Learn about the three parts: the duodenum, where most digestion occurs, the jejunum, where nutrients are absorbed, and the ileum, where important vitamins are absorbed. Discover the role of villi and microvilli in increasing surface area for digestion.

It details how amino acids, sugars, nucleosides, and fats are transported into cells using primary and secondary active transport. The video also highlights the role of ATP and ion gradients in this process.
