34. Translate at sight. Amazing Facts about the Respiratory System:

• The right lung is slightly larger than the left one.

• Hairs in the nose help to clean the air we breathe as well as warming it.

• The highest recorded "sneeze speed" is 165 km per hour.

• The surface area of the lungs is roughly the same size as a tennis court.

• The capillaries in the lungs would extend 1,600 kilometers if placed end to end.

• We lose half a liter of water a day through breathing. This is the water vapor we see when we breathe onto glass.

• A person at rest usually breathes between 12 and 15 times a minute.

• The breathing rate is faster in children and women than in men.

• Your lungs contain almost 1500 miles of airways and over 300 million alveoli.

• Every minute you breathe in 13 pints of air.

• Plants take in carbon dioxide and release oxygen. Plants are our partners in breathing. We breathe in air, use the oxygen in it, and release carbon dioxide.

Ex. 36. Use the medical terms instead of the definitions.

1. The two main air passages into the lungs.

2. Voice box.

3. Covering the lung and lining the chest cavity, this membrane has 2 thin layers.

4. Air spaces within the skull.

5. Area of the brain that controls breathing.

6. Interior area of the nose; lined with a sticky mucous membrane and contains tiny, surface hairs called cilia.

7. These muscles help move the diaphragm up and down for breathing.

8. Bones attached to the spine and central portion of the breastbone, which support the chest wall and protect the heart, lungs, and other organs in the chest.

9. The main muscle used for breathing; separates the chest cavity from the abdominal cavity.

10. The muscular organ that pumps blood throughout the body.

11. Located at the entrance of the nose, these hairs trap large particles that are inhaled.

12. Thin sheets of muscle between each rib that expand (when air is inhaled) and contract (when air is exhaled).

13. A flap of cartilage that prevents food from entering the trachea (or windpipe).

14. Tube through which air passes from the nose to the lungs (also known as the windpipe).

15. The tube through which food passes from the mouth down into the stomach.

16. The throat.

17. Pulmonary arteries carry deoxygenated blood from the heart and lungs;

18. pulmonary veins carry oxygenated blood back to the heart.

19. The two organs that extract oxygen from inhaled air and expel carbon dioxide in exhaled air.

I want to begin my presentation with medical terms related to the lung …….

II. Main part

1. 2. The next thing I want to talk about is the lungs structure……….

2. And now about how the lungs work……….

3. 4. Let me turn to the respiratory system ……….

4. I want to emphasize that you have to breathe because all of the cells in your body require oxygen….. .
