Students could sequence the digestive system as they read through the site. This will give them the big picture. Once at the activity, students should review what they've learned by clicking on the link, "Building Your System. As the benchmark for this lesson states, it's important for students to realize that the indigestible parts of food are eliminated and that people obtain energy and materials for body repair and growth from food. To continue to illustrate these ideas, students should follow the final link on The Learning Site, "Food Path.
In addition, assess student understanding of the digestive system by how well they recreated the digestive system in the Development, after reading the KidsHealth article.

I have 3 other exercise physiology books. This book is by far the best one. I learned about it from my Advanced Nutrition and Human Metabolism book by Gropper which is a superb nutrition book. I only wish I had known about this book before buying the others over the years. I highly recommend this book. I have not read another exercise physiology textbook that more successfully balances depth and relevant applications.

Our class needed this as a reference! It has been great! The rate of emptying of the stomach depends upon the physical and chemical composition of the meal. Fluids empty more rapidly than solids, carbohydrates more rapidly than proteins, and proteins more rapidly than fats. When food particles are sufficiently reduced in size and are nearly soluble and when receptors in the duodenal bulb the area of attachment between the duodenum and the stomach have a fluidity and a hydrogen ion concentration of a certain level, the duodenal bulb and the second part of the duodenum relax, allowing emptying of the stomach to start.
During a duodenal contraction, the pressure in the duodenal bulb rises higher than that in the antrum. The pylorus prevents reflux into the stomach by shutting. The vagus nerve has an important role in the control of emptying, but there is some indication that the sympathetic division of the autonomic nervous system is also involved.
Several of the peptide hormones of the digestive tract also have an effect on intragastric pressure and gastric movements, but their role in physiological circumstances is unclear.
The small intestine is the principal organ of the digestive tract. The primary functions of the small intestine are mixing and transporting of intraluminal contents, production of enzymes and other constituents essential for digestion, and absorption of nutrients. Most of the processes that solubilize carbohydrates, proteins, and fats and reduce them to relatively simple organic compounds occur in the small intestine.

As the embryo folds off, the endoderm is rolled in as the foregut and hindgut. Continued growth progressively closes both the midbody and the midgut.
