Identify the correct path of milk secretion by the mammary glands:

Step-by-step solution

The glandular tissue of each breast is divided into 15-20 mammary lobes containing clusters of cells called alveoli. The cells of alveoli secrete milk, which is stored in the cavities (lumens) of the alveoli. The alveoli open into mammary tubules. The tubules of each lobe join to form a mammary duct. Several mammary ducts join to form a wider mammary ampulla. The mammary ampulla is connected to the lactiferous duct through which milk is sucked out. The correct sequence of milk secretion is: Alveoli mammary tubules
