The table that summarizes the functions of the cells and chemicals of the innate defense mechanisms of mammals. Introduction: The immune system protects the body from the invading pathogenic organisms. The immune system is classified into two types, namely the innate immune system and adaptive immune system. The innate immune system is the defense mechanism found already from the birth whereas the adaptive immune system is acquired at the later stages of life when exposed to antigens. The white blood cells that involve in innate immunity are natural killer cells, mast cells, eosinophils, basophils, macrophages, neutrophils, and dendritic cells.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Toll-like receptors represent an ancient pathogen-recognition system. The first pattern recognition receptor (PRR) important in innate immune responses was discovered in the fruit fly Drosophila melanogaster. Stimulation of this receptor, called Toll, induces: The synthesis of prostaglandins and leukotrienes The inflammatory response in Drosophila hemolymph vessels The production of antimicrobial peptides The recruitment of phagocytic cells to the site of infection The activation of Drosophila complement
