Digestive system. Illustration of the components of the human digestive system or alimentary canal,as positioned naturally over a silhouette of the human body. At top,the oesophagus is a muscular tube which leads from the mouth to the stomach. In the stomach (kidney-shaped,pink) food is digested and it passes into the duodenum (C-shaped tube) for further chemical breakdown. The gall bladder (grey bulb) secretes bile enzyme into the duodenum while the pancreas (yellow) secretes a pancreatic enzyme. Digested food then passes into the small intestine (pink) and large intestine (brown) where nutrients are absorbed into the body. The liver (purple,top) metabolises nutrients in the blood | |
