Taught by Professor Anthony A. Goodman | 44 min | Categories: The Great Courses Plus Online Science Course
Having studied the anatomy of the mouth, esophagus, and stomach, we turn now to the processes of digestion, absorption of nutrients, and excretion of waste products. This lecture examines mechanical then chemical digestion. Next, we examine the three phases of gastric secretion, and the process of gastric emptying. Finally, we consider stomach and digestive disorders and their treatments.
