has a certain
appeal .

Body structures can

examined You don't imagine
be seen , felt , and closely
.
need to what they

Concerns the function of the
body how the
body parts work in other words ,

and their life sustaining activities when all is said and done
carry out , ,

physiology is explainable only in terms of the underlying anatomy .

Topics of Anatomy
Gross Anatomy is the
study of large body structures visible to the naked eye
. Such as

the heart lungs and
, , kidneys.
The term
anatomy relates most closely to
gross anatomy because in such studies

preserved animals or their organs are dissected to be examined

.
observation manipulation and in living person palpation (feeling organs with your hand
, ,
a

and auscultation
(listening to organ sounds with a stethoscope).

Topics of Physiology
Renal
physiology concerns kidney function and urine
production

Neurophysiology explains the workings of the nervous system .

cardiovascular physiology examines the operation of the heart and blood vessels
.

complementarity of structure and Function

complementarity of structure and function is the relationship between a structure

and its function
. STRUCTURE DETERMINES FUNCTION !!!
