The respiratory system is an amazing process by which the body takes air from the environment into the body to feed the blood and cells with oxygen, and then expels air containing carbon dioxide and toxins back out into the atmosphere. This process is called gaseous exchange. This takes place in the lungs. The complete process involves the nasal passages, the pharynx, larynx, trachea, bronchi, lungs and muscles; diaphragm, external and internal intercostals, transverse abdominal, scaleni and sternomastoids.
