Now I'm a little nervous, because I can't remember what the wording on the last question was. After I saw the word coordination and heart, I just started writing about how the ventricles are always made to contract after the atria (by the SAN, AVN, etc. as was mentioned before), as did my friends who did the exam with me. Anybody else remember what the question asked for?

It basically asked about how the blood circulated in the four chambers of the heart in the pulmonary and systemic circulatory systems. You had to mention how the muscles contracted and relaxed, the valves that open and close, and which chambers are connected to which veins/arteries.

You have to mention the AVN and SAN as a part of your answer as they are responsible for the contractions and relaxations that occur during the blood circulation.

i think plus my work i have added them; i don't remember for now

Great, so that's probably at least a couple marks lost because I forgot to read the question carefully. I hope they have lots of marks for going into detail about the rhythm, but that seems fairly unlikely at this point :/
