Osmosis video - Mammary gland histology

Mammary glands are organs that produce milk for nursing infants. The mammary gland is composed of lobules, which are clusters of cells that produce milk, and ducts, which are the channels that transport the milk to the nipples. The lobules and ducts are surrounded by a layer of adipose tissue, which provides insulation and helps protect the delicate mammary gland tissue.

The mammary gland is supplied with blood vessels and lymphatic vessels, which provide nutrients and remove waste products from the gland. The nipple is supplied with nerves that provide sensation and facilitate nursing.
