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 ...
Some leukocytes (white blood cells) act like independent, single-celled organisms and are the second arm of the innate immune system. The innate leukocytes include the "professional" phagocytes (macrophages, neutrophils, and dendritic cells). These cells identify and eliminate pathogens, either by attacking larger pathogens through contact or ...
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".
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.
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.

Also, this is when you build your innate immune system and convert short-term memory into long-term memory. You also wake up with more energy and vibrance,” Dr. Rocco says.
Phagocytes form part of the innate immune system, which animals, including humans, are born with. Innate immunity is very effective but non-specific in that it does not discriminate between different sorts of invaders. On the other hand, the adaptive immune system of jawed vertebrates—the basis of acquired immunity—is highly specialized and ...
