Descrizione:

Ooh, what's this hole right on the bottom of my face, and those two other holes in the middle. I'll call them my nose and mouth. Wait, I can think, oh yeah, by brain is forming. There are also these long tubes in my abdomen, maybe they're my intestines. American Psychological Association, American Psychological Association, www.apa.org/education/k12/brain-function.aspx.
