  4. 4. Unit 3(b): Human body. 1.         New words. Vocal cords- cuerdas vocales. It reaches- alcanza. Network- red. Branches- ramas. Exchanged- intercambio. Increase- aumentar. Relaxes- relajar. Keep- mantener.
  5. 5. Unit 3(b): Human body. 2. Breathing and parts of the respiratory system. -By breathing we obtain the oxygen our cells need to work and excrete the carbon dioxide our cells produce as a residue.
  6. 6. Unit 3(b): Human body. PARTS OF THE RESPIRATORY SYSTEM.  -The airways- the nassal passages, the pharynx, the larynx, the trachea, the bronchi, the bronchioles and the alveoli.   The lungs- are separated from the abdomen by the diaphragm.
  7. 7. Unit 3(b): Human body. 3-The phases of breathing. There are two phases when you are breathing: 3.1- Inhalation. 3.2- Exhalation.
  8. 8. Unit 3(b): Human body. 3.1 Inhalation.  The air enters into the nasal passages and continues down the alveoli.  The diaphragm contracts.  The volume of lungs increases.  The oxygen passes into the blood, which distributes around the body.  The carbon dioxide in the blood passes to the alveoli.
  9. 9. Unit 3(b): Human body. 3.2. Exhalation. The diaphragm relaxes and the lungs get smaller. The air full of carbon dioxide is expelled through the airways.
