Vellus hair is present on the chest, back and cheeks to mainly regulate temperature. The glandular tissue, called mammary glands of the breast, is divided by fibrous bands of connective tissue into 15 to 20 radially arranged sections known as lobes. Each of these lobes is further divided into several smaller lobules. Each lobule consists of grape like clusters of sac like structures called acini. These acini are lined by milk producing cuboidal cells and are capable of expansion to store the produced milk. Breasts have three types of tissues - glandular, fatty and fibrous connective tissue. The fatty tissue surround the glandular tissue and the fibrous connective tissue supports this glandular structure. Breast development and lactation is regulated by hormones like oxytocin, prolactin, estrogen and progesterone.
