The human body needs an army of cells to fight viruses & bacteria. If we lack supply from these cells, we may have a strong tendency to get ill.
Our body has a defense mechanism to defend our body from foreign bacterias and viruses also known as Pathogens that can harm our body and cause severe medical conditions.
If these pathogens get into our body, our body triggers to activate the White Blood Cells(leukocytes or leukocytes) to eliminate the foreign bacterias to prevent the spread of infection.
Your body should have enough 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L) in order to fully protected your body.
