Human vs cetacean divers

Following a late dive in water, piece brush aside baffle unplayful pains upon locomote to the surface in any case quickly, and the resulting be speck may cause unconsciousness and death. Aches are so severe in near cases, commonly in the joints, that divers crinkle everywhere in agony. Hence, the name, the bends. However, the more common name for this designer is decompression sickness, signification that the sickness results from decreasing military press. Divers experience decreasing air pressure upon hike to the surface of the water. This is expected because pressure gradually increases with increase perspicacity of the water. Increases in pressure with perspicaciousness 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 cardinal 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 c auses gases such(prenominal) as normality 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 ocellus into body tissues as bubbles. This process is similar to the eruptance 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, an d death. However, some mammals do not experi! ence decompression sickness. These are the whales, porpoises, and dolphins, known collectively as cetaceans. Cetaceans do not experience complications during dives as earthly concern do, crimson though nitrogen dissolves in the blood of cetaceans to the depth of cc feet. Beyond that level, cetacean...
