You are coaching a little league team and are playing a double-header on a very hot day. One of your players, a very curious 13 year old girl wonders why Gatorade advertises the presence of electrolytes in their beverages as beneficial to athletes. How would you explain to your player that electrolyte and water balance in the body are dependent upon each other? Be sure to let her know how we acquire water and electrolytes, their importance within the body, and how we regulate that balance in varying conditions.

You were the top student in your physiology class last semester. For this reason, your professor has asked that you prepare some lectures for her physiology class this semester. Specifically, she would like you to discuss the similarities and differences between the cardiovascular and respiratory systems, in terms of pressure gradients and fluid flow. A. Explain how you will describe the role of the following structures: the pump and the tubes. B. Explain how you will describe the importance of an open vs. closed system and the relevant differences between liquids and gases. C. What is fundamentally different about the respiratory pump compared to the cardiac pump, and why does this difference exist?
