Respuesta :

Phagocyte mobilization is a process that has the purpose of getting the macrophages and neutrophils from where they are to where they should be. This process has four steps. These are:

1) Leukocytosis
2) Margination
3) Diapedesis
4) Chemotaxis

Chemotaxis is the final step of the mobilization. It is where a trail of 
neutrophils follow the concentration gradient towards the injured area.

Answer:

Neutrophils and other WBCs migrate up the gradient of chemotactic agents to the site of injury

Explanation:

Phagocytes move up concentration gradients of attractive chemicals (chemotactic agents) released from damaged tissue and inflammatory cells.
