Accepted Answer

Hi, everyone. Welcome back. The next problem says, passing maternal antibodies through the newborn through breastfeeding is an example of which type of immunity. A active immunity. B passive immunity, C innate immunity or D induced immunity. So let's think about what's happening in this process. You have a natural process. So it's not being done as a medical treatment. It's just feeding the baby. So a natural process and you have antibodies passing that have been produced by the mother's immune system passing directly to the infant. They can then have immune activity in the infant, but the infant hasn't generated its own antibodies to receive them from an external source. So with that in mind, let's look at our answer choices. Choice. A says active immunity. Well, active immunity is when the body has generated its own immune response, made its own antibodies. So that's not the case with this example. So active immunity will not be our correct answer. Note that that is regardless of whether this is a naturally acquired or artificially acquired immunity, it can be naturally acquired through exposure to a pathogen or artificially acquired through a vaccine. But the key part with active is that the body has made antibodies. Then Choice B says passive immunity and that is what we have here. Passive immunity means the antibodies have been received from an external source. In this case, from the mother, again, passive can be artificially induced as when antibodies are given as a medical treatment, treatment for rabies, antivenom treatment after a snake bite or it can be given as a natural process. A acquired from the mother in breastfeeding, acquired from the mother during pregnancy when antibodies cross the placenta. So choice B is a correct description of what's happening here. Since the infant is not generating its own antibodies just to be thorough. We'll look at our other choices. Choice C innate immunity. This is the whole bunch of natural defenses. The body has to pathogens that are not specific to individual pathogens. So no antibodies evolved or excuse me, no antibodies involved not evolved and requires no prior exposure to a pathogen pathogen invades the body has multiple different ways of defending itself. Ultimately, you'll have this immune response that's specific involving things like antibodies. But you also have this innate immunity that acts immediately non-specific attacks, whatever comes in things like barrier defenses like the skin, preventing things from coming in inflammation, phagocytes that come and engulf foreign bodies. All these things that are innate and non-specific. But this is the passage of antibodies. The antibodies are specific to certain pathogens. So choice C is not the correct example. In addition, it's not the infant's own innate immunity. It's being given from the mother and then choice D induced immunity. This word induced implies that there's a purposeful medical treatment to cause the body to raise an immune response as happens in vaccination or by providing immunity from administered antibodies such as giving antivenom or anti rabies serum. So induced does not fit our example here again, because this is not something being done on purpose as a medical treatment. This is just part of the natural process of breastfeeding a baby and it happens in the course of that natural process. So once again, the process of passing maternal antibodies to the newborn through breastfeeding is an example of choice b passive immunity. See you in the next video.
