 Hey everybody, Dr. O. Real short video, just want to, we've talked about it in other places but just want to highlight prolactin for just a moment so it promotes lactation. That's where the name prolactin comes from. During pregnancy, it's going to contribute to the development of the gland, the mammary gland, the tissue that actually will produce and secrete the milk. So the development of the mammary gland tissue and then the production of milk. Those are the two key functions. As you can see here, you can see milk flowing from these lactiferous ducts and we can cover that separately when we talk about the reproductive system. But for now, just remember the development of the glands that produce the milk and the production of milk. But don't forget that the let down reflex and the ejection of milk from these glands is going to be under the influence of oxytocin. There's an example of two hormones that need each other. So short and sweet, just wanted to highlight in one place on its own. That's prolactin. I hope this helps. Have a wonderful day. Be blessed.
