Body Cavities
 1. Dorsal Cavity:
     cranial cavity
     spinal cavity
2. Ventral Cavity
     Thoracic cavity:
             pleural
             mediastinum:
                   pericardium
    Abdominal cavity
     Pelvic cavity

anatomy = structure
physiology = function

anatomy studies the body's internal and external structures and their relationships.

 physiology examines how these structures function and work together to maintain life.

they are intrinsically linked

we will explore the
structures
of each system and how these structures dictate
function...

and how function dictate structure.

​human body  systems 

 parietal
membrane
​lines body cavity

the form of a structure dictates its function

starting with the teeniest 
​atom
molecules made from atoms

cells made from molecules

tissues made from cells

organs made from tissues

organ systems made from organs...

and there you are!

transverse

are all atoms, molecules, cells the same...
nope!
starting at the very beginning,
structure dictates function

function demands structure

it's a chicken and the egg...
