The Lungs


The Thorax

  • The thorax is the top part of your body.
  • It`s separated from the lower part of the body by the diaphragm.
  • The lungs are like big sponges and are protected by the ribcage. They`re surrounded by the pleural membranes.

The Thorax

  • The air that you breathe in goes through the trachea. This splits into two tubes called bronchi (each one is a bronchus), one going to each lung.
  • The bronchi split into progressively smaller tubes called bronchioles.
  • The bronchioles finally end at small alveoli where the gas exchange takes place.
