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 body and their functions.

He noted that body cells survived in a healthy condition only when the temperature, pressure, and chemical composition of their environment remained relatively constant. Later, an American physiologist, Walter B.
