Are human beings matter or psych? why?

I think that human beings are both. matter because occupies a space in the universe and are formed by mass compound for blood, muscles, tissues etc.
And for Psych because is who regulates the functioning of the body. With psych you can think and reason.
They work together, the body makes that psych said.
a body can not function without a psych, and a psych without a body.
both are a complement.
We didnt understand to human being for separate psych and matter.
