Step 1
Explain how damaging bone marrow cells could be life threatening.
Answer
Bone marrow is essential for producing blood cells, including red blood cells and white blood cells. Damage to bone marrow can lead to a shortage of these cells, which can cause severe health issues. For example:
- Red Blood Cells: If red blood cell production is compromised, it can lead to anemia, resulting in fatigue and weakness due to insufficient oxygen supply to tissues.
- White Blood Cells: A reduction in white blood cells can impair the immune system, making the body more susceptible to infections.
- B Lymphocytes: Bone marrow also produces B cells, which are vital for antibody production. A lack of B cells can prevent the body from effectively responding to infections.
Thus, damage to bone marrow can critically disrupt essential functions, potentially leading to life-threatening conditions.
