Answer 1

Answer:

A. alveoli

• 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 mammary 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 duct through which milk is sucked out.
