Mean pulmonary vein diameters at the ostia were variable: right superior, 11.4-12.4 mm; left superior, 9.6-10.5 mm; right inferior, 12.3-13.1 mm; and left inferior, 9.0-9.9 mm. Diameter and cross-sectional area of the left superior pulmonary vein were significantly larger in men than in women (P < .005). As expected, the caliber of three of the four veins gradually increased as they approached the left atrium. Caliber of the left inferior pulmonary vein decreased as it entered the left atrium. None of the veins were round; all were ovoid. Left-sided veins and venous ostia were less round than right-sided veins (P < .001).

---- I have no clue what that means, but I hope it;s what you're looking for. I got it off of this website, which looks to be an experiment.

There are two jugular veins, an internal and an external, both of which travel inferiorly in the neck. The external jugular vein is about 3-5 millimeters in diameter (about an eighth of an inch), whereas the internal jugular vein is about 1.5-3 millimeters in diameter (about an inch).

What do you call the big vein on the side of your neck that is connected to your heart?

AnswerIt's called the carotid vein. Veins carry blood towards the heart and arteries carry it away. The vein that carries deoxygenated blood to the heart from the upper body is called the superior vena cava and the vein that carries blood from the head to that vein through the neck is the jugular vein.
