Ownership of pages and spaces

I would like to understand more about how ownership and access works in confluence. 

1 - Person A is the owner of some pages in space X. Then the access to space x for Person A is removed. Does this mean that person A also loses access to the owned pages? 

2 - Person A user profile is deleted but is still the owner of some pages and/or spaces in Confluence. What happens to these pages and spaces when the owner is deleted?

Thank you for your help!
