The movement of the diaphragm affects the size of the chest cavity by when you inhale the chest cavity enlarges, but when you exhale the chest cavity becomes smaller.
When you inhale, the volume of your chest cavity increases. This expansion is caused by the contraction of the diaphragm and intercostal muscles, allowing more space for the lungs to expand and fill with air.
answer: diaphragm at the bottom of the chest cavity is a muscle called the diaphragm. when the diapragm contracts, the chest cavity becomes larger.
When you inhale, the chest cavity expands. Seventh grade life science, baby.When you breathe in, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
When you inhale, the diaphragm contracts and moves downward. This movement creates more space in the chest cavity, allowing the lungs to expand and fill with air.

The diaphragm relaxes and reduces the space in the chest cavity.
When you inhale, the diaphragm contracts and moves downward. This movement creates more space in the chest cavity, allowing the lungs to expand and fill with air.
When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs.
When you inhale, the diaphragm muscle contracts and moves downward, and the rib cage expands as the intercostal muscles between the ribs contract. This creates more space in the chest cavity, allowing the lungs to expand and fill with air.
