C O N T E N T S : Basic Information The digestive system contain organs for changing food chemically for absorption by body tissues. It is also responsible for processing food , breaking it down into usable protein, minerals, carbohydrates and fats and other substance. The digestion process involves breaking food into simple soluble substances absorbable by tissues. The digestion process includes both mechanical and chemical processes. The mechanical processes include chewing to reduce food to small particles, the churning action of the stomach, and intestinal peristaltic action. The three Read More Go to Site

The original authors are no longer at the University of Leeds, and the former Centre for Human Biology became the School of Biomedical Sciences which is now part of the Faculty of Biological Sciences . Introductory Anatomy: Digestive System Dr D.R.Johnson, Centre for Human Biology Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and, if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Phys Read More Go to Site

Votes:0 So there you are, sitting at lunch, enjoying some grilled chicken pizza and a few orange wedges. When you're finished, you take a last drink of milk, wipe your mouth, and head to your next class. In a few minutes you're thinking about the capital of Oregon or your science fair project. You've completely forgotten about that pizza lunch you just ate. But it's still in your stomach - sort of like a science experiment that happens all the time! Your digestive (say: dye- jes -tiv) system started working even before you took the first bite of your pizza. And the digestive system will be busy at work on your chewed-up lunch for the next few hours - or sometimes days - depending upon what you've eaten. This process, called digestion, allows your body to get the nutrients and energy it needs from Read More Go to Site

How is food digested? How is the digestive process controlled? The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus ( see figure ). Inside this tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. Two solid organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other organ systems (for instance, nerves and blood) play a major role in the di Read More Go to Site
