Here you have the summary to study this weekend... I think it can help you a lot! ;)
Firtsly, WHAT YOU NEED TO KNOW:
6º A
6º B
P.D.: I think it is a good idea if you have a look at the circulatory system from 6ºA because they have the steps very clear, and it might be easier for you to study.
Considero que este blog es de gran ayuda a la hora de fijar conceptos y a estudiar de una forma mas entretenida que la propiamente convencional, muchas gracias, por vuestras iniciativas y vuestro esfuerzo, saludos de la madre de Elsa.
