1.Anatomy- studies the structure of of body parts and their relationships to one another.

Subdivisions of anatomy:

. Gross or macroscopic anatomy- the study of large body structures visible to the naked eye, such as lungs, heart, and kidneys.

subdivisions of gross anatomy:

. regional anatomy-when all the structures (muscles, bones, blood vessels, nerves, etc.) in a particular region of the body are examined at the same time.

. systemic anatomy- the anatomy of the body  is studied system by system.

.surface anatomy- the study of internal structures as they relate to the overlying skin surface. (done with subs of gross anatomy)

. Microscopic anatomy- concerns structures too small to be seen with the naked eye, studied under microscopes

subdivision of microscopic:

. cytology- concerned with the cells of the body

.histology- the study of tissues

.Developmental anatomy- traces structural changes that occur in the body throughout the life span

.Embryology- concerns developmental changes that occur before birth

Physiology- the function of the body, how all the body parts work and carry out their life sustaining activities

subdivisions of physiology

.renal physiology- kidney function and urine production

.neuro physiology- explains the workings of the nervous system

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