Question

The nurse is reviewing the role of the mammary glands in the reproductive process with a birth class. What should the nurse tell the class is the name of the ducts in the mammary glands that form a small reservoir for milk?

A) Lactiferous ducts
B) Alveoli
C) Acini
D) Sinuses

Answer 1

The nurse should inform the class that the name of the ducts in the mammary glands that form a small reservoir for milk is D) Sinuses.

Step-by-step explanation:

The lactiferous ducts in the mammary glands form a small reservoir for milk known as lactiferous sinuses or simply sinuses. During lactation, milk is produced by the mammary glands in structures known as alveoli, which are lined with milk-secreting cells called lactocytes. The milk is then secreted into the alveoli and from there, it is squeezed by the contraction of myoepithelial cells into the lactiferous ducts. These ducts lead to the lactiferous sinuses before the milk exits through the nipple pores. The alveoli are part of lobules, which are clusters of alveoli that drain into a common duct and serve as the site where milk accumulates before being transported through the duct system. The correct option that the nurse should tell the class is D) Sinuses.
