What happens to Our Body after we Die? | #aumsum #kids #science #education #children

Doctors declare a person dead when his heartbeat and respiration stops, and his brain is dead.

Once a person is dead, all the muscles in his body relax. The jaw falls open, eyelids lose their tension and relax, etc. This state is known as primary flaccidity.

Also, the body begins to slowly lose heat and the body temperature begins to drop until it matches with the surrounding. This is known as a death chill.

As the heart has stopped pumping, within minutes, the blood begins to settle in the lower parts of the body, making those parts of the skin appear bluish purple or purplish red. This is called livor mortis.

Within 3 to 6 hours, the muscles start to contract. This is known as rigor mortis.

It can last from 24 hours up to 84 hours, after which the muscles again begin to relax. This state is known as secondary flaccidity.

Now, if the body is burnt, it gets converted to ashes. Otherwise, the body starts decomposing.

Since the blood circulation and respiration has stopped, the body can neither receive oxygen nor remove toxic by-products like carbon dioxide. Hence, these toxic by-products produce an acidic environment inside the cells, causing their enzymes to eat their own cells from inside out.

Moreover, we have different microorganisms in our gut, on our skin, etc. As there is no immune system anymore to control these microorganisms, they travel to different parts of the body and begin to breakdown the tissues and organs, releasing various gases. These gases attract insects like flies, maggots, etc. which also eat and breakdown the tissues.

Eventually, a time comes, when only the skeleton is left. However, over time the skeleton also decomposes.
