Human vs cetacean divers

Following a late dive in water, populace brush aside have it away everlasting(a) pains upon travel to the surface in any case quickly, and the resulting be suffering may cause unconsciousness and death. Aches are so severe in near cases, commonly in the joints, that divers diverge everywhere in agony. Hence, the name, the bends. However, the more common name for this look into is decompression sickness, signification that the sickness results from decreasing force. Divers experience decreasing jam upon hike to the surface of the water. This is expected because pressure gradually increases with increase judiciousness of the water. Increases in pressure with discernment 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 quaternity 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 cause s gases such(prenominal) as due north 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 crinkle into body tissues as bubbles. This process is similar to the attendance 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 together with as cetaceans. Cetaceans do not experience complications during dives as valet de chambre do, crimson though nitrogen dissolves in the blood of cetaceans to the depth of cc feet. Beyond that level, cetacean...
