Periosteum is a membrane that covers the outer surface of all bones, except at the joints of long bones. Endosteum lines the inner surface of all bones.
The process of breathing involves the exchange of gases, namely, oxygen and carbon dioxide that occurs between you, in particular, the cells of your body, and the outside environment, which is the air. This exchange happens in the lungs. In all, breathing has two components: Ventilation, or movement of oxygen into, and carbon dioxide, out of your lungs. Circulation, or transporting the oxygen taken into the body during ventilation to where it is needed in the body. In terms of how breathing can enhance your therapeutic back exercise program or your successful participation in a pro-active holistic therapy, it's the ventilation component that takes center stage.
Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose every time you breathe in. The oxygen then passes through the larynx (also known as your âvoice boxâ) and then through the trachea to the chest cavity.espiration is achieved through the mouth, nose, trachea, lungs, and diaphragm.
