Where does the venous blood from the heart enter?
This is a question on my bioscience assignment that I;'m a little confused about. If it was just 'where does venous blood enter the heart' I would say the right atrium via the inferior and superior vena cava, but the way the question is written is making me wonder if that is the answer or not...

You're right. If it had said, "Where does venous blood enter the heart?" the answer would be obvious. However, it appears that the question asks about the heart's own blood supply. If so, it's asking about the coronary sinus, which is a collection of veins that form a large vessel that collects blood from the myocardium. Then, it delivers deoxygenated blood to the right atrium.
I'd ask about that wording...
