Tongue Vasculature: Arteries and Capillaries, No Veins

The tongue receives arterial supply from the lingual artery (branch of external carotid) and has a rich capillary network. Venous drainage occurs via the lingual veins, but the tongue itself does not contain distinct venous structures (veins/venules) within its substance—only capillaries that converge into draining veins at the periphery.
