Why can't we breathe in water like fish?

Hello lovely friends!
Every living thing needs oxygen to breathe. Human and animal plants need this gas. Oxygen is spread both in air, water and soil.
when breathing air to breathe means we are taking oxygen. But then we think why water which is also made up of oxygen why can't we breathe it?
Why only fish and creatures in water can take oxygen to breathe in water?
We must be able to find the answers to these questions so that when our children ask questions, we will be able to explain clearly.

The form of oxygen


When breathing we breathe air. This air contains oxygen. The oxygen we take is free and not bound by other elements. The lungs can directly utilize oxygen from the air after filtering through temperature and humidity adjustments.
The inner lining of our lungs is also designed for air, not water. That is why we cannot breathe in water.
We cannot take oxygen directly from the water. Water (H2O) comes from the chemical reaction of 2 hydrogen molecules and 1 oxygen molecule. In this form, oxygen is no longer useful for the lungs because the oxygen used to make water is bound to 2 hydrogen molecules
Oxygen content in air is more than water so extracting oxygen in water is not easy. Need a special tool that can make the oxygen content in water used for breathing.
Of course humans are different from fish. Fish that can breathe in water using a gill breathing device. With the help of gills, fish absorb and separate water-soluble Oxigen.
Besides the different respiratory organs, another reason why gills work for fish is because fish are cold-blooded animals. Cold-blooded animals do not need a lot of oxygen, in contrast to mammals that are warm-blooded and need a lot of oxygen.
Warm-blooded animals need more oxygen. Like the whale will breathe air with the lungs like humans because it will be very difficult to absorb oxygen in large quantities using gills. So they will routinely come out to the surface to breathe air.
Thus my writing this time may be useful for us all.

Thank you for reading my post. I hope you enjoy it.

Dolphin looks nice and friendly! It’s useful to be able to breath like dolphins! But I don’t know how! LoL

We.must change our lung to absorb oxygen in the water..
