In your own words and off the top of your head: Explain the difference between anatomy and physiology. How are they related? Give one example of how form determines function

Human Body Orientation Introduction to Human Anatomy and Physiology

Anatomy - study of form or structure Other terms include shape, and appearance

Branches of Anatomy gross - large structures regional anatomy - studies all structures and their function in one region ex: abdomen, arm systemic anatomy - system by system

surface anatomy studies the external features without dissection

2. microscopic - includes cytology- study of cells and histology- study of tissues

embryology- changes before birth 3. developmental - changes from conception to old age embryology- changes before birth

4. pathological anatomy - changes caused by diseases 5. molecular biology - structure of molecules necessary for body structure and function

Physiology - functioning of body parts .

How are Anatomy and Physiology related? IMPORTANT CONCEPT A & P inseparable because function always reflects structure ex: lungs serve as site for gas exchange because air sac walls are extremely thin
