The document discusses the structural organization of the human body from smallest to largest: chemicals make up cells, cells combine to form tissues, tissues combine to form organs, organs group together to form organ systems, and organ systems combine to form a unique human organism. Studying the body's basic construction from smallest to largest parts is helpful for understanding its different structures and functions. The organization of the body is often discussed in terms of these increasing levels of complexity.

Structural Organization of the Human Body

3.  Before you begin to study the different structures and functions of the
human body, it is helpful to study its basic construction; that is, how
its smallest parts are assembled into larger structures.
 It is useful to consider the structures of the body in terms of
fundamental levels of organization that increase in complication, such
as (from smallest to largest): chemicals, cells, tissues, organs, organ
systems, and an organism.
 The organization of the body often is discussed in terms of the different
levels of increasing complexity, from the smallest chemical building
blocks to a unique human organism.
