Learning objective: To be able to identify what happens within the lungs and thoratic chamber when we breath in and out
- We have learned in the past sessions what happens inside the lungs when we breath and where the oxygen goes, In this lesson I want you to have a go at understanding how the lungs breath and what happens to the muscles around them.
- You have two sets of muscles that are attached to the rib cage and one muscle under the ribs. The one under the ribs is called the diaphragm and the two sets of muscles are called the intercostal muscles. We have both INTERIOR and EXTERIOR intercostal muscles
