It's interesting to know how our body reacts after our heart stops beating and normal bodily functions cease. Within as little as 24 to 48 hours after death, your internal organs will begin to decompose.
Decomposition after death, also known as autolysis takes place. Gases like oxygen, carbon dioxide, and other waste material can’t escape from the body and an acidic environment is created. The cell membranes begin to rupture because it is filled with enzymes, and your body begins to eat itself from inside out.
After that, the body gets doubled in size and gives out a strong odor due to decomposition. Insects that may be present, start to feed on the body. Slowly the organs, muscles, and tissues liquefy, and eventually, a skeleton remains.
