A functional mammary gland is characteristic of all female $\underline{A}$ 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 $\underline{B}$ . The cells of $\underline{C}$ 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 $\underline{D}$ duct. Several $\underline{E}$ ducts join to form a wider mammary ampulla which is connected to $\underline{F}$ duct through which milk is sucked out.
