Answer: "En la cabeza hay una nariz, ojos, una boca, orejas y dientes"
Explanation: Ok, here I will list five things that you can find in a human head:
Nose, or "Nariz"
Eye, or "Ojo"
Mouth, or "boca"
Theth, or "Diente"
Ear, or "Oreja"
Now that we know 5 things that are in a human head, we can write:
"En la cabeza hay una nariz, ojos, una boca, orejas y dientes"
Where i clarify "una nariz, una boca" which means "one nose, one mouth" and the other three are in plural.
