The human reflex is to breathe in air when the lungs need it. So the lungs dont burst from not getting air, the person instinctively opens their mouth for air and swallows all the water, which then fills their lungs with water. Once all these gasses have escaped from the body its average density is higher than water and so the body sinks. Interstingly dolphins are the only mammals that do not have the reflex memtntion above and so when they are trapped in a net under the water they hold their breath and suffocait themselves.
