The Respiratory System
The respiratory system brings oxygen into the body and removes carbon dioxide. This process is called breathing. It consists of inspiration and expiration. The organs of this system are the nose, pharynx, larynx, trachea and lungs. When you breathe, air travels through your nose, down the trachea, and into bronchi. These bronchi branch into smaller passages called bronchioles and finally into small sacs called alveoli.
The lungs are the most important organs of the respiratory system. There are two lungs in the body. The right lung has three lobes and the left lung has only two lobes. The lungs are separated by the mediastinum and covered by the pleura. They have bases, apexes, borders and surfaces. The average vital capacity is about 3-4 liters.
During inspiration, the alveoli in the lungs are filled with air. It is here that oxygen is exchanged for carbon dioxide. Blood cells absorb oxygen from the capillaries in the alveoli, as carbon dioxide, a waste product, is released back into the lungs from the veins. During expiration, the carbon dioxide is expelled from the body. Oxygen-rich blood then travels to the heart so it can be pumped back to the body where it is needed.

7. Put the sentences into the logical order
When you breathe, the air:
- travels down the throat through the larynx and trachea.
- one bronchus leads to the right lung and one to the left lung
- bronchioles end in tiny air sacs called alveoli
- goes into the lungs through tubes called bronchi
- in the lungs, the bronchi divide into smaller bronchi
- enters the body through the nose or the mouth
- and then into even smaller tubes called bronchioles
