Natural Acquired Immunity
Natural immunity is the immune system based on the genetic constitution of certain organisms. A person or an animal is born with one's innate resistance against certain pathogen. At present, all immune systems require contact with antigens, and they acquire immunity accordingly, which is viewed as an outdated concept. There are three possible cases :
1.The antibodies of the parent are transmitted to their fetus through the placenta or colostrum, and the infant is also referred to as a passive immunity.
2.A pathogen that is toxic to other species of animals is harmless to any animal, for example, a human distemper virus does not infect a human.
3.Some may refer to the immunity obtained by the automaticity. This is also referred to as natural acquired immunity. …show more content…
Secondary defenses for natural immunity are played by monocytes, macrophage, and NK cells. Natural killer cells kill infections immediately.
If the body fails to remove all the harmful substances with the natural immunity, the stronger acquired immunity acts as a secondary defense to remove rest of the foreign substances. Exposure to any antigens is induced by specific microbial antigen infections and unique responses to specific antigen cells, thereby giving lifetime immunity to antigens. Lymphocytosis (B cells, T cells) becomes the starting point of acquired immunity. It is divided into cellular mediated immune responses (T cells) or bodily fluids (B cells). It is induced by antigen inflow and is capable of distinguishing specific antigens. As the number of antigen streams increases, the ability to increase the reaction is utilized to develop vaccines. For example, it needs to be infected once in a way to gain immunity to the mumps. It's an immune system that exists only in high
