The Veins that Carry Oxygenated Blood
Aside from the above classification, Veins are additionally labeled by way of the kind of blood they carry. There are two forms of veins on this class:
Pulmonary veins are a sort of vein that carries oxygenated blood from the lungs to the guts. These veins are positioned within the chest and are accountable for transporting oxygenated blood from the lungs to the left facet of the guts.
