Science Subject for High School - 9th Grade Human Body. Digestive System

From the mouth through the esophagus into the stomach and passing through the small and large intestine and secreted by the anus. The journey of a piece of food takes many steps in our digestive system. Teach your students all about this system and the organs that take part in digestion, as well as the pancreas, liver or gallbladder, with these slides filled with illustrations of the human body and its organs. Show them where they’re located and their important functions in our lives.
