Hemorrhage or loss of large amount of blood occurs when there is a rupture in one or more blood vessel. Generally, small cuts, only capillaries are injured. Deeper wounds as in lacerations results in injury of veins and arteries. Bleeding which is severing enough to endanger life seldom occurs except when arteries or veins are cut or damaged.
The averaged adult body contains about 8 quarts of blood. A loss of one pint usually does not have harmful effects. But loss of two pints usually cause shock; and shock increases as the amount of blood loss increases. If half of the blood of the body is lost, death will result. The blood from ruptured capillary is usually brick-red in color, in ruptured capillary, the blood oozes out slowly. Blood coming from the veins is dark red in color. If a vein is cut or served the blood escapes in a steady even flow. An artery on the other hand near the surface, if cut gives out blood in spurts and is synchronized by the beating of the heart, a deeply buried artery that is cut will show a seemingly steady stream
Researchers have warned computers on the lap may affect fertility. They have found that the potential risk comes from the heat generated by the laptop and the proximity of the thighs when balancing the computer on the lap. This heat is transferred to the scrotum, where the temperature can rise several degrees, putting users within the danger zone for testicular dysfunction. Radiation from using laptop computers are also linked to the risk but is yet to be confirmed. Recent laptop models are manufactured in such a way that it deliberately emminates heat, to keeping computer’s interior cool. This heat is harmless when placed on a stable, flat surface yet quite harmful when placed over your sensitive region. The findings recommended that the young men should use desk or tables, instead of their own laps. Having hot lap dances, on the other hand, has no effect on fertility.
