The breast is located at the front of the chest and is primarily associated with the mammary gland, which is responsible for producing milk. This gland is mainly composed of fat and contains a complex network of branching ducts. These ducts originate from sac-like lobules capable of producing milk in females and lead out of the breast through the nipple.The breast is often considered an organ primarily for milk production. The lobules serve as the milk-producing glands, while the ducts function as channels that transport milk from these glands to the nipple. The nipple can become erect due to cold, breastfeeding, or sexual arousal. The darker pigmented area surrounding the nipple is known as the areola.The lobules and ducts are supported by surrounding fatty tissue and ligaments, with no muscles present within the breast itself. Blood vessels and lymphatics, which are thin channels similar to blood vessels but do not carry blood, are also present. Instead, lymphatics collect and transport tissue fluid back into the bloodstream. This fluid drains through the lymphatics into the lymph nodes located in the underarm (axilla) and behind the chest wall.
