How do fish breathe underwater?
Facts:
1. Fish breathe using their gills. They don’t have lungs like us they have gills instead.
2. Gases like oxygen and carbon dioxide can be dissolved in water. (Like the carbon dioxide bubbles in fizzy drink)
3. A fish’s gills are full of blood vessels that absorb the tiny particles of gas.
4. The fish sucks the water in through its mouth and squirts it out through its gills and that’s when the gills take the oxygen from the water into the blood vessels.
5. A fish’s gills aren’t able to take oxygen from air like us so they can’t breathe out of water.
Did You Know?
1. You don’t have gills - you have lungs instead.
2. Your lungs are full of lots of small blood vessels that small particles of gases to be exchanged in a gas mixture.
3. Your lungs aren’t able to collect oxygen from water so you can’t breath underwater.
4. Almost every living creature needs oxygen to survive (there are some bacteria that don’t)
5. Most fish don't sleep. Some rest by just floating in the water, but some have to keep moving to keep the water moving over their gills so they can get air.
6. Fish don't have eyelids so they can't close their eyes.
