15 Body Parts You Can Actually Live Without

9. Lung

Lungs

We typically have two lungs. At least one lung is necessary to add oxygen to the blood. If all or part of a lung is removed, the remaining lung may expand to take on some of the work of the missing lung. Of course you’ll just have a harder time breathing in many instances.

8. Sinuses

Sinuses are another mysterious body part of the human body. What we do know about them is that they are abundant air-filled spaces in the nasal cavity that can become easily infected. They are especially irritating to allergy sufferers, and something we could certainly live without.
