Hi! I was wondering if anyone who got an A in Biology for F211 could give me a step by step method to answer these two parts of the specification:
Describe the cardiac cycle, with reference to action of the valves in the heart
Describe how heart action is coordinated with reference to the sinoatrial node (SAN) and the atrioventricular node (AVN) and the Purkyne tissue
I don't want Oxford to know I only got an A...
