Is bone marrow an organ?

Bone marrow can be enjoyed just like butter — spread some on a cracker or a piece of toast. You can also buy bone marrow that has already been removed from the bone.
Is bone marrow a fat?
Introduction. Bone marrow fat (BMF) is located in the bone marrow cavity and accounts for 70% of adult bone marrow volume. It also accounts for approximately 10% of total fat in healthy adults above the age of 25 years (1, 2).
How does bone marrow make blood?
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

How do you get bone marrow?

- Red blood cells transport oxygen throughout the body.
- White blood cells support the immune system to fight infection.
- Platelets are required for proper blood clotting.
