Which type of white blood cells are responsible for fighting infection and consuming dead tissue?

The correct choice is leukocytes, which is a broad term encompassing various types of white blood cells that play critical roles in the immune response. Leukocytes are essential in the body’s defense against infections and in the removal of dead tissue. Within this category, there are several specialized cells that perform specific functions.

Neutrophils, for instance, are indeed a type of leukocyte and are among the first responders to sites of infection, effectively engaging in phagocytosis to consume pathogens and dead cells. However, leukocytes as a whole include various cell types like monocytes and lymphocytes that also contribute to the body's immune response in different ways.

Monocytes, specifically, can differentiate into macrophages, which also play a significant role in phagocytosing debris and pathogens. Lymphocytes, on the other hand, are primarily involved in the adaptive immune response through the production of antibodies and the activation of other immune cells.

In summary, while specific types of leukocytes, such as neutrophils and monocytes, have distinct roles in fighting infection and cleaning up dead tissue, the term leukocytes encompasses all white blood cells responsible for these functions. Therefore, recognizing leukocytes as the overarching category that includes all defensive white blood cells is
