Can Humans Breathe Underwater Without Equipment?
Understanding Human Ability to Breathe Underwater
Frequently Asked Questions
No, humans cannot breathe underwater naturally as we do not have gills; we require equipment like scuba gear to provide oxygen.
Humans have lungs that extract oxygen from the air, while fish have gills that can extract dissolved oxygen from water.
