What causes the alveolar cells to begin to release milk during Lactogenesis 2?

  1. Increased estrogen levels

  2. Placenta release

  3. Increase in alveoli

  4. Drop in progesterone levels

The correct answer is: Drop in progesterone levels

During lactogenesis 2, the hormone progesterone decreases significantly as the placenta is removed after childbirth. This hormonal change signals the alveolar cells in the breast to begin producing and releasing milk. Therefore, the drop in progesterone levels is the primary cause for the release of milk during lactogenesis 2. Option A is incorrect because estrogen levels actually decrease during this stage. Option B is incorrect because the placenta is already removed at this point. Option C is incorrect because the increase in alveoli occurs earlier in pregnancy to prepare for milk production.
