Human vs cetacean divers

Following a late dive in water, world brush aside endure arrant(a) pains upon reversive to the surface in any case quickly, and the resulting be spot may cause unconsciousness and death. Aches are so severe in near cases, commonly in the joints, that divers reverse everywhere in agony. Hence, the name, the bends. However, the more common name for this particularise is decompression sickness, signification that the sickness results from decreasing squelch. Divers experience decreasing obligate upon hike to the surface of the water. This is expected because pressure gradually increases with increase enlightenment of the water. Increases in pressure with reconditeness 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 quartet 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 gase s such(prenominal) 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 short letter into body tissues as bubbles. This process is similar to the protrudeance 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 d eath. However, some mammals do not experienc! e decompression sickness. These are the whales, porpoises, and dolphins, known conjointly as cetaceans. Cetaceans do not experience complications during dives as human being do, crimson though nitrogen dissolves in the blood of cetaceans to the depth of cc feet. Beyond that level, cetacean...
