Exploring the Digestion Process

The video explains the process of digestion, starting from the mouth where saliva begins breaking down food. It then moves through the esophagus to the stomach, where gastric juices further digest the food. The small intestine continues the process, absorbing nutrients with the help of the pancreas, liver, and gallbladder. Finally, the large intestine absorbs water, forming waste for excretion.
