Document Summary

Anatomy: the science of structure and the relationships among structures. Physiology: the science of body functions (structure of a part determines how it will function) Histology: the science of the microscopic structure of biological material (ways in which individual components are structurally and functionally related) Organization and the body collection of atoms held together by chemical bonds.

The organization of the human body is connected to the environment. Raw materials: atoms and molecules; during embryonic development to form cells (and body); after birth, - to add new molecules to cells and body during growth, -replenish previously existing molecules that are lost, used up, or destroy. Energy: maintain the molecular structures of cells (to keep chemical bonds from breaking apart), to.
