Question

Quizplus · Accepted Answer

The small intestine is divided into three regions: the duodenum (which receives food from the stomach and mixes it with bile and pancreatic juices), the jejunum (where most of the nutrient absorption takes place), and the ileum (which connects to the large intestine and absorbs remaining nutrients and water). Therefore, the correct answer is A (ileum). B, C, and D are incorrect because the cecum is part of the large intestine, the rectum is part of the digestive system but not the small intestine, and the anus is the exit point for waste materials from the digestive system.
