Lung & Respiratory Symptoms

Common lung and respiratory symptoms during disease states, illnesses, or disorders are difficulty and/or discomfort breathing, typically due to an impairment in the function of the lung.

However, less obvious symptoms and certainly more serious complications may arise as a result of the various lung and respiratory conditions.

The respiratory system stretches from the mouth, through the pharynx and larynx, through the trachea and bronchi, into the lungs. Its chief role is in the exchange of oxygen into the blood within the lungs and the exchange of carbon dioxide and other waste gases out of the blood.

Very small air sacs in the lung, alveoli, are in very close proximity to the smallest blood vessels in the body, capillaries. Together, millions of these elements together in the lung allow for respiration.

Respiration is controlled by primitive centers of the brain. It is automatically regulated based on sensors in the brain and in some blood vessels, which control the rate of breathing depending on the oxygenation level of the blood.

Any condition which prevents the body from bringing fresh air into the lungs, or removing stale air from the lungs, will result in complications. Commonly these conditions involve infection and/or obstruction of the airways or the lung tissue itself.

Different lung and respiratory symptoms and disorders are covered below where more specific symptoms can be addressed.
