I understand the actual knob on a breast for a feeding purpose . Wouldn’t just that be enough ? Why the areola around it especially with a different shade of colour to the rest of the breast ?
In: Biology
“Areolae: The areola is the circular darker-colored area of skin surrounding your nipple. Areolae have glands called Montgomery’s glands that secrete a lubricating oil. This oil protects your nipple and skin from chafing during breastfeeding.”
