							We define BREATHINGas the expansion and contraction of the ribcage (chest) using the muscles located in between the ribs. The muscles consist of the meat eaten when people have ribs from pork or whatever animal. The diaphragmis another muscle which participates in this process. Diaphragam is a thin layer of muscle, separating the thoracic cavity from theabdominal cavity. When the diaphragm moves downwards it pulls air into the body as if it was the plunger of a syringe.Once air, containing the valuable oxygen (about 20%) is inside the lungs, the oxygen is transported, via bloodstream, to the cells all over the body, where respiration takes place.
Now,RESPIRATIONis the reaction that converts oxygen and glucose into carbon dioxide, water and releases ENERGY to be used elsewhere!68-2280_1.jpg
