Anatomy Physiology of The Breast
The breast are compound secreting glands, composed mainly of glandular tissues which is arranged in lobes, approxiamately 20 in number. Each lobe is divide into lubues that consist of alveoli and ducts. The alveoli contain acini cells which produce milk and are surrounded by myo-epithelial cells which contact and propel the milk out. The breast are richly supplied with blood. Small lactiferous ducts, carrying milk from alveoli, unite to form langer ductus: one large duct leaves each lobe and widens to form a lactiferous sinus or ampulla which acts as a temporary reservoir for milk. A lactiferous tubule from each sinus emerges on the surface of the nipple. Each of breast functions independently of the other.
