Structure and Function Imune System

Introduction

The lymphoreticular system is a complex organization of cells of diverse morphology, distributed widely in different organs and tissues of the human body, and is responsible for immunity. It consists of lymphoid and reticuloendothelial compo-nents and is responsible for immune response of the host. The lymphoid cells, which include lymphocytes and plasma cells, are responsible for conferring specific immunity. On the other hand, the reticuloendothelial system, which con-sists of phagocytic cells and plasma cells, is responsible for nonspecific immunity. These cells kill microbial pathogens and other foreign agents, and remove them from blood and tissues.
