DeathDeath is the irreversible cessation of all biological functions that sustain an organism. For organisms with a brain, death can also be defined as the irreversible cessation of functioning of the whole brain, including the brainstem, and brain death is sometimes used as a legal definition of death. The remains of a former organism normally begin to decompose shortly after death. Death is an inevitable process that eventually occurs in all organisms. Some organisms, such as Turritopsis dohrnii, are biologically immortal.
DecompositionDecomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere. Bodies of living organisms begin to decompose shortly after death. Animals, such as worms, also help decompose the organic materials. Organisms that do this are known as decomposers or detritivores.
Ancient Egyptian religionAncient Egyptian religion was a complex system of polytheistic beliefs and rituals that formed an integral part of ancient Egyptian culture. It centered on the Egyptians' interactions with many deities believed to be present in, and in control of the world. About 1500 deities are known. Rituals such as prayer and offerings were provided to the gods to gain their favor. Formal religious practice centered on the pharaohs, the rulers of Egypt, believed to possess divine powers by virtue of their positions.
OsirisOsiris (oʊˈsaɪrᵻs, from Egyptian wsjr) is the god of fertility, agriculture, the afterlife, the dead, resurrection, life, and vegetation in ancient Egyptian religion. He was classically depicted as a green-skinned deity with a pharaoh's beard, partially mummy-wrapped at the legs, wearing a distinctive atef crown, and holding a symbolic crook and flail. He was one of the first to be associated with the mummy wrap. When his brother Set cut him up into pieces after killing him, Osiris' wife Isis found all the pieces and wrapped his body up, enabling him to return to life.
TutankhamunTutankhamun (ˌtuːtənkɑːˈmuːn ), Tutankhamon or Tutankhamen (ˌtuːtənˈkɑːmən,_-mɛn ; 1341 BC-1323 BC), also known as Tutankhaten, was the antepenultimate pharaoh of the Eighteenth Dynasty of ancient Egypt. His death marked the end of the dynasty's royal line. Tutankhamun ascended to the throne around the age of nine and reigned until his death around the age of nineteen.
AfterlifeThe afterlife or life after death is a purported existence in which the essential part of an individual's stream of consciousness or identity continues to exist after the death of their physical body. The surviving essential aspect varies between belief systems; it may be some partial element, or the entire soul or spirit, which carries with it one's personal identity. Belief in an afterlife is in contrast to the belief in oblivion after death.
