So these seven cells we just described are the major seven cells that are nonspecific and which are part of the innate immune system. Two of these cells are usually found within our skin tissue. We have the mast cell and the dendritic cell. But it's the dendritic cell that moves into our blood and carries the antigens into the adaptive immune system of our body the white blood cells found in our lymph nodes and in our lymph system. So let's move on to our adaptive immune system. So we have two types of cells.
