Blood Circulation And Formation of Milk

Anatomy of Mammary Gland

Milk Biosynthesis

Milk is synthesized & produced in the mammary glands. Within the mammary gland is the milk manufacturing unit, the Alveolus. It contains a single layer of epithelial secretory cells circling a central storage area called the Lumen, which is connected to a duct system. The secretory cells are further surrounded by a layer of Myoepithelial cells and blood capillaries. The raw materials for milk production transported through the bloodstream to the secretory cells. It takes 400 to 800 Liters of blood to deliver components for 1 Liter of milk.

William Harvey born 1578 was an English physician and the first known physician to describe completely, and in detail, the blood circulation and properties of blood being pumped to the
