Essentials of Anatomy and Physiology is the integrated study of the human body's structure () and how those structures function ( physiology ) to sustain life. The core principle of this field is the complementarity of structure and function , meaning the physical form of a body part is intrinsically linked to the tasks it performs. I. Levels of Structural Organization : Groups of similar cells that perform a specific function

The human body is organized into a hierarchy of increasing complexity:

: Related organs coordinating for a common purpose (e.g., the digestive system).
