What happen when i remove my manager as project owner or remove from project?

I know that I can add/remove or set someone in my team to be a project owner. I dont know if I set the member to be a project owner, what happen with my manager? She will be remove from project or not?

If you remove from project owner they stay a project member. If you remove from the project they can still access the project if public and if the project is within a team they have access to.

Does this help?
