How can we take better<br />

Q<br />

Lungs are an amazing<br />

organ. Can you share with<br />

our readers some extraordinary<br />

facts about lungs?<br />

You have two lungs that are<br />

not the identical size—the lung<br />

on the left side is smaller than<br />

the right—to make room for<br />

the heart. Lungs consist of 300<br />

million capillaries (tiny blood<br />

vessels)—if they were laid out<br />

they would span 1,500 miles.<br />

This is where oxygen enters<br />

the blood and carbon dioxide<br />

is taken out. There are several<br />

tubes that unite your mouth to<br />

the insides of your lungs. Your<br />

trachea (or wind pipe) is the<br />

large tube you can sense in your<br />

gullet. This divides into core<br />

stem bronchi, which then split<br />

many further times into minute<br />

tubes called bronchioles. There<br />

are about 30,000 bronchioles<br />

in our lungs! At the end of all<br />

of these tiny tubes are small<br />

sacks called alveoli. These get<br />

larger and smaller with every<br />

breath, and hold lots of blood<br />

vessels which is where oxygen<br />

enters the blood and ravage (like<br />

carbon dioxide) leaves the blood.<br />
