The correct answer to this question is B, B. The internal jugular vein is a paired vein. This vein collects blood from the superficial parts of the face, neck, and the brain. The blood that is carried is oxygen depleted. The collected blood is then sent to the heart, by way of the superior vena cava.
The internal jugular vein can be found in the carotid sheath. It is there along with the vagus nerve and common carotid artery. Usually, two of these veins can be found on each side of the neck. Both veins help in the transport of blood, the left ones are generally smaller.
