When a diver dives deep for a period of time, breathing regular compressed air, a certain amount on nitrogen will be dissolved in the blood. If the diver comes back up to the reduced pressure of the surface too quickly, small bubbles of nitrogen will form in the blood stream. This is called "the bends" and requires the person to spend some time in a decompression chamber to gradually reduce the pressure and allow the …showed first 75 words of 502 total…

If the metabolic activity slows down, your body will function slower; this lets the seal dives deeper. In humans, kidneys can be hurt quickly if blood flow is reduced. But the diving animal is unaffected by this. Their ability to slow down the metabolic rate and storing myoglobin in their muscles let these divers dive deeper then us and not suffer from the bend.
