what sql server is holding in the used memory?

I have a query that shows me how much memory sql server is using, the settings like max memory and min memory, cpu, etc. here is the query:

SELECT R.[instance],

			) K
ON R.instance = K.instance

INNER JOIN (

							SELECT [instance] = @@servername,
							CONVERT(decimal(12,2),CAST(physical_memory_in_use_kb AS DECIMAL(12,2))/1024.00) AS Memory_usedby_Sqlserver_MB,

							process_virtual_memory_low
							FROM sys.dm_os_process_memory t
		

           ) FOO
ON R.instance = foo.instance
OPTION (RECOMPILE);

this query gives me this - currently on a not busy dev server: My question is related to physical_memory_in_use_kb and locked_page_allocations_kb from the dmv sys.dm_os_process_memory. How can I find what objects or whatever sql server is holding in that memory? I can see that in my case there is a minimum memory set to 2 Gb but the memory in use is over 5Gb. It might as well be that I actually do not need to know as there is probably no memory pressure at the moment, but still, is there a way to find out what sql server is holding in there memory?
