Document Summary
Early interest in the human body probably developed as people became concerned about injuries and illnesses. Early doctors began to learn how certain herbs and potions affected body functions. The idea that humans could understand forces that caused natural events led to development of modern science. A set of terms originating from greek and latin formed the basis for the language of anatomy and physiology. Much of what we know about the human body was discovered using the scientific method. Anatomy: greek word for cutting up; structures. Physiology: greek word for relationship to nature; functions. Anatomy deals with the form and organization of body parts. Physiology deals with the functions of these parts. The function of a part depends upon the way it is constructed: physiology is based on the anatomy of a body. The body is composed of parts that can be considered at different levels of organization. Matter is composed of atoms, which are composed of subatomic particles.
