Now, we also have these ligaments of Cooper. And the ligaments of Cooper are essentially these fibers, bands of connective tissue that connect the entire breast to the skin, that encloses the breast. And we also have this adipose tissue, the fat tissue shown in orange. And the fat tissue basically determines the size of the breast and it also determines the softness of the breast. So the more fat we have in the breast, the larger the breasts are. Now we also have these blood vessels and the blood vessels consist of arteries as well as of veins.
