Transcript
DIGESTIVE SYSTEM Food contains complex substances which the body breaks down into simpler particles. It takes place in your digestive tract which is like a long tube running from your mouth to your bottom (anus). In your mouth the teeth break down food into chunks. The salivary glands produce saliva which contains an enzyme called ptyalin. Ptyalin converts starch into dextrine and maltose. No digestion occurs here. It links your throat to the stomach. The esophagus pushes food into the stomach through a muscle movement called peristalsis It’s a muscular bag that stores food and breaks down proteins and lipids. The stomach kills a lot of bad bacteria. It works with the juice coming from the liver and pancreas to break down food. Nutrients pass to the blood through the intestine walls. It accepts what small intestine doesn’t need or can’t use and later leaves the body as waste. Rectum is the last part of the large intestine and stores feces before it is expelled.
