Air Entering Our Body!

• When air enters our body, it goes down our
  windpipe. There are two branching tunnels, each
  of them lead to one of the two lungs. These
  tunnels are called bronchial tubes.

Bronchial Tubes!

• Bronchial tubes look like upside down trees. This
  also gives the bronchial tubes another name,
  called bronchial trees.
• The trachea is the trunk of the bronchial
  tree. The main branches are bronchial tubes,
  while the smaller branches, or twigs, are called
  bronchioles. The smallest bronchioles end inside
  our lungs.

Inside and Outside Our Lungs!

• At the end of our bronchial tube is a spongy
  lung tissue thats made of many sacs that are
  filled with air. The walls of these sacs are
  really thin. These sacs are called alveoli. The
  alveoli puts oxygen into the blood and removes
  carbon dioxide.
• Our lungs are located in the thorax, which is
  made of thick bands of muscles, or ribs.
