Anatomy

Describe the structures of the body

Physiology

Study of functions of anatomical structures

How are anatomy and physiology inseparable?

The function always reflects the structure, the structure dictates the function

organ systems

clinical anatomy

medical specialties

Developmental anatomy

From conception→adulthood including embryology

Cell physiology

function of cells

Organ physiology

function of specific organs

systemic physiology

function of organ systems

effects of diseases on organs/systems
