how many lungs in human body

Humans normally have two lungs: a right lung and a left lung.

Quick Scoop

  • The human body has 2 lungs, one on each side of the chest.
  • The right lung is usually larger and has three lobes, while the left lung is slightly smaller and has two lobes to make room for the heart.
  • Most people live their whole lives with both lungs, but it is possible (though not ideal) to survive with just one lung after surgery or illness.

For a simple mental picture: think of your lungs as a pair of soft, spongy air-bags in your chest that work together to bring oxygen in and remove carbon dioxide from your blood every time you breathe.
