The human body is about 60% water but the water is not quite as salty as ocean water. Would be the effect of drinking seawater? Both state the term and explain the condition.
Drinking seawater would increase the salinity of blood. This would cause cells to be hypertonic and shrink. This would serve to draw water out of the cells, which may ultimately crenate and die. The body would be full of water, but the person would be thirstier than ever. The results of dehydration would appear faster by drinking seawater.
