Lung Physiology

Lung AnatomySometimes problems in the chest area might not be heart-related, but have more to do with issues related to the lungs. Just as you can get heart disease or heart disorders, you can also get lung disease or lung disorders.

As you breathe, you take in oxygen which allows your pulmonary system to function. With every breath you take, however, your lungs are exposed to airborne bacteria which could contain viruses and allergens that potentially cause lung disorders. Some of these allergens may only be minor irritants causing temporary respiratory problems which could be treated by a specialised respiratory medicine physician, however more severe irritants or disease can cause severe lung damage that may require surgery by a cardiothoracic surgeon.

About your Lungs

The lungs are the organs responsible for adding oxygen to the blood after removing the body’s carbon dioxide. The lungs lie on either side of the heart. Your lungs, which take up most of the space in your chest inside your rib cage, are divided into sections called lobes – three in the right lung and two in the left. Each lobe is made up of spongy tissue containing many small breathing passages, called bronchial tubes. Air flows into and out of the lungs through these tubes.
