Now that we discuss the many details of our immune system let's actually connect the dots. Let's describe how the innate immune system interacts with the adaptive immune system and how they work together to actually carry out the function of protecting and defending our healthy cells of the body from different types of pathogenic infections. And let's begin by imagining the following scenario. Let's suppose we have the surface of our skin as shown in the diagram. Then we have the skin tissue and below that we have our blood vessel that carries our blood plasma from this side to this side of our diagram. Now let's imagine that we have some type of cut that is formed on the surface of our skin as shown in this diagram.
