Условие.

B Study the diagram of the digestive system, then read the descriptions below. Match each description with a word or phrase from the box.

large intestine • mouth • oesophagus

small intestine • stomach

A Once you have swallowed, the food moves down this narrow tube. This tube connects the throat with the stomach. There’s a small trapdoor called a sphincter at the bottom of the tube. It pops open when the food comes down and the food drops into the stomach. The sphincter snaps closed again afterwards.

B This is the place where food gets chewed up and mixed with saliva. Saliva is mostly water, but it also contains enzymes which break down food. It helps make food soft and easy to swallow.

C This is a very important area for digestion. It’s like a big washing machine. The food drops in and the top area expands. If you’ve had a lot to eat, you can really feel it. While the top part is storing the food, the bottom part starts mixing the food up with digestive juices or acid – this is the muscle working to break down the food even more. Then it has to slowly empty its contents out into the next sections.

D When the food gets to this point it doesn’t really look anything like food anymore. More enzyme liquids are mixed with the food here. These liquids come from the liver and pancreas. During the passage through this area the nutrients from the digested food are slowly absorbed into the body through little tiny fingers called villi. This is where the body really gets its fuel from.

E This is where all the waste products go. Some absorption of vitamins and water still takes place here, but this is the end of the road for leftover substances such as fibre.
