Functions and Roles in Digestion

The video covers animal nutrition, focusing on the small intestine's role in digestion and absorption. It explains the functions of the liver, gallbladder, and pancreas, highlighting the production of bile and digestive enzymes. The pancreas's role in secreting enzymes and bicarbonate to neutralize stomach acid is detailed. The video also discusses the breakdown of carbohydrates, proteins, nucleic acids, and fats, emphasizing the importance of various enzymes in these processes. Finally, it touches on the liver's detoxification function.
