to release histamine and other mediators of inflammation

Verified step by step guidance

Understand the role of neutrophils in the immune system. Neutrophils are a type of white blood cell, specifically a type of granulocyte, that play a crucial role in the body's defense against infections.
Recognize that neutrophils are primarily involved in the process of phagocytosis, which is the engulfing and digestion of microorganisms and cellular debris.
Differentiate between the functions of various immune cells. For example, lymphocytes are responsible for mounting immune responses via antibodies, while basophils release histamine during inflammatory responses.
Identify that neutrophils are not involved in sealing blood vessel tears or killing parasitic worms. These functions are typically associated with platelets and eosinophils, respectively.
Conclude that the primary function of neutrophils is to phagocytize bacteria, which means they engulf and digest bacteria to protect the body from infections.
