1 Digestive System The process of chemically and physically breaking down foods into simpler forms that can be absorbed is called digestion. Digestive System â¢ The digestive system can be divided into two major parts: â (1) the alimentary canal (gastrointestinal, or digestive tract) and â (2) the accessory organs.igestive System Overview â¢ The large intestine is divided into the (1) cecum, (2) appendix, (3) colon, (4) rectum, and (5) anal canal. â The sigmoid colon joins the rectum, which terminates at the anal canal. The short anal canal terminates at the opening to the outside called the anus.
A butterfly is a great example of this, or a sea star. A gastrovascular cavity is a digestive sac with only a single opening. An alimentary canal has two openings (a mouth and anus) between its digestive tubes unlike the gastrovascular cavity in which food is ingested and eliminated through the same opening.ilateral symmetry: An arrangement of body parts such that an organism can be divided equally by a single cut passing longitudinally through it. A bilaterally symmetrical organism has a mirror-image right and left sides.
