Verified step by step guidance1
Begin by understanding the context of the digestive system, which involves the breakdown and absorption of food.
Identify the role of the stomach in digestion, which includes mechanical and chemical processing of food.
Recognize that chyme is the result of this stomach processing, where food is mixed with gastric juices to form a semi-fluid mass.
Understand that chyme is then expelled from the stomach into the duodenum, the first part of the small intestine, for further digestion and nutrient absorption.
Differentiate chyme from other digestive components such as hormones, bile, and enzymes, which have distinct roles in digestion and metabolism.
