Question

___ describes the secretion of milk from the mammary glands.

Answer 1

Lactation, secretion and yielding of milk are done by females after giving birth.
The milk is produced by the mammary glands, which are contained within the breasts.
In most species, milk comes out of the mother's nipples; however, the monotremes, egg-laying mammals, lack nipples and release milk through ducts in the abdomen.
