* Lungs and Oxygen: Humans have lungs, which are specialized organs that take in oxygen from the air we breathe. Our lungs are filled with tiny air sacs called alveoli, where oxygen passes into our bloodstream and carbon dioxide exits.
* Water and Oxygen: Water contains far less dissolved oxygen than air. Even if we could somehow get water into our lungs, the amount of oxygen present wouldn't be sufficient to sustain our bodies.
* Gills: Fish, on the other hand, have gills. Gills are specialized organs that extract oxygen from the water. They have a large surface area covered in thin, delicate filaments that maximize the absorption of dissolved oxygen.
Why We Drown: When humans inhale water, it fills our lungs and prevents them from taking in oxygen. This causes our bodies to be deprived of oxygen, leading to suffocation and ultimately death.
Important Note: It's crucial to remember that water safety is vital. Never swim alone, always be aware of your limitations, and never attempt to hold your breath for extended periods.
