While many people think of bone as this sturdy entity that doesn't really have much dynamic power, there is actually quite a lot of activity that goes on intrinsically in the marrow. It helps to coordinate the cartilage and the bone while also working through cycling immune cells, blood cells and various other cells in the body. For eons, the fact that marrow produces fat has been largely puzzling to so many medical professionals. After much research, in recent years a number of studies have shown that the greater the fat composition around and in the bone marrow the more susceptible to fractures and breaks that bone is.
