This cell is also capable of binding any antigen nonspecifically. But it takes that antigen and it brings it to the adaptive immune system and we'll see exactly what the interaction is in just a moment. So it's the dendritic cell that connects the innate immune system to our adaptive immune system of our body. Now let's move on to the cells that are found in the blood that are called upon by these chemicals released into our blood in the first place by the mast cell and by other cells of our body. So let's begin with a group of cells known as granulocytes. And these granulocytes are called granulocytes because they have granules.
