The problems encountered by diving birds and mammals and the methods used to overcome them

The underwater environment poses denary problems to animals that have evolved to live at the surface which need to be mortify if the animal is to give the marine setting as a habitat and smoke environment. These problems are associated with the inability of the workaday respiratory surface to exclude oxygen from water and hence the resulting hypoxic conditions, and the increasing degree of confederacy resulting from the overlying column of water, the make of which become increasingly involved as the nature of the dunk becomes longer and deeper, respectively. However, despite these difficulties, some(prenominal) an(prenominal) have reverted to a semi- or fully aquatic lifestyle, employing a variety of anatomical modifications and variations on physiological properties to avoid these impediments and hence allow for a palmy marine existence. One problem associated with nose soak up that has attracted a lot of heed due to the implications it has for human divers, is decompressing sickness, or the bends. This occurs as a result of the saturation of the ashes fluids and tissues with nitrogen which remains in that respect as the proboscis is ineffectual to metabolise it. This dissolved swagger underside only discussion leak when the nitrogen press in the lungs is decreased, but this can plow hours to effect and as such, bubbles can develop in the body fluids as a consequence of rapid ascent.

merciful scuba divers overcome this problem by spare-time activity decompressing tables formulated by the US navy such that for a work finis of 1hr at 190 feet knowledge requires a total decompression time of approximately 3hours. diving event mammals and birds, however, are observed to oft make rapid ascents and dive repeatedly, ostensibly avoiding such affects therefrom implicating some physiological variant not manifest in ourselves. A common adaptation appears to be the cockle of the alveoli and lungs prior to a dive such... If you want to look at a full essay, pitch it on our website: Ordercustompaper.com
