Tracing Exercises MATERIALS the human outline af water soluble body marking pens Now it's time to put all of the digestive anatomy and physiology together to get a "big picture" view of the digestive system. In this exercise you will trace the pathway that three different nutrients take from their ingestion at the mouth to their arrival at the heart. You will trace a cookie (primarily bohydrates), an egg (primarily protein), and a greasy french fry (primarily lipids). Along the way, detail the following for each: 1. The anatomical pathway that each takes, from ingestion through its passage through the alimentary canal, to its absorption into the blood, and finally to its passage through the blood until it reaches the heart. 2. The physical and chemical processes that break down each substance, including enzymatic breakdown, churning, chewing, and emulsification. Don't forget that most nutrients travel through the hepatic portal system before they enter the general circulation Remember that digestion and absorption are quite different for lipids. For example, fats are not absorbed into the intestinal blood capillaries. Use your list of enzymes that you completed in Pre-Lab Exercise 23-3 for reference. Refer to the tracing exercises from Unit 17 (p. 201-203) and Unit 20 (p. 234) to review the pathway of blood and lymph flow through the body.

Answer 1

"Amino acid transfer to liver through hepatic portal From liver amino acid inters in heart through inferior venacava. French fry flow: - in mouth no digestion of fat. In stomach there is no digestion of fat. In intestine nearly 80
