Mammary gland
A mammary gland is an organ in female mammals that produces milk to feed young offspring. Mammals get their name from the word ""mammary."" In humans, the mammary glands are situated in the breasts. In ruminants such as cows, goats, and deer, the mammary glands are contained in the udders. The mammary glands of mammals other than primates, such as dogs and cats, are sometimes called dugs.
