The
anatomy and
physiology of
organisms can be studied at different
levels of organization. Each level of organization has the
emergent properties of all the previous levels of organization.
In
anatomy and
physiology, there are six basic levels of organization:
Molecular
-
Atoms are the particles of specific elements, and combine to form more complex molecules. Different molecules have properties that determine how they interact with other molecules.
Cellular
Tissue- Tissues are composed of many cells working together for a common purpose.
Organ
Organ system
Organism
