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 breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
The contraction of the intercostal muscles, (muscles in between the ribs), expands the thoracic cavity.
usually, it expands, but some people have reverse breathing, so it contracts.
when we inhale,we lift the ribs,and the diaphragm flattens ,expanding the capacity of lungs to withhold air,thereby the chest cavity becomes larger
When you inhale the volume increases, because the chest cavity expands to hold your breath.It increases.
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.
Lots of push ups can give you finely tuned chest muscles
you get cancer
I can only tell you about helium. If you inhale it, you will sound funny for a minute or so.

inhale
When you inhale your rib muscle and diaphram contract and expand the chest cavitie. When you exhale you rib muscle and diaphram relax, reducing the size of the chest cavitie.
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.
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.
Nothing happens to me.. Yet
