Week 1 Chapter 1 1. What is the basic difference between anatomy and physiology? (p. 2) ANSWER: Anatomy (a-NAT-ō-mē; ana- = up; -tomy = process of cutting) is the science of structure and the relationships among structures. Physiology (fiz′-ē-OL-ō-jē; physio- = nature‚ -logy = study of) is the science of body functions‚ that is‚ how the body parts work. 2.

In all ages‚ thyroid hormones play a role in protein synthesis and breakdown‚ increase body heat production in times of prolonged cold weather‚ and set basal metabolic rate. Calcitonin is also regulated by the thyroid gland and is involved with calcium homeostasis between the bone and the circulation. The parathyroid glands are two sets of organs associated with the thyroid gland. The chief cells produce parathyroid hormone (PTH) whose main function is to regulate calcium
