Describe the function of your diaphragm and explain how inhaling and exhaling occurs?
Breathing is done by your diaphragm. When you breathe in, your diaphragm tightens (contracts) and moves downward so your lungs can expand. When you breathe out (exhale) your diaphragm relaxes (expands) and moves up into your chest.
What two statements describe how the diaphragm works?
The diaphragm is a dome-shaped muscle that contracts and relaxes during breathing. When it contracts, it flattens out and pulls downwards, creating a vacuum that expands the chest cavity and draws air into the lungs. When the diaphragm relaxes, it moves back to its original dome shape, pushing air out of the lungs as the chest cavity decreases in size. This process of contracting and relaxing allows for inhalation and exhalation, enabling breathing to occur.
What part of the body helps us breathe in?

When nerve impulses pass to the diaphragm the diaphragm relaxes and exhalation occurs is this true or false?
False
What causes the diaphragm to return to its dome shaped position?

Muscle that contracts and relaxes to move gas into and out of the lungs?
Diaphragm
What is the muscle that contracts and relaxes so that you can breath is the?
