What type of tissue is primarily responsible for milk production in the breast?

The type of tissue primarily responsible for milk production in the breast is glandular tissue. This tissue is composed of specialized epithelial cells that form the ducts and lobules of the mammary glands. These cells perform the function of secreting milk during lactation, which is primarily regulated by hormonal changes that occur during pregnancy and after childbirth.

Glandular tissue in the breasts is organized into lobes, which further contain smaller lobules where the milk-secreting cells, known as alveoli, are located. When stimulated by hormones such as prolactin, these cells produce milk, which is then transported through the ductal system to the nipple for breastfeeding. This structure and function highlight the essential role of glandular tissue in lactation, distinguishing it from other tissue types such as fibrous, adipose, or epithelial tissues, which have different structures and functions in the body.
