[Dr. Tan] There's a white matter highway between Broca's area and Wernicke's area called the arcuate fasciculus that can be communicates between the two.
These peritubular capillaries then reunite to become the cortical radiate veins, then the arcuate veins, then interlobar veins and finally into the left and right renal veins which connect to the inferior vena cava.
