What is the difference between compact and spongy bone? (2 points) Spongy bone looks like a sponge hence the name and contains a lot of red bone marrow (medulla ossium rubra). Red bone marrow is what produces red blood cells. Compact bones which consists of medulla ossium flava or yellow bone marrow, is made mostly of fat cells (Openstax College, 2013). 2.
