Play Anatomy Introduction

Anatomy

studies the structure of body parts and their relationship to one another

Physiology

the function of the body parts

Levels of Organization

Atom - molecule - macromolecule - organelle - cell - tissue - organ - organ system → organism

Homeostasis

Maintain relatively stable internal conditions

Negative Feedback

feedback: reduces effect of stimulus Eg. body temp, breathing rate, blood sugar levels

Positive Feedback

feedback: increases response Eg. labor contractions, blood clotting

Anatomical Position

Body erect, feet slightly apart, palm face forward, thumbs pointing out
