The main feature of chemotaxis is:
After exiting the circulation, leukocytes move in the tissues toward the site of injury by a process called chemotaxis, which is defined as locomotion along a chemical gradient. Both exogenous and endogenous substances can act as chemo-attractants.
Increased random movement of neutrophils
Increase adhesiveness to intima
Increased phagocytosis
Unidirectional locomotion of the neutrophils
Oxygen dependent bacterial killing
