The two main branches of the trachea, with cilia and cartilage rings, they go into the lungs and further divide into the bronchioles...........................................

A large, dome-shaped muscular membrane that contracts, increases the volume of the thorax and lowers air pressure in the lungs causing inspiration; ........................................

A disease that progressively destroys the walls of the alveoli making breathing difficult; .................................

The abdominal muscles contract causing reduced thorax volume. Does it happen during expiration or inhalation? .................................

Muscles found between the ribs. They are can move the rib cage up or down. .......................................
