Fill in the blank(s) with correct word
Lactiferous ducts
Rationale: The glandular tissue of the breast contains 15 to 20 lobes radiating from the nipple, and these are composed of lobules. Within each lobule are clusters of alveoli that produce milk and colostrum. Each lobe empties into a lactiferous duct. The 15 to 20 ducts form a collecting duct system converging toward the nipple. There, the ducts form ampullae, or lactiferous sinuses, behind the nipple, which are reservoirs for storing milk and colostrum.
