What should we know about Pneumonia?
Starting from the trachea, the main branch goes out: right and left main stems (the main bronchi) supply the right and left lung lobes, respectively. Each lung is then divided into several pulmonary lobes. These are provided by increasingly fine-branched bronchi and bronchioles, which carry the air we breathe deep into the lungs to the alveoli (air sacs). Gas exchange takes place in these air-filled vesicles. The lungs make sure that oxygen is transferred from the air we breathe into the blood and that carbon dioxide is removed from the blood into the air we breathe out. The human lung has about 300 to 400 million alveoli.
