The lung expands when it gets full of air , so the chest needs to do the same ,because if it didn't the lungs wouldn't fit in there when they get full , and that would be a terrible mistake of our body.
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, your diaphragm contracts and moves downward, expanding the chest cavity and drawing air into the lungs. The oxygen in the air is then exchanged with carbon dioxide in the blood. When you exhale, the diaphragm relaxes and moves upward, compressing the chest cavity and pushing air out of the lungs.
You can not know the position of diaphragm, when you inhale or exhale. The position of the diaphragm changes automatically.
The organ that expands to inhale and contracts to exhale is the diaphragm. When you inhale, the diaphragm moves downward, increasing the thoracic cavity's volume and allowing air to flow into the lungs. During exhalation, the diaphragm relaxes and moves upward, decreasing the thoracic cavity's volume and pushing air out of the lungs. This rhythmic movement is essential for breathing.
you inhale when your diaphragm contracts.
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.
the diaphragm. It is right above the heart and lungs, and expands and contracts when you breathe in and out. You can almost feel it move down a little, when you release air.
When the Diaphragm contracts, it is pulled down, and is pulled back up when it relaxes.Also, when you inhale, it contracts. When you exhale, it relaxes.
inhale
When you inhale, the diaphragm contracts and moves downward, while the rib cage expands, increasing the size of the chest cavity and allowing air to flow into the lungs. Conversely, when you exhale, the diaphragm relaxes and moves upward, and the rib cage contracts, decreasing the size of the chest cavity and pushing air out of the lungs. This change in chest space is essential for the breathing process.
Your diaphragm IS muscle. When we inhale, it is pushed down. When we exhale, it is pulled up.
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.
