Por que sua veia é azul? 🤔 Se o nosso sangue é sempre vermelho, por que as veias do pulso parecem azuis ou verdes? 🩸🔵 Muita gente acha que é falta de oxigênio, mas isso é MITO! A verdade é pura física: tem a ver com como a luz atravessa a sua pele. A luz vermelha penetra fundo, mas a luz azul bate e volta para os seus olhos. Basicamente, é uma ilusão de ótica do seu próprio corpo! 🧠✨ Olha pro seu pulso: suas veias são mais azuis ou esverdeadas? 👇 #neofato #biologia #curiosidades #corpo
