1 answer

The two correct answers are:

  1. Bone marrow - Bone marrow is where blood cells, including white blood cells, are produced. It plays a crucial role in the immune system.

  2. White blood cells - White blood cells are a key component of the immune system and are produced in the bone marrow.

So, the skeletal system produces both bone marrow and white blood cells that help the immune system defend the body.
