Your Lungs Can Float — Even After You Die
Healthy lungs contain millions of tiny air sacs called alveoli. Even after exhaling, your lungs still hold a significant amount of residual air.
Because of this trapped air:
- Healthy lungs can actually float in water.
- Forensic pathologists sometimes use this fact during autopsies in specific investigations.
What’s surprising is that lungs are not solid organs like the liver or heart — they’re spongy and air-filled, which dramatically affects their density.
