What is the function of Montgomery's glands located on the areola?

Montgomery's glands, which are small sebaceous glands located on the areola, serve the primary function of providing lubrication. These glands secrete an oily substance that helps to keep the areola and nipple area moisturized, which is particularly important during breastfeeding. The lubrication produced by Montgomery's glands can also provide a protective barrier against bacterial invasion, reducing the risk of infection in this sensitive area.

In addition to lubrication, the secretions can help to create an appealing scent that may aid in attracting the infant to the breast during feeding. This natural oil plays a crucial role in facilitating the breastfeeding process and maintaining the health of the skin in the area.

The other choices highlight functions that are not associated with Montgomery's glands. For instance, while milk production is the primary function of breast tissues and not of the glands on the areola, lymphatic drainage is related to the lymphatic system, which includes different anatomical structures, and blood flow regulation pertains to vascular functions, neither of which pertain to the role of Montgomery's glands.
