Answer:

Through blood vessels

Explanation:

Bones are made up of osseous connective tissue. These osseous connective tissues are made up of sparse cells within the extracellular network, or matrix . This matrix is made up of protein and minerals. The bone cell named Osteoblasts provides tensile strength to the bone by releasing proteins into the matrix. Collagen is the protein part of this bone matrix while the remaining part of bone matrix is made up of minerals  which provide hardness and compressive strength. Bone cells are living cells and they receive nourishment through the blood. The food delivery and waste removal is done by the blood vessels which pierce into the hard compact surface of the bone.
