1. Smooth muscle is a tissue type. Using examples, discuss the level of body organization "below" smooth muscle tissue and the level of body organization "above" smooth muscle tissue.

2. Arteries transport blood away from the heart and veins transport blood toward the heart. Using the terms proximal, distal, medial, and lateral, describe blood flow from the heart to the right thumb and back to the heart. In answering this question, keep anatomical position in mind. Also, be aware that adding an "ly" to these directional terms changes them from nouns to adjectives.

3. Using an example other than the ones described in this chapter, explain how a feedback mechanism works. Why is homeostasis a state of dynamic constancy rather than a steady state?

4. During your next physical examination, the physician may assess the condition of some of the organs and structures in your body through the techniques of palpation, percussion, and auscultation. Describe how each of these techniques may be used for a particular body organ or structure.

5. Physicians used to believe that following childbirth a woman should be confined to bed for a minimum of 5 days. Design an experiment consistent with the principles of the scientific method to determine the effect of inactivity on recovery time of postpartum women.
