Module 2 The Endocrine System

In the first unit of Biology 30, you examined the structure and function of the nervous and endocrine systems in detail. Specifically, you worked on

• describing how the nervous and endocrine systems maintain homeostasis
• explaining how the human body maintains equilibrium between its internal and external environments
• describing what physiological processes and control systems are involved in maintaining homeostasis
• analyzing what medical technologies are available to treat disorders of the nervous and endocrine systems

You saw how humans interact with their internal and external environments, and how the nervous and endocrine systems respond to maintain equilibrium and system health. Your exploration showed you the role of technology in detecting, analyzing, and enhancing the functions of these systems.

There were two modules in this unit. The first module looked at the nervous system, which responds to internal and external stimulation. Here you explored how the nervous system communicates this information throughout the body. The second module focused on the role of the endocrine system and how it works to support homeostasis by releasing hormones into the blood.
