Your two lungs are the same size
Your right lung is bigger because your heart takes up a lot of space on your left side. Both are divided into sections called lobes, and your right lung has three of these, while your left has two. Together, they weigh less than 3 pounds.
How many gallons of air do you breathe in each day?
That air puts much-needed oxygen into your bloodstream. If you stop breathing for longer than 4 minutes, it can permanently damage your organs.
As you age, your lungs hold less air.
Your lungs are at their peak when you’re in your 20s to mid 30s. After that, your diaphragm gets weaker and your lung tissue can’t stretch as well.
