Why cant human dive us deep us other diving animals

A detailed Summary of Why cant human dive us deep us other diving animals

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 nitrogen to escape the body. Some animals goes down much deeper then we do, so how come they don't get the bends are die from the pressure?

Like some seals and whales that could go 10 times deeper then us and comes back to the surface 10 times faster. How come they don't suffer from this? Researchers had found that deep diving animals rely far less on air stored

When the seal ascend the lungs collapse rapidly, keeping large amounts of nitrogen from entering the blood. The collapse of the lungs halts the flow of all atmospheric gases form the lungs into the bloodstream. They also prevent the flow of oxygen into the blood. When this animal does deep dives, the muscles are working much harder than any other organ. It will carry their own supply of oxygen in the form of myoglobin. Deep diving animals' stores 47 percent of its overall body oxygen in its muscles, the rest is circulating through the blood and lungs.

Also diving animals have a special way of controlling their heartbeat. Not like us, where we can't control our heartbeat. On land seals has a heart beat of 107 beats per minute, but at sea, as it dives down to the deep

Some common words found in the essay are:
, beats minute, store oxygen, heart beat, lungs oxygen, dives deep, oxygen myoglobin, slow metabolic, seal dives, oxygen blood, 10 times,
