What is the primary function of milk ducts during lactation?

• A. They create milk
• B. They transport milk from glands to the nipple
• C. They store milk
• D. They regulate milk temperature

Answer: (B)

The primary function of milk ducts during lactation is to transport milk from the glands, where it is produced, to the nipple, allowing for the transfer of milk to the infant during breastfeeding. The ducts are essential in ensuring that milk flows effectively from the lactating mammary glands to the nipple, where it can be accessed by the baby. This transportation is crucial for successful breastfeeding, as it enables the infant to receive the necessary nutrients and hydration that breast milk provides. The structure and function of milk ducts are designed to facilitate this process, making them integral to lactation.
