Why Your Veins Look Blue Even Though Blood Is Red ? 🔵🩸 - - Arterial blood looks bright red because it carries more oxygen, while venous blood looks darker (deep maroon) because it has less oxygen bound to hemoglobin. Veins can look blue or green through the skin because light gets absorbed and scattered in tissue: red light is absorbed more on the way down and back, while shorter wavelengths return to your eyes more easily. Depth of the vein, skin thickness, and lighting can all change the color you think you see. - - 🎥 Video created by 🩺 (Dr._Bahaa_N_Dmour), CEO & Founder of Smart Doctor 🪄 - - - - #Anatomy #Education #Smartdoctor1 #DrBahaaDmour #dr_bahaa_dmour
