Okay. Not to be a dick, but I see this everywhere and it’s like people…come on. Where the fuck do you think your other veins go? Oh, this vein from my left ring finger returns blood to my heart, all my other veins just shoot fucking blood fucking everywhere. Good lord.
All the of veins in the fingers of both your hands are similarly structured. They empty into larger veins of the hands, wrists, and arms which all eventually enter the vena cava, which directs blood to your heart to be pumped into the lungs and reoxygenated. There is not a special straight shot vein that bypasses all other vessels from your left ring finger into your heart. Please learn or never speak again. Anatomy people.
