White blood cells are also known as leucocytes. White blood cells are an important part of the immune system and are responsible for protecting the body from disease and infection. Leucocytes, also known as white blood cells, are produced in the bone marrow and are a type of blood cell that is not involved in the transport of oxygen. Instead, they play a critical role in the immune response by identifying and fighting foreign invaders, such as bacteria, viruses, and other harmful substances. There are several different types of leucocytes, each with a specific function, including phagocytes, which engulf and destroy invading pathogens, and lymphocytes, which help to coordinate the immune response and produce antibodies. The number and types of leucocytes in the blood can change in response to infection, inflammation, or other factors, and are an important part of the body's defense against disease.
