The Digestive System

Mr. Andersen's podcast explores the digestive system, starting with different feeding types in animals. He uses a donut analogy to explain how food moves through the digestive tract. The podcast covers the breakdown of macromolecules like carbohydrates, proteins, lipids, and nucleic acids. It details the roles of the stomach, duodenum, pancreas, and intestines in digestion and absorption. The appendix is discussed as a vestigial structure. The podcast concludes with a review of where digestion occurs for each macromolecule.
