palpate the vein with the tip of your index finger
"Palpate" a vein.... This is an acquired skill. A vein will have an elastic feel when lightly compressed and then released. There will also be a "collapse" sensation when it is compressed that will be distinctly different than the surrounding tissue. As most veins suitable for drawing blood will run along the long axis of the extremity these sensations should be detectable as you trace the path of the vein. The best way to learn is to start by palpating visible veins, then following the path of the vein as in passes deeper in the surrounding tissue. You may be surprised how far you can feel the vein once you do some practicing. With a constriction band (tourniquet) in place the feel of the vein will be more pronounced. Practice palpating a vein without one to get good at it!

Superior Vena Cava
vena cava
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.
