5 Lung Facts You Might Not Know

1. Your left lung is smaller than your right one.
Can you guess why?

ETA this answer: While your heart sits more or less in the center of your chest cavity, the larger part bulges out to the left, leaving less space for that lung.

2. The word *lung* probably comes from *lunge,* the Old English word for *light.*
As related to weight, not illumination, and explaining the following:

3. Your lungs are your only organs that can float on water.

4. You have 1500 miles of airways.
No wonder asthma gets so bad. That’s 1500 miles of potential inflammation.

5. You take approximately 22,000 breaths every 24 hours.

    I did not know these things. Number 4 is fascinating!

    I am going to guess on number one and this is totally without cheating on Google, lol.

    Is it because when you are developing in the womb, your heart and the left side of your body where you heart lives is built first – the reason why people who have heart attacks often feel pain or numbness in their left arm before or during the actual attack? Maybe because it is created first, but in a small space it stays proportionally smaller but grows at the same rate?

    Yes, teacher, I am BSing. lol

    Great blog btw.

    Big AG, total surface area of the lungs and alveoli is about equal to the surface area of a tennis court. Crazy, huh?

    GeorgeandWheezie, love the name first of all. Thanks for a chuckle this afternoon. And good guess, but um–no. (You’re close, though!) That’s an interesting theory.

    It might be gross, but one of the ways a vet can tell if a calf (or any other animal for that matter) was still born or not is by putting their lungs in water. If they sink the animal never took its first breath.

    I did like #4 though, I didn’ t know that!

  5. Amy says:

    That is one fascinating lung fact and not gross at all. (to me, at least) Thanks!

    hours these days, but I by no means found any attention-grabbing article

    internet will likely be much more helpful than ever before.

  28. Hands down, Apple’s app store wins by a mile. It’s a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.
