fehérvérsejtekbl

fehérvérsejtekbl is a Hungarian term that translates to "white blood cells" in English. White blood cells, also known as 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 infectious diseases and foreign invaders.

There are several types of white blood cells, each with specialized roles. Neutrophils are the most common type and are primarily responsible for fighting bacterial infections. Lymphocytes, including T cells and B cells, are involved in the adaptive immune response, recognizing and targeting specific pathogens. Monocytes can differentiate into macrophages, which engulf and digest cellular debris and pathogens. Eosinophils and basophils are involved in combating parasitic infections and allergic responses.

When the body detects an infection or injury, white blood cells are mobilized to the affected area. They can travel through blood vessels and tissues to reach sites of inflammation. Their actions include engulfing pathogens, producing antibodies, and releasing signaling molecules that recruit other immune cells. The number of white blood cells can increase significantly during an infection, a condition known as leukocytosis, which is often detected through a blood test. Conversely, a low white blood cell count, or leukopenia, can make an individual more susceptible to infections.
