The main feature of chemotaxis is:
Increased random movement of neutrophils
Increase adhesiveness to intima
Increased phagocytosis
Unidirectional locomotion of the neutrophils
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.
