Embalming is the art and science of preserving human remains by treating them (in its modern form with chemicals) to forestall decomposition. This is usually done to make the deceased suitable for viewing as part of the funeral ceremony or keep them preserved for medical purposes in an anatomical laboratory. The three goals of embalming are sanitization, presentation, and preservation, with restoration being an important additional factor in some instances. Performed successfully, embalming can help preserve the body for a duration of many years. Embalming has a very long and cross-cultural history, with many cultures giving the embalming processes a greater religious meaning.
Animal remains can also be embalmed by similar methods, but embalming is distinct from taxidermy. Embalming preserves the body intact, whereas taxidermy is the recreation of an animal's form often using only the creature's skin, fur or feathers mounted on an anatomical form.
Whilst the term embalming is used for both ancient and modern methods toward preservation of a deceased person, there is very little connection between modern-day practices of embalming and ancient methods in terms of techniques or final aesthetic results.
The Chinchorro culture in the Atacama desert of present-day Chile and Peru are among the earliest cultures known to have performed artificial mummification, as early as 5000–6000 BCE. The earliest known evidence of artificial preservation in Europe was found in Osorno (Spain) and are about 5000 years old human bones covered in cinnabar for preservation, but embalming remained unusual in Europe up to the time of the Roman Empire.
Perhaps the ancient culture that developed embalming to the greatest extent was Egypt. As early as the First Dynasty (3200 BCE), specialized priests were in charge of embalming and mummification. They did so by removing organs, ridding the body of moisture, and covering the body with natron. The ancient Egyptians believed that mummification enabled the soul to return to the preserved corpse after death.

A cadaver or corpse is a dead human body. Cadavers are used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being. Students in medical school study and dissect cadavers as a part of their education. Others who study cadavers include archaeologists and arts students. In addition, a cadaver may be used in the development and evaluation of surgical instruments.
A mummy is a dead human or an animal whose soft tissues and organs have been preserved by either intentional or accidental exposure to chemicals, extreme cold, very low humidity, or lack of air, so that the recovered body does not decay further if kept in cool and dry conditions. Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least 1615 AD.
A coffin is a funerary box used for viewing or keeping a corpse, either for burial or cremation. Coffins are sometimes referred to as a casket, particularly in American English. Any box in which the dead are buried is a coffin, and while a casket was originally regarded as a box for jewelry, use of the word "casket" in this sense began as a euphemism introduced by the undertaker's trade.
In this work a numerical strategy to address the solution of the blood flow in one-dimensional arterial networks through a topology-based decomposition is presented. Such decomposition results in the local analysis of the blood flow in simple arterial segm ...
