Leukocytes (leucocytus; from the Greek λευκός - white and κύτος - cell; synonym - white blood cells) are blood cells that play an important role in the immune system. They are responsible for protecting the body from infections and other damage.
White blood cells are produced in the bone marrow and circulate throughout the body in the blood and lymph. During infection or inflammation, their amount in the blood increases. This phenomenon is called leukocytosis.
There are several types of white blood cells, each of which performs its own specific functions:
-
Neutrophils are the first to arrive at the site of inflammation and destroy pathogens.
-
Eosinophils - participate in the fight against parasitic infections and allergic reactions.
-
Basophils - release histamine and other substances involved in inflammation.
-
Monocytes - phagocytose microorganisms and produce cytokines.
-
Lymphocytes are key cells of the immune system, responsible for a specific immune response.
Thus, leukocytes are the most important blood cells that support the immune system and protect the body from pathogens and damage.
Leukocytes, or white blood cells, are one of the main components of human blood. They are cells that protect the body from infections and other external influences. White blood cells perform an important function in the immune system, protecting the body from bacteria, viruses and other pathogens.
White blood cells are shaped like round or oval cells that can be colored in different colors depending on their function and type. There are several types of white blood cells, each of which has a different role in the immune system. For example, neutrophils are responsible for fighting bacteria and destroying infected cells, while lymphocytes are responsible for producing antibodies to fight viruses and other infections.
It is important to note that white blood cells not only protect the body, but also participate in other processes, such as regulating body temperature, blood clotting, etc. A change in the number of white blood cells in the blood can indicate the presence of various diseases, such as cancer, autoimmune diseases and others. Therefore, it is important to monitor your health and get blood tests regularly.
