As Mrs. Includer, I like to ask you again to do the following to sum up what we’ve learned in class. (And big shout out to you! yes you!! to come all the way up to this point. Thank you for being a great A & P learner!!) 1) List FOUR components of homeostasis with their definition. 2) Pick TWO organ systems to explain how they maintain homeostasis in your body. Be specific in their relationship. 3) What is your biggest takeaway from this class? Why? 4) If you are asked to answer someone interested in taking this course next semester, what is your advice for them?
