What happens to the size of the chest cavity as you inhale?
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.
Do you in hale or exhale when the volume of the chest cavity increases?
The air pressure in your chest cavity increases when you are exhaling. For air to leave your lungs, it must be at a higher pressure than the air outside. Your diaphragm pushes up against your chest cavity causing the space in your lungs to get smaller. If the volume decreases, the pressure has to rise. Don't believe me? start exhaling, then close your mouth. Your cheeks will puff out because the pressure inside is greater than the pressure outside.
When your inhale what contracts?
When you inhale, the diaphragm, a dome-shaped muscle located at the base of the chest cavity, contracts and moves downward. This contraction increases the volume of the thoracic cavity, causing a decrease in pressure and allowing air to flow into the lungs. Additionally, the intercostal muscles between the ribs also contract, further expanding the chest cavity.
What happens to your chest when you inhale?
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.
Which structure contributes to pressure changes in the chest cavity?
when you inhale..(take in oxygen)..the air fills up the lungs, the ribcage expands and the muscle sheet called the diaphragm pushes downward and flattens as you inhale ..whn you ehale the muscle returns back to domed-shape

What happens to the volume of your chest cavity when you enhale?
When you inhale, the volume of your chest cavity increases. This expansion lowers the pressure inside your chest relative to the outside air, allowing air to rush in and fill your lungs. This process is driven by the contraction of the diaphragm and the expansion of the ribcage.

What happens to the volume of his chest cavity when he inhales?
The volume of the chest cavity is reduced on exhalation. Imagine your lungs are balloons. Imagine the volume of a balloon full of air, compared to when it is not inflated. The balloon has a greater volume when it is inflated than when it is deflated - just like the lungs do!
What happens to lungs when you inhale?
what happens when you inhale is that air goes into your lungs and your lungs get bigger ...Actually, your diaphragm moves to expand the volume of your thoracic cavity, which pulls a partial vacuum on your lungs, causing them to expand FIRST...and THEN the partial vacuum created by your expanded lungs causes air to move into them. When you breath out, it causes the reverse to occur.
What parts of the respiratory system when you inhale?
answer: diaphragm at the bottom of the chest cavity is a muscle called the diaphragm. when the diapragm contracts, the chest cavity becomes larger.

What happens to the diphgram when you inhale?
The diaphragm is a convex shaped muscle (convex side within the chest cavity).When the diaphragm muscle contracts it flattens out and drops down out of the chest cavity making more room and creating a vacuum -- air then rushes into the lungs.When the diaphragm relaxes it moves back up into the chest cavity and expels the air on the lungs. During inhalation, the increased volume of the lungs causes the ribcage to expand. Inhalation - Diaphragm CONTRACTS and moves DOWN (to allow more space in the chest cavity for lungs to expand).Exhalation - Diaphragm RELAXES and moves UP (to force air out of the lungs).
