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.
Function: Chemical digestion of food and absorption of nutrients into your blood. Longest section of your digestive tract. Your small intestine is around five metres long, making it the longest section of your digestive tract. Although it is longer than your large intestine it has a smaller diameter. This is why it's called the small intestine. Chemical digestion. After food is churned up in your stomach, a sphincter muscle at the end of your stomach opens to squirt small amounts of food into the top of your small intestine. This first section of the small intestine is called the duodenum. Your pancreas releases digestive juices through a duct into your duodenum. This fluid is rich in enzymes that break down fats, proteins and carbohydrates. It also contains sodium bicarbonate which neutralises acid produced in your stomach.
