Yellow marrow stores fat.

Bone marrow comes in two forms with distinct roles: red marrow, which performs hematopoiesis to produce red blood cells and other blood cells, and yellow marrow, which is mainly adipose tissue that stores fat. In adults, yellow marrow fills most medullary cavities and serves as an energy reserve by housing fat in adipocytes. That makes the statement true: yellow marrow stores fat as its primary content. The production of red blood cells and immune cells happens in red marrow, not yellow marrow, and filtering toxins is a function of liver and kidneys, not bone marrow.
