A side-by-side comparison of two illustrations. On the left side there is a 3D illustration of a human skull with a red and blue blood vessel attached to it. The blood vessel appears to be a blood vessel which is responsible for the flow of blood from the skull to the brain. On the right side of the image there are two illustrations of a blue molecule with a yellow arrow pointing towards it. This molecule is likely a cell or a cell membrane. The blue molecule is surrounded by small green and purple cells which are likely the cells that are responsible for regulating the flow and regulating the blood flow. The yellow arrow is likely indicating the direction of the flow which may be caused by the blue molecule. The background of both illustrations is white and the overall color scheme is blue and green.
