LUNGS-

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi

What are the 4 main functions of the lungs?

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

Where are the lungs found

 The lungs are found in the chest on the right and left side. At the front they extend from just above the collarbone (clavicle) at the top of the chest to about the sixth rib down.
The most common lung diseases include:
  • Asthma.
  • Collapse of part or all of the lung (pneumothorax or atelectasis)
  • Swelling and inflammation in the main passages (bronchial tubes) that carry air to the lungs (bronchitis)
  • COPD (chron

Lungs disease by smoking

Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis. Cigarette smoking causes most cases of lung cancer. If you have asthma, tobacco smoke can trigger an attack or make an attack worse. Smokers are 12 to 13 times more likely to die from COPD than nonsmokers.
