Human body to comparative physiology and ecophysiology. Most recently, evolutionary physiology has become a distinct subdiscipline. Human body The human body is the structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body. It comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. The study of the human body involves anatomy, physiology, histology and embryology. The body varies anatomically in known ways. Physiology focuses on the systems and organs of the human

In most countries plastinated human specimens are classified under Customs Classification Code 97050000.48 "items in anatomical collections". This customs code encompasses "zoological, botanical, mineralogical or anatomical collections or items in such collections." In an ethical analysis, Thomas Hibbs, professor of ethics and culture at Baylor University, a private Baptist-affiliated institution, compared cadaver displays to pornography, in that they reduce the subject to "the manipulation of body parts stripped of any larger human significance."
