Haha oh my god THIS IS SO NOT ACCURATE AT ALL. LITERALLY, WE BELIEVED THAT BACK WHEN WE BLED PEOPLE WITH LEECHES TO CURE THE COMMON COLD.
Google it if you don’t believe me. This is what the veins of your hand look like:
Oh, and they are also connected. Your fingers do not have tiny little offshoot veins that go in every which direction and randomly either do or do not lead to the heart. They connect while within the confines of your hand:
The dorsal venous plexus of the hand and the ensuing cephalic (1) and basilic (2) veins drain the superficial aspects of the hand. The cephalic vein ends up in the axillary vein just before it becomes the subclavian and the basilic vein joins the brachial vein to become the axillary vein.
