Did You Know?

* The main cause of death in cases of cancer were LUNG CANCER (lung cancer contribute to 32% of death in men and 25% in women with cancer)
* 90% of lung cancer sufferers are active smokers or former smokers
* Smoking a pack a day increases the risk of lung cancer 10 x fold
* Smoking two packs a day increases the risk of cancer 5 x folding
* From 180 thousand people convicted of lung cancer every year, 86% will DIE within 5 years since terdiagnosa (this is new in the United States only).

To be able to understand cancer, it is important for us to understand how the structure of the lungs of humans (normal) and how it works.

The Anatomy Of The Human Lung

The lungs are sponge-shaped organ located in the chest. The right lung has three lobes, while the left lung has two lobes, as shown in the image below.



The left lung is smaller because the heart takes more space on the side of the body. The lungs bring air into and out of the body. They pick up oxygen and remove carbon dioxide gas (substance residues respiratory tract).

Lining around the lungs is called pleural, help protect your lungs and allows them to move during breathing. The stem of the throat (Thrace) brings air into the lungs. Thrace is divided into a tube called the bronchi, which then split again into smaller branches called bronkiol. At the end of this small branches are small sacs called the alveoli.

At the bottom of the lungs, the diaphragm is a muscle that separates the chest called of the belly (abdomen). When you breathe, the diaphragm moves up and down, forcing the air into and out of the lungs.
