Name: Curiosidades espaciais (bstidoresdopoder). Áudio original criado por Curiosidades espaciais. O sangue é vermelho por causa da hemoglobina, que contém ferro ligado ao oxigênio. Esse ferro foi formado em supernovas, explosões de estrelas muito massivas. Quando essas estrelas morrem, espalham elementos pesados pelo universo. Parte desse ferro acabou na Terra e, mais tarde, nos seres vivos. Por isso, podemos dizer que o ferro do nosso sangue vem das estrelas.
