Exercise 3. Translate into Ukrainianthe respiratory system, spongy air-filled organs, muscles of respiration, the lateral cavities of the chest, to be covered with the pleura, conical in shape, the weight of the lungs, the vital capacity of the lungs, to consist of three lobes, to be of a pale rose colour, to become darker, the capillaries of the lungs, gas exchange in the lungs, the total surface, to provide with oxygen, to remove carbon dioxide
Grammar. One/ones, that/those
Exercise 4. Translate into Ukrainian. Pay attention to the use and translation of one/ones, that/those 1. The right atrium is larger than the left one. 2. The number of the vertebrae in the coccyx is less than the number of those in the neck. 3. The lower lobe of the left lung is larger than the upper one. 4. The bones of the lower extremities are longer than those of the upper ones. 5. The weight of the lung is less than that of the heart. 6. Which dictionary do you want? This one or that one? Exercise 5. Read the text. Write out the key words and word-combinations The Lungs There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The lungs are the main organs of the respiratory system. There are two lungs in the human body. They are spongy air-filled organs located in the lateral cavities of the chest. The lungs are separated from each other by the mediastinum. The lungs are covered with the pleura. They are conical in shape. Each lung has the base, apex, two borders and three surfaces. The weight of the lungs varies according to many conditions. In the adult male the weight of the lungs is about 1,350 gr. The right lung is about 15% heavier than the left one. Vital capacity is the maximum volume of air that a person can exhale after maximum inhalation. The vital capacity of the lungs is 3.5-4 liters in the male and it is 3-3.5 liters in the female. The right lung consisting of three lobes is heavier than the left one because the latter consists only of two lobes. The lower lobe of the left lung is larger than the upper one. In infants the lungs are of a pale rose colour, but later they become darker. Alveoli are the functional units of the lungs that permit gas exchange between the air in the lungs and the blood in the capillaries of the lungs. The lungs have many capillaries with the total surface of about 80 sq.m. The lungs provide us with vital oxygen and remove carbon dioxide before it can reach hazardous levels.
Exercise 6. Answer the questions 1. What are the major parts of the respiratory system? 2. What kind of internal organs are the lungs? 3. Where are the lungs located? 4. What do the lungs consist of? 5. What is the weight of the lungs? 6. What is the vital capacity of the lungs in the male and in the female? 7. How many lobes do the lungs consist of? 8. What is the functional unit of the lungs? 9. What is the function of the lungs?
