Q

What are the functions of the trachea?

A
  • the cartilage strengthens and supports
  • the ciliated epithelium traps mucus and dust (also happens in the lungs)

Q

What happens when the diaphragm moves down (breathing in)?

A

This increases the chest area for air to enter the lungs (caused by contraction of the diaphragm) then the intercostal muscles work together by contracting to pull the rib cage upwards

Q

What happens when the diaphragm relaxes?

A

The chest space decreases which forces air out of the lungs. Then the intercostal muscles work together to pull the rib cage downwards

22
