What is the function of the lactiferous sinus in the human body?

The lactiferous sinus plays an essential role in lactation by serving as a storage area for milk produced by the mammary glands. It is located at the end of the lactiferous duct and acts as a reservoir, allowing milk to accumulate before being delivered to the nipple during breastfeeding. This functionality is crucial for efficient breastfeeding, as it ensures that milk is readily available when the infant latches on and begins to feed.

While other functions such as hormone production, nutrient absorption, and toxin filtration are important in various bodily systems, they are not associated with the role of the lactiferous sinus. The primary purpose of the lactiferous sinus revolves specifically around the storage and transport of milk, aligning directly with its anatomical and physiological role in the breastfeeding process.
