Chapter 3: Nutrients in the Body
You probably do not think too much about what actually happens to the food you eat after you eat it. This chapter will describe in depth how what you eat is digested. We’ll start with an introduction to some basic biology of the body, and then take an in-depth tour through the digestive tract and its workings.
Sections:
3.1 Basic Biology, Anatomy, and Physiology
3.7 Digestive Hormones, Accessory Organs, and Secretions
