When you breathe in, or inhale, 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 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.

When you inhale, your diaphragm and rib muscles contract, expanding your chest cavity and allowing air to be drawn into your lungs. This process brings oxygen into the body. When you exhale, your diaphragm and rib muscles relax, causing your chest cavity to decrease in size and push the air out of your lungs. This process expels carbon dioxide from the body.
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.

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.
The intercostal muscles are located between the ribs and help expand and contract the chest cavity during breathing. When you inhale, these muscles contract, lifting the ribcage and expanding the chest cavity, allowing air to enter the lungs. When you exhale, the intercostal muscles relax, allowing the ribcage to lower and the chest cavity to decrease in size, pushing air out of the lungs.
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.
