Vascular supply was the network of arteries, vein, and capillaries in the humanoid body which supplied blood to the circulatory system.
In the humanoid brain, the frontal lobe was the vascular supply for the organ and the temporal lobe was the location of the mid cerebral vascular.
In 2370, in the "Anatomical Scan – 9861" for Juliana Tainer, the vascular supply was listed under the coronal plane portion of the graphic. For her vascular supply, it was noted that her supply was 12.73% below normal. (TNG: "Inheritance")
