Lungs

Description:

These big organs of the human body are the main part of the respiratory system. The lungs are responsible for absorbing oxygen we breathe to travel by our blood through veins and arteries. Each lung is attached to the other by the trachea and the branches you can see are called bronchi. At the end of each bronchus are the bronchioles, ending in a gland called alveoli. In the alveoli, oxygen is passing from the air to the blood and the passage of carbon dioxide from the blood to the air. To protect this set of organs, the human body has the rib cage or chest, which are the set of ribs joined together by the vertebral column (in the back) and sternum (for the front). The lung is the human body’s largest organ. The right lung is larger than the left, due to the space occupied by the heart.
