34. The heart is divided into two major sections with two chambers in each section. Tell an easy way to remember which section carries oxygenated blood and deoxygenated blood, the chamber the blood enters first, and the second chamber the blood exits from.

Question

I think the chamber that blood enters first is pulmonary arteries...? and it exits from aorta?
Well, I need help on this..especially with the first part of an easy way to remember which section carries what blood.

Thanks
