What is the term for the attraction of white blood cells to a wound site?

The term that describes the attraction of white blood cells to a wound site is chemotaxis. This process involves the movement of immune cells toward the site of injury or infection in response to chemical signals released by damaged tissues or pathogens. These signals act as a gradient, guiding the white blood cells to where they are needed most, facilitating the body's immune response and healing process.

Phagocytosis refers to the actual process where white blood cells engulf and digest pathogens and debris, but it does not specifically describe the initial movement of these cells toward the wound. Immunization is related to the introduction of an antigen to elicit an immune response, and hemostasis pertains to the cessation of bleeding — both of which are not about the attraction of white blood cells. Thus, the correct identification of chemotaxis clarifies the role of this process in immune function and wound healing.
