How many large vessels depart from the human heart? Count by the holes for the vessels in the chambers

How many large vessels depart from the human heart? Count by the holes for the vessels in the chambers of the heart – if a vessel branches out after leaving the heart, count it as one vessel?

The vessels through which blood flows from the heart are called arteries, and through which it returns to it – veins. There are two veins per artery in the body.

The aorta emerges from the left ventricle, and two pulmonary arteries emerge from the right ventricle. The superior and inferior vena cava approach the right atrium, and four pulmonary veins approach the left atrium. If you count through the holes for the vessels in the chambers of the heart, then nine large blood vessels depart from it.
