What are the lines of the defense of the immune system?

The

line of defense of the immune system consists of three main components: congenital, adaptive and acquired immune systems. Each system is created separately and acts as an independent defense system and a symbiotic system operating in conjunction with others. The systems are layered in such a way that if the threats slip around one line of defense, they will start another in a row to respond. Of the three components forming a line of defense of the immune system, each serving either in defensive or offensive capacity against pathogens such as viruses, bacteria and other foreign bodies.

Every human being is born with a congenital immune system. As an integral part of the lines of the defense of the immune system, congenital immunity is also known as non -specific immunity, due to its more passive, more generalized role in the immune system. Physical barriers such as leather and mucous membranes are a primary part of the innate immune system. This is the first Lines of Defense, prevents pathogens to the body. Congenital immunity isconsidered a defensive member of the immune system and uses tools such as inflammation to signal other immuno -related systems to mount the answer.

Next in a series of body defense against pathogens is an adaptive immune system. If bacteria, viruses or other foreign body got through the physical barriers of the body, some cells known as a natural killer or t cells directly attack pathogens. When the body indicates the presence of toxins, bacteria, damaged body cells, viruses or other foreign molecules, killer cells and their associated auxiliary cells, they seek and destroy the threat before having a chance to create disease, disease or abnormal growth. Adaptive immunity is considered to be an offensive component in the lines of the immune system defense, and its name is accepted from the possibility of appropriation to adapt in response to different threats.

acquired immunity involves numerous individualfactors. Immunization and antibodies created after a previous pathogen exposure fall under the acquired immunity. Some types of immunity obtained are temporary or passive considered both the offensive and defensive component of the human immune system. For example, newborns borrow immunity from their mothers, first through the placenta during pregnancy and after birth through a colostrum in breast milk. Later, because the child ripens and experiences exposure to certain pathogens, the adaptive immune system helps the acquired immune system by creating memory cells or antibodies. This allows the acquired immune system to set permanent defense against certain types of threats.
