These two parts of the system work together to break down food into absorbable units and eliminate the non-digested material as feces. Let's begin by identifying each of the organs in the alimentary canal and the accessory digestive structures. Don't be a digestive hog -- just choose one organ/structure and post details about it -- then the rest of us have something to talk about during these posts BIOS 256 DeVry Week 1 Discussion 2 The Digestive Process - mouth / stomach Digestion is divided into two basic parts: physical digestion and chemical digestion. Let’s begin by defining each type of digestion, discussing the enzymes and fluids introduced into the metabolism of nutrients. How does the organs of the upper digestive system (mouth through stomach) relate to these processes? BIOS 256 DeVry Week 2 Discussion 1 Gastric Juices As we transition between the upper and lower components of the digestive system, let's start out by talking what changes must occur at the transition between the stomach and small intestines to further the digestive process. Each of you should focus on one of the substances secreted at this transition that either neutralizes the chyme from the stomach or takes up where the stomach has left off in terms of chemical digestion (look to proteins, carbohydrates and lipids) BIOS 256 DeVry Week 2 Discussion 2 Large Intestinal Functions There are a variety of roles that occur within the large intestines. In this first posting please focus on one of the roles of the large intestines, explain it, describe the cells that help accomplish this role, and other structures or organisms that contribute to the process.
