Immune System: Innate and adaptive immunity explained

The immune system (or immunity) can be divided into two types - innate and adaptive immunity. This video has an immune system animation. The innate immune system consists of defenses against infection that are activated instantly as a pathogen attacks. Adaptive immunity (or acquired immunity) is a subsystem of the immune system that contains highly specialised systemic cells and processes that kill pathogens and prevent their growth in the body. Innate vs adaptive immunity: it’s important to realize that innate and adaptive immunity are different. Their differences are explained in the video in layman terms.

Our immune system is a fascinating entity, that functions in quite a unique and efficient manner. Comprising of various types of cells, it is prepared for any kind of breach in the fortress of our body, and is equipped to fight off a staggering number of intruders.

Each cell if the immune system carries out various roles, depending on the kind of threat the body is facing. However, they have certain basic roles which have been explained here.
