Fehérvérsejtekben

Fehérvérsejtekben, often translated as white blood cells or leukocytes, are a crucial component of the immune system. They are produced in the bone marrow and circulate in the blood and lymph. Their primary function is to defend the body against infection and disease. There are several different types of white blood cells, each with specialized roles. Neutrophils are the most abundant type and are important for fighting bacterial infections. Lymphocytes include T cells, B cells, and natural killer cells, which are involved in adaptive immunity, producing antibodies, and directly attacking infected or cancerous cells. Monocytes can differentiate into macrophages, which engulf and digest cellular debris and foreign substances. Eosinophils and basophils are involved in fighting parasitic infections and allergic reactions. When the body detects an invasion by pathogens like bacteria, viruses, or fungi, or the presence of abnormal cells, white blood cells are mobilized to the site of concern. They can identify, neutralize, and eliminate these threats through various mechanisms, including phagocytosis (engulfing and destroying foreign particles) and the release of chemical substances. An abnormal count of white blood cells, either too high or too low, can indicate an underlying health issue, such as infection, inflammation, autoimmune disorders, or leukemia.
