Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland.When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...

This is deposited on the wool of the sheep and is attached with a glue-like material. The larva immediately hardens and becomes a darker color.
