more oxygen
more carbon dioxide
more lactic acid
Suggest what happens to a performers' breathing rate during exercise.
Breathing rate increases
Breathing rate decreases
Breathing rate remains the same
Describe the Diaphragm.
a muscular sheet at the base of the chest cavity
the muscles between the ribs that raise and lower the ribs
the muscles in the abdominals that support breathing
the muscles in the lungs that allow for exhalation
Describe the intercostal muscles.

Suggest two functions of the Intercostal muscles during breathing.
contract to expand the chest cavity by moving the ribs up and out during inspiration.
relax to reduce the chest cavity by allowing the ribs to move downwards and inwards during expiration.
Increases pressure of the lungs
Decreases pressure in the lungs
Describe the function of the intercostal muscles in normal breathing.
