1. Describe the structure of the heart, the pattern of blood flow through the valves and chambers of the heart, how the heart as a muscle is supplied with blood, and what happens when the resting heart must suddenly supply an exercising body.

Text: Describe the THREE (3) steps involved in the cardiac cycle. In each step, you should explain the position of the valves (open/close) and the blood flow patterns into each chamber of the human heart.

A: Trace the route blood always takes to capture oxygen from the lung alveoli, carry it through the body, and then release carbon dioxide into the lung alveoli. Include all chambers and valves of the heart as well as the different types of blood vessels the blood encounters. Please include a discussion of important structural differences in the parts that improve the efficiency of the circulatory system. B: Please describe how adrenaline causes modifications to heart rate, blood vessel diameter, and bronchiole diameter that lead to increases in oxygen in the skeletal muscles. C: Please describe how one substance can cause such diverse reactions in different tissues of the body.

Short answer (answer on the back of page): Diagram the chambers, valves and cardiac conducting system of the heart. Note on your heart diagram the location of the autorhythmic vs contractile cardiomyocytes. List the events of the cardiac cycle of the left heart. How is a cardiac action potential different from a skeletal muscle action potential? List the order of the cardiac conducting system.
