Why is bone marrow primarily red in infants?
Infants grow relatively fast and need quite a lot of red blood cells, which are only produced in red bone marrow. As the infants grow older, much of the red bone marrow is gradually replaced by yellow bone marrow containing a special kind of fat that gives it its yellowish color. If the body needs more red blood cells than the remaining red marrow is capable of producing, some of the yellow marrow changes to red marrow.
