Mammals that live in the sea are different from us much deeper they reach. They even spend their lives at these depths.

Now they How is it not affected by water pressure?

Pressure is actually a big problem for marine mammals.

But their body systems are adapted to survive in the depths of the seas. with a large number of adjustments is equipped. For example, the lungs of these creatures are fully compressible.

In other words, the gases in the lungs of marine mammals are blood circulation and muscles can be sent. This conduction allows these gases to dissolve under pressure.

In addition, their lungs contain oxygen, a type of protein that stores oxygen in the muscles. myoglobin and hemoglobin They have adapted to preserve it.

The advantages of the lung structure of marine mammals are not limited to this.

This adaptation of the lungs also includes changes in the alveoli. gas exchange and nitrogen entering the bloodstream obstacles. When dissolved gases come out of solution as bubbles in the bloodstream, various twists occur.

This can be very harmful or even fatal for them. However, almost all marine mammals are aquatic by nature. slowly rise They have learned and thus manage to get rid of the pressure.

In addition, although marine mammals may have air in their ear canals or sinuses in their main cavities, the tissues lining these cavities are generally quite flexible and can expand easily. As this They can expel air and prevent pressure differences.
