Human vs cetacean divers

Following a late dive in water, creation brush aside examine heartrending pains upon return to the surface in any case quickly, and the resulting be lesion may cause unconsciousness and death. Aches are so severe in near cases, commonly in the joints, that divers turn everywhere in agony. Hence, the name, the bends. However, the more common name for this shape is decompression sickness, signification that the sickness results from decreasing ram. Divers experience decreasing compress upon hike to the surface of the water. This is expected because pressure gradually increases with increase profoundness of the water. Increases in pressure with foresight are a result of increasing weight of the water. For example, at 150 feet, because of this weight, pressures on all surfaces of the body are quadruple and one-half times greater than they are at the surface. At this depth, pressure on the divers chest cavity, lungs, and air inwardly the lungs causes gases such as nitrogen in that air to dissolve in the parenthood of lung tissue. Dissolved nitrogen at high pressure and deep water causes no problems as long as the diver does not ascend. When the diver ascends, pressure decreases (decompression), and nitrogen is released from the course into body tissues as bubbles. This process is similar to the bug outance of bubbles in a washing soda after the cap is removed(p).

Bubbles appear because the pressure that kept them dissolved was removed with release of the cap. These nitrogen bubbles in tissues are the factor which cause damage, sickness, and death. However, some mammals do not experience decompression sickness. These! are the whales, porpoises, and dolphins, known jointly as cetaceans. Cetaceans do not experience complications during dives as military man do, crimson though nitrogen dissolves in the blood of cetaceans to the depth of cc feet. Beyond that level, cetacean...
