In this episode, we'll break down the intricate processes of nutrient digestion and absorption, from the mechanical and chemical digestion in the stomach to the vital role of the small and large intestines. We'll also discuss the regulatory mechanisms involving hormones and nervous innervation and the essential structures like the liver, gallbladder, and pancreas. And don't forget, this episode is packed with tips on everything you need to know about this high-yield topic for the MCAT.

So grab your notes, get comfortable, and let's embark on this fascinating journey through the digestive system. Stay tuned for a deep dive into how our bodies turn food into the vital nutrients we need to thrive.
