Now, another way we pass down or we create passive immunity naturally is via the process of breastfeeding. So the milk that is found in women during the process of breastfeeding contains yet another type of immunoglobulin antibody known as immunoglobulin A. And once our child gains the immunoglobulin A via the milk via the process of breastfeeding, that boosts their immune system because the child's immune system is still developing following childbirth. So this is basically a diagram of flow chart that describes everything we just discussed. It summarizes our results, our discussion. So we have our immune system that is split into two categories.
