Mouth and Nose
Where oxygen enters the respiratory system
cleans the air of dust warms the air if it is
too cool moistens the air if it is
dry
Trachea

Produces mucus which traps particles
Lungs Deoxygenated blood
is pumped into the pulmonary artery.
oxygen diffuses into blood and is exchanged with carbon dioxide.
Diaphragm
separates thoracic cavity from abdominal cavity
Expansion and contraction causes respiration
Dysfunctions
