Задание 2. Прочтите текст Respiration

In the process of respiration oxygen passes into the blood and carbon dioxide passes into the atmospheric air. The exchange of oxygen and carbon dioxide takes place in the alveoli of the lungs. It is due to the difference of partial pressure of these gases. Hemoglobin is that substance of the blood which transfers oxygen in the blood.

In the process of inspiration the volume of the chest increases and the lungs extend. The pressure in the lungs becomes less and the atmospheric air enters the lungs. In the process of expiration the volume of the chest decreases and the lungs contract. The pressure in the lungs becomes higher and the air goes out of the lungs.

Digestive system

The digestive system is formed by a canal which consists of the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The liver with gallbladder are the large glands of the alimentary tract. The stomach is a dilated portion of the alimentary canal. It is in the upper part of the abdomen under the diaphragm. It has a capacity of from 2 to 4 litres.

Digestive system serves to deliver nutrients to all organs and tissues of our body. The food we eat undergoes a twofold reduction – the mechanical and the chemical ones. The mechanical reduction takes place in the mouth (it is called mastication) and then in the stomach (due to muscular movements). The chemical action is accomplished by the saliva, the gastric juice, the pancreatic juice and the bile. The principal organ of absorption is the small intestine. The useful constituents of food are absorbed by the small intestine, while the useless move into the large intestine
