1 Applegate: The Anatomy and Physiology Learning System, 3 rd Edition Chapter 1: Introduction to the Human Body TRUE/FALSE 1. The cell is the simplest living unit of organization within the human body. T 2. The body system that transports oxygen to body cells is the respiratory system. F Blood in the cardiovascular system transports oxygen. 3. The part of metabolism that synthesizes large molecules from smaller ones is called catabolism. F Anabolism is the building-up process. 4. Anabolism is the building-up process. T 5. When your body needs water, you get thirsty, then you get a drink. This is an example of a positive feedback mechanism because you take a positive action by getting a drink. F It is negative feedback because taking a drink removes the stimulus. 6. In anatomic position your arms are at your sides and palms are facing forward. T 7. If you are standing on your head, your eyes are inferior to your mouth. F

2 2 Remember that directional terms refer to anatomic position. 8. The longitudinal plane that divides the body or an organ into anterior and posterior regions is the sagittal plane.
