The human heart is shaped like a small, crooked, oval with veins at the top.
Human veins are categorized into several major groups, with the most notable being the superior and inferior vena cava, which return deoxygenated blood to the heart. Other important veins include the jugular veins (draining the head and neck), the subclavian veins (from the arms), and the femoral veins (from the legs).
