Which organ directly after the stomach in the GI tract order?

• A. Pharynx
• B. Esophagus
• C. Rectum
• D. Small Intestine

Answer: (D)

In the path food travels through the digestive system, the stomach hands chyme to the small intestine via the pyloric sphincter. The next major section after the stomach is the small intestine, where most digestion and nutrient absorption occur. Chyme mixes with bile and pancreatic enzymes in the first part of the small intestine (the duodenum) to continue breaking down fats, proteins, and carbohydrates, and nutrients are absorbed as it moves through the jejunum and ileum. The pharynx and esophagus come earlier in the route, carrying food to the stomach, while the rectum is at the end of the digestive tract. The small intestine comprises the duodenum, jejunum, and ileum, with the duodenum being the primary site where digestion mixes with bile and pancreatic juice.
