The Immune system and the Skeletal System

By Anna

The immune system relies heavily on the skeletal system. The skeletal system plays a key role in the immune system because it creates the beginnings of T and B cells. The T and B cell beginnings are created in the yellow bone marrow. The T and b cells are created by the yellow marrow making stem cells- cells that can turn into a various different types of cells. Depending on where they go after production in the yellow marrow, the stem cells will become different things.

There are different places T and B cells go to fully develop. T cells go to the thymus, located in front of the heart. Once there, they are educated, then turned loose to roam the body looking for infections. B cells, on the other hand, go to the spleen. In the spleen, they are taught and released back into the bloodstream. As you can see, without the Skeletal system's bone marrow, we wouldn't have any white blood cells, and therefore no immune system.

Fun facts!!!
  • Your bones make your blood! (or your blood cells, anyway.)
  • Stem cells are one of the only cells in the body to not have a specific funtion! (this only lasts until they are taught to be specialized cells, though.)
  • Yellow Marrow makes stem cells, but red marrow makes red blood cells!
