The immune system is nothing but the human body’s defense mechanism that helps us in protecting from many different pathogens, bacteria, fungi, viruses, and diseases. The immune system is a system of cells that are spread out through out our body to guard our body against any pathogens or organisms that are not good for the human body.

The immune system detects any unwanted outsiders within our body and attacks them with the aim of keeping us safe and healthy. 

So, whenever our immune system detects something that is harmful to use, it gets activated. This is usually known as an antigen. There are different antigens and once this is identified our immune system generates an immune response.

In the immune response, the signal between different cells of the immune system. There are different types of the immune responses, innate and adaptive.

An innate response is something that happens immediately and is also non-specific. They are the first responders, and there are many types of innate immune cells, like macrophages, monocytes, neutrophils, dendritic cells, and eosinophils (1).

The innate immune cells activate the adaptive response. When an innate immune response takes place, it can cause inflammation and thus releases cytokines within the body. 

On the other hand, the adaptive immune response is much more specific, and it is generally related to memory. This means that the adaptive response, when exposed to an antigen, learns how to respond to it in the future again. The adaptive immune response includes B cells and T cells (2).
