Answer 1

Answer: (B)

• A functional mammary gland is characteristic of all female mammals.
• The mammary glands are paired structures (breasts) that contain glandular tissue and variable amount of fat.
• 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 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 which is connected to lactiferous ducts through which milk is sucked out
