Your right lung and left lung aren't the same size. 😂

You'd probably expect them to be almost identical, since they're both doing the same job.

But they're not.

Your right lung is slightly larger than your left lung.

And there's a very good reason for that.

Your heart sits slightly toward the left side of your chest, taking up some of the space where the left lung would otherwise be.

So your left lung has a little less room to work with.

It even has a small indentation called the cardiac notch, which makes space for the heart.

And there's another cool difference:

The right lung normally has three lobes, while the left lung has two lobes.

So your lungs aren't really a matching pair.

They're more like siblings who were given the same job but ended up with slightly different designs. 😭😂

And despite the difference in size, both lungs work together to bring oxygen into your body and remove carbon dioxide when you breathe.

So every time you take a breath, two slightly different organs are working together without you even thinking about it.

Quick fact: The right lung is generally larger and has three lobes, while the left lung has two lobes and a cardiac notch that accommodates the heart.
