What is the purpose of the diaphragm?

To produce sound

To assist with breathing
To stabilize the heart

The correct answer is: To assist with breathing

The diaphragm is a crucial muscle in the respiratory system, primarily responsible for facilitating breathing. When the diaphragm contracts, it moves downward, creating a vacuum that draws air into the lungs. This action is essential for inhalation. Conversely, when the diaphragm relaxes, it moves back to its original position, helping to push air out of the lungs during exhalation. Its role as a primary muscle of respiration makes it vital for effective breathing and oxygen exchange in the body. Understanding the diaphragm's function is important for recognizing its impact on overall respiratory health, distinguishing its role from other bodily functions like sound production or digestion.
