The Digestive System
This pathway provides an in-depth look at overview of the digestive system, digestive system processes & regulation; the mouth, pharynx, & esophagus; the stomach; the small & large intestines; accessory organs in digestion: the liver, pancreas, & gallbladder; and chemical digestion & absorption: a closer look. The pathway also provides vocabulary support for these topics, as well as opportunities for learners to self-assess their understanding by analyzing figures and answering questions.
