Those relationships are stored in a hidden entity called listmember. However, you can't retrieve those records directly. You'll have to do a retrieve on the contact entity, join it to list member, and then filter it based on the listid of the marketing list. Here's an example.

To remove someone (as you mentioned in the title), you'll need to execute a RemoveMemberListRequest. The SDK has the details.
