Answer
Bone marrow produces blood cells which are crucial for the immune system and overall bodily functions. When bone marrow is damaged, it can lead to a lack of blood cells, resulting in symptoms such as anemia, increased susceptibility to infections, or impaired blood clotting. Consequently, this can make the body more vulnerable to various diseases and infections, which can be life-threatening.
