esophagus, the stomach, the small and large intestines, and the rectum.
