The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants, fungi, prokaryotes, and invertebrates (see Beyond vertebrates). [2 ...
The other cells involved in the innate response include innate lymphoid cells, mast cells, eosinophils, basophils, and natural killer cells. [ 28 ] Phagocytosis is an important feature of cellular innate immunity performed by cells called phagocytes that engulf pathogens or particles.
Non-specific immunity, or innate immunity, is the immune system with which you were born, made up of phagocytes and barriers. Phagocytosis , derived from the Greek words phagein , meaning to eat, kytos or cell, and “osis” meaning process, was first described by Élie Metchnikoff , who won the Nobel Prize 100 years ago.
The immune system has innate and adaptive components. Innate immunity is present in all metazoans , [ 1 ] immune responses: inflammatory responses and phagocytosis . [ 2 ] The adaptive component, on the other hand, involves more advanced lymphatic cells that can distinguish between specific "non-self" substances in the presence of "self".

The study of the molecular and cellular components that form the immune system, including their function and interaction, is the central science of immunology. The immune system is divided into a more primitive innate immune system and an acquired or adaptive immune system of vertebrates, each of which contain both humoral and cellular immune ...
Scheme of the complement system. The complement system, also known as complement cascade, is a part of the humoral, innate immune system and enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.

Historically, the distinction between the innate and adaptive immune system focused on the innate system’s nonspecific nature and lack of memory. [91] As information has emerged about the functions of NK cells and other ILCs as effectors and orchestrators of the adaptive immune response, this distinction has become less clear.
