      es difucion simple?​

Answer 1

Respuesta:

Esto se conoce como oxigenación cerebral, el cerebro necesita una cantidad muy elevada de oxigeno se sabe que consume alrededor del 20% del oxigeno total del organismo. Cuando ocurre un evento físico tal como el ejercicio el cerebro se oxigena naturalmente ya que al elevarse el ritmo cardíaco la cantidad de oxigeno que pasa a través de nuestra sangre se eleva.
