It allows your rib cage to move when the lungs inhale and exhale
Your diaphragm expands, your rib cage goes up, and your lungs also expand. I learned this in science.
in out in out
it expands as we inhale and contrasts as we exhale...this allows our lungs to fill up with air without pushing on out rib cage the rib cage moves up and out when inhaling and moves down and in when exhaling.
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.
yes it can hurt. One day i was jumping on a trampoline ans the next day my right rib cage was hurting. It was very hard to inhale and exhale. It helps if you put an icepack on it.
These are the muscles that move the rib cage and they work together:Diaphragm (Prime mover of inhalation). If you need to breathe deeper you will use these:Scalenes (Elevate rib cage, assist in inhalation)Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)Pectoralis minor (Elevate Rib Cage, assist in inhalation)External Intercostals (Elevate rib cage, assist in inhalation)Internal Intercostals (Depress, assist in exhalation)The diaphragm is under both voluntary control (holding your breath) and involuntary control (sleeping, reading)
It is called the Diaphragm, which is under the lungs and rib cage. ---- The Diaphragm is what moves the rib cage up and down when you breath in and out.
it is not possible to cunstruct a rib cage again.
You can break your rib cage a number of ways but overall from a blunt blow to the rib cage
