     • The bronchi are the two large tubes that carry air from your windpipe to your lungs. You have a left and right main bronchus in each lung. After the main bronchi, these tubes branch out into segments that look like tree branches. Many respiratory conditions, such as asthma or bronchitis, can affect your bronchi.

   How do bronchial tubes pass through the lungs?

   • As the bronchial tubes pass through your lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has about 600 million alveoli. The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from inhaled air passes into your blood.

   How does the respiratory system work?

   • The main job of your respiratory system is to bring oxygen into your lungs and move carbon dioxide out of them (gas exchange). It works closely with your circulatory system — your heart, blood and blood vessels — to do this. Think of the oxygen in the air as passengers on millions of planes flying into your lungs every time you breathe in.
