Know the subsystems within each key system • Tell the order of each subsystem in that system • Know the function of each subsystem in that system schmied 2014

4. Multi Level Thinking responses • Multi level responses are responses that take an explanation to its furthest logical point. • Example: • How will exercising regularly affect your heart rate? • Initially your heart rate increases during exercise • Over time exercise makes your heart both bigger & stronger, pumping more blood with each beat (The exercise also stimulates production of new blood vessels.) • As a result, the heart will be more efficient and the heart rate will decrease both during exercise and after exercise 3 different levels of response schmied 2014

5. BODY SYSTEMS & FUNCTIONS schmied 2014
