This resource explores the stages of food processing in the digestive system, focusing on ingestion, digestion, absorption, and elimination. The first stage, ingestion, involves the mouth and oral cavity. The second stage, digestion, occurs in the stomach. The third stage, absorption, takes place in the small intestine, while the fourth stage, elimination, involves the colon and rectum. Essential nutrients including amino acids, vitamins, and their roles in maintaining health are also discussed, providing a comprehensive overview of animal nutrition.
