What is Lactogenesis 4 also known as?

1. Involution

2. The resupply of mature milk

3. Milk production initiation

4. Emptying of the alveolus

The correct answer is: Involution

Lactogenesis 4, also known as involution, is the process of the breast returning to its pre-pregnancy state after lactation. This is not to be confused with lactogenesis 1, 2, or 3, which refer to the initial production of milk. Option B, the resupply of mature milk, is incorrect because it does not specifically refer to Lactogenesis 4. Option C, milk production initiation, is incorrect because it refers to the beginning stages of milk production, not the end. And option D, emptying of the alveolus, is incorrect because it is referring to the physical act of milk being released, not the overall process of Lactogenesis 4.
