What type of glands in mammals produce milk for nourishing their young?

Mammary glands are specialized exocrine glands that produce milk in mammals, allowing them to nourish their offspring effectively. These glands undergo various changes during pregnancy and lactation, producing a nutrient-rich fluid that provides essential proteins, fats, vitamins, and antibodies that are crucial for the growth and immune support of the young mammal.

In contrast, sebaceous glands secrete an oily substance to lubricate skin and hair, while salivary glands produce saliva to aid in digestion. Endocrine glands, on the other hand, release hormones directly into the bloodstream, playing roles in various bodily functions but are not involved in milk production. Thus, mammary glands are uniquely adapted for the purpose of nurturing young, setting mammals apart in their reproductive strategies.
