Part 2 book “Anatomy and physiology coloring workbook - A complete study guide” has contents: The endocrine system, blood, the cardiovascular system, the lymphatic system and body defenses, the respiratory system, the digestive system and body metabolism, the urinary system, the reproductive system. | 9 T HE E NDOCRINE SYSTEM The endocrine system, vital to homeostasis, plays an important role in regulating the activity of body cells. By acting through bloodborne chemical messengers, called hormones, the endocrine system organs orchestrate cellular changes that lead to growth and development, reproductive capability, and the physiological homeostasis of many body systems. This chapter covers the location of the various endocrine organs in the body, the general function of the various hormones, and the consequences of their hypersecretion or hyposecretion. THE ENDOCRINE SYSTEM AND HORMONE FUNCTION—AN OVERVIEW 1. Complete the following statements by choosing answers from the key choices. Record the answers in the answer blanks. Key Choices A. Cardiovascular system B. Hormones _ 1. _ 2. _ 3. _ 4. C. More rapid D. Nerve impulses E. Nervous system F. Slower and more prolonged The endocrine system is a major controlling system in the body. Its means of control, however, is much (1) than that of the (2) , the other major body system that acts to main tain homeostasis. Perhaps the reason for this is that the endo crine system uses chemical messengers, called (3) , instead of (4) . These chemical messengers enter the blood and are carried throughout the body by the activity of the (5) . _ 5. 193 194 Anatomy & Physiology Coloring Workbook 2.
