Which is the ballooning vein on right side of neck when pressure is applied?
When pressure is applied to the right side of the neck in the lower part, emptying of the external jugular vein (blood vessel carrying deoxygenated blood back to the heart) can be blocked and it can balloon up. External jugular is a vein present on either side of the neck and it empties into the internal jugular vein behind the neck muscles. The internal jugular vein reaches the superior vena cava, the largest vein from the upper part of the body carrying deoxygenated blood to the heart. External jugular vein is sometimes used to give medications and intravenous fluids when other veins are not available. A vein is a blood vessel carrying deoxygenated blood back to the heart.
