Ribs: The ribs protect the lungs and expand as you inhale to facilitate space for the lungs to expand like the diaphragm. The ribs then contract expelling the air in the lungs.
The ribs enclose the thoracic cavity providing bony protection for the vital organs of the thorax's heart and lungs.
The diaphragm aids respiration by contracting (when we inhale) and relaxing (when we exhale). In doing so, this flat sheet of muscle increases / decreases the thoracic pressure to force air in or out of the lungs through a pressure gradient.
The ribs serve mainly to protect the thoracic organs, namely the lungs and heart. However, in between the ribs are muscles, which too contract or relax we we breathe in or out.
Well, as the diaphragm muscle is attached to the base of the ribs - especially during 'forced' exhalation - the diaphragm muscle uses the ribs as a bridge in forcing the air quickly from the body, when necessary.
During inhalation, the intercostal muscles that attach between ribs - from rib to rib - allow that the rib cage expands, which assits the lungs to more efficiently do their job of taking air in.
Of course, a major function of the ribs is to protect vital internal organs - such as heart and lungs from outside forces.
They provide a rigid cage for the action of the diaphragm to allow the lungs to expand. Without ribs, your chest would simply "suck in" whenever the diaphragm moved down, and you would be unable to breathe. This is why a "sucking chest wound" is so dangerous.... it's allowing outside air to surround your lungs, instead of having your lungs fill with air.
The Ribs primary function is to protect the thoracic viscera, or the heart and lungs. The pelvis' main function is to protect the pelvic viscera
Ribs move with the diaphragm to assist in breathing. While they are fairly rigid, just look at how your chest expands and contracts while breathing. If they were immovable, there would be no movement.
Position of; Intercostals.. In-between the ribs, running obliquely downwards Diaphragm.. Mid chest separating the thoratic and abdominal cavities. Action; ..Keeps us breathing when working with the ribs, sternum and lungs. ..expands and retracts with breathing
True ribs protect the heart, lungs and the diaphragm.
Your diaphragm lowers and your ribs expand outwards
Ribs are for protection i think and diaphragm is the muscle controlling inhaling and exhaling. Also: the rib muscles can help the breathing process, which is useful when the diaphragm is weak, constricted, or to get an extra-big breath. Breathing from the diaphragm makes the belly move in and out as the lungs extend downwards. Breathing from the rib muscles makes the chest expand and rise.
The intercostal muscles. Intercostal means "between ribs".
the diaphragm, chest muscles, ribs and the sternum.
The diaphragm goes down, pulling air into the lungs. Your ribs expand, helping your lungs to expand also.
Diaphragm
Lungs do not contain muscle tissue. air enters your lungs when the muscular diaphragm contracts, pulling your ribs up and out. The diaphragm relaxes when you exhale.
the name of the muscle that is attached to your ribs is called a Diaphragm,it helps your lungs to breathe.
