Underwater breathing
Underwater breathing involves the use of specialized equipment, such as scuba gear, which supplies air from tanks holding compressed breathable gas (usually a mix of oxygen and nitrogen). This gear allows divers to breathe comfortably beneath the surface by providing a continuous flow of air, bypassing the need to surface for air. The diving apparatus manages pressure changes due to depth and ensures that the diver's inhaled air is safe and appropriately regulated. This technology enables humans to explore underwater environments safely for extended periods, making underwater breathing possible without the need for natural gills.
