What is the Largest Vein in the Body?
Answer – The largest vein in the human body is the inferior vena cava.
Explanation:
The inferior vena cava is the largest vein responsible for carrying deoxygenated blood from the lower half of the body back up to the heart (right atrium). It is located slightly off-center, toward the right side of the body. Its length varies depending on the individual but, on average, it is approximately 2–3 inches (i.e. 5–7.5 centimeters). The diameter of the vein is reported to be 15–20 mm (i.e. 1.5–2 centimeters).
