<prompt> The main feature of chemotaxis is:Increased random movement of neutrophilsIncrease adhesiveness to intimaIncreased phagocytosisUnidirectional locomotion of the neutrophils  <response>: 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.
