Arrange the following events describing the pathway of milk in the human mammary gland in the correct sequential order: (a) Milk enters the mammary tubules (b) Storage of milk in the lumens of alveoli (c) Milk is drawn out through the lactiferous duct (d) Collection of milk in the wider mammary ampulla (e) Tubules join to pass milk into the mammary duct Choose the correct answer from the options given below:

Step-by-step solution

The cells of alveoli secrete milk, which is stored in the cavities (lumens) of 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 sequential order is (b) (a) (e) (d) (c). Answer: (b) (a) (e) (d) (c)
