leukotsüütidede

Leukotsüütidede, commonly known as white blood cells or leukocytes, are a vital component of the immune system. They are produced in the bone marrow and circulate throughout the body in the blood and lymphatic system. Their primary function is to defend the body against infections and diseases.

There are several types of leukotsüütidede, each with a specialized role. Granulocytes include neutrophils, eosinophils, and basophils, which are involved in fighting bacterial and parasitic infections and mediating allergic reactions. Lymphocytes, such as B cells, T cells, and natural killer cells, are crucial for adaptive immunity, recognizing and destroying specific pathogens, and producing antibodies. Monocytes differentiate into macrophages, which engulf and digest cellular debris, foreign substances, and pathogens.

The number of leukotsüütidede in the blood can indicate various health conditions. An elevated white blood cell count, known as leukocytosis, often suggests an ongoing infection or inflammation. Conversely, a low white blood cell count, or leukopenia, can weaken the immune system and make an individual more susceptible to infections. Certain medical conditions, medications, and treatments like chemotherapy can also affect leukotsüütide counts. Monitoring leukotsüütide levels is a common diagnostic tool in medical practice.
