19 Facts About Bone marrow
2.
Human Bone marrow produces approximately 500 billion blood cells per day, which join the systemic circulation via permeable vasculature sinusoids within the medullary cavity.

3.
Composition of Bone marrow is dynamic, as the mixture of cellular and non-cellular components shifts with age and in response to systemic factors.

4.
In humans, Bone marrow is colloquially characterized as "red" or "yellow" Bone marrow depending on the prevalence of hematopoietic cells vs fat cells.

5.
At the cellular level, the main functional component of bone marrow includes the progenitor cells which are destined to mature into blood and lymphoid cells.

7.
Stroma of the bone marrow includes all tissue not directly involved in the marrow's primary function of hematopoiesis.

8.
Bone marrow stroma contains mesenchymal stem cells, which are known as marrow stromal cells.

9.
Blood vessels of the bone marrow constitute a barrier, inhibiting immature blood cells from leaving the marrow.

10.
Red bone marrow is a key element of the lymphatic system, being one of the primary lymphoid organs that generate lymphocytes from immature hematopoietic progenitor cells.

15.
When "yellow" fatty Bone marrow becomes replaced by tissue with more cellular composition, this change is apparent as decreased brightness on T1-weighted sequences.

16.
Normal "red" Bone marrow is typically equivalent or brighter than skeletal muscle or intervertebral disc on T1-weighted sequences.

18.
The bone marrow produces the cellular elements of the blood, including platelets, red blood cells and white blood cells.
