OS GLOBULOS ROJOS: Si se observa en el microscopio una gota de sangre, se ve que en ella nada una multitud enorme de corpúsculos pequeñísimos de color rojo, que son los que le dan ese color. Son los glóbulos rojos de forma circular aplanada, hundida en su parte central. En todas las personas, los glóbulos rojos son de dimensiones aproximadamente iguales, de 0,007 mm de diámetro y de 0,002 mm de grosor. Pero su numero es fantástico. Una gotita pequeñísima de sangre, de 1 mm^3, contiene 5 millones de estos corpúsculos. Además, en el cuerpo humano hay un numero de litros de sangre 14 veces menor que el numero de kilogramos que pesa la persona. *
