What is the relationship between anatomy and physiology

anatomy is the study of form and structure, physiology is the study of function

How might knowledge of surface anatomy be important for a healthcare worker during a CPR emergency

Answer!

Form and and function are interrelated, meaning that ______ them is the best way to study both

integrating

Form _____ function

follow

what is the meaning of ‘form follows function’

structures are designed to perform their specific function

what is the meaning of “form allows function”

once we understand structure we can understand its functions
