Chapter One: The Human Body: An Orientation Quiz
What is the order or hierarchy of structures within the body?
1 - Cells 2 - Tissues 3 - Organs 4 - Organ Systems 5 - Organisms cells --> tissues --> organs --> organ systems --> organism
Explain the principle of complementarity
Anatomy and physiology are inseparable because what a structure can do depends on its specific form; function always reflects structure

9) The heart lies in the ________ cavity. A) superior mediastinal B) pleural C) dorsal D) pericardial
Answer: D
Give an example of the principle of Complementarity in your body
Bones can support and protect body organs because they contain hard mineral deposits. Blood flows in one direction because the heart has valves that prevent backflow
