The compact bone basically contains the yellow bone marrow and the yellow bone marrow is responsible for actually storing the adipose tissue. The adipose tissue or the cell contains the cells that store our fat in the form of triglycerides. Now this compact bone also is responsible for giving our bone strength, for giving our bone tensile strength as well as our compressive strength. And it's our compact bone that consists of the individual units known as osteons that we spoke about previously. So the long shaft region, the bone, is called our diaphysis. This contains our medullary cavity, also known as the marrow cavity, which is the innermost part of the bone.
