Q15. Describe the structure of mammary gland with the help of a neat labeled diagram of the sectional view of mammary gland.

Human female has a pair of mammary glands (breasts) that contain glandular tissues and fatty tissues.
❖ Each glandular tissue is divided into 15-20 mammary lobes and each lobe consists of a group of alveoli.
❖ The alveoli open into mammary tubules.
❖ The mammary tubules of each lobe open into small mammary duct.
❖ Several mammary ducts join to form a wider mammary ampulla that is connected to lactiferous duct just before the nipple through which milk is released.
