Strategy to Succeed and Homeostasis

Anatomy and Physiology can be a daunting (but also exciting!) course. We will cover every body system in this course and Anatomy and Physiology II. It’s a good idea to take a moment this week to self-reflect and get yourself organized for the upcoming term.

Throughout this course, we will often return to a common principle which regulates the human body: homeostasis. For your discussion post, provide one example of homeostasis within the body. Provide a brief 3-4 sentence explanation of the example you choose.

Additionally, identify and discuss 1-2 obstacles you may face with this course while learning anatomy and physiology. Examples may include being new to online learning, time management issues, personal or family commitments, test anxiety, etc.
