Understanding White Blood Cells (Leukocytes)
White blood cells, also known as leukocytes, are a crucial component of the immune
system. They are responsible for protecting the body from pathogens such as bacteria,
viruses, fungi, and parasites. Unlike red blood cells, which primarily carry oxygen, white
blood cells are involved in immune responses and are capable of moving through tissues
to reach sites of infection or injury.
