Choose the structures that most directly provide nutrients and remove wastes from osteocytes in compact bone.
Ber [7]
I had to look for the missing options of this question and here is my answer:

Osteocyte is the term that describes the cells of the bone. These cells are formed in the mesenchyme. Once the bone matures, the processes then take place inside the Lacunae and the Canaliculi, respectively.
