White Blood Cells | Community Health

White blood cells, also known as leukocytes or immune cells, are a crucial part of the body's immune system, responsible for protecting against infectious diseases and foreign entities. With three main subtypes - granulocytes, lymphocytes, and monocytes - these cells are produced in the bone marrow from hematopoietic stem cells and can be found throughout the body, including the blood and lymphatic system. According to the National Institutes of Health (NIH), white blood cells play a vital role in the body's defense mechanism, with approximately 4,500 to 11,000 white blood cells per microliter of blood in a healthy individual. The World Health Organization (WHO) emphasizes the importance of a well-functioning immune system, highlighting the role of white blood cells in preventing and fighting diseases. With a vibe score of 80, white blood cells are a fundamental aspect of human health, and their dysfunction can lead to various chronic conditions, such as leukemia, lymphoma, and immunodeficiency disorders, as noted by the Centers for Disease Control and Prevention (CDC).
