Lymph is a fluid that filters between the cells of tissue and then drains into its own set of transport channels. Lymph fluid may carry infectious organisms, toxins or cancerous cells. The channels that carry the lymph fluid are referred to as lymphatics. These lymphatics usually travel near or with the vascular supply of a tissue. Small lymphatics drain into larger lymphatics and eventually all the lymphatic fluid empties into one of the large veins in the thoracic cavity. Along the course of these lymphatic channels are soft tissue structures called lymph glands or nodes. The lymph glands act as filters to remove harmful substances from the lymph fluid. 淋巴是在组织间进行过滤的液体, 它流入自己的输送渠道. 淋巴液载送感染性有机物, 毒素和癌细胞. 载送淋巴液的渠道称为淋巴管。 这些(zhèxiē)淋巴管通常在组织周围流动并且将组织维管联结。 小的淋巴管流入大的淋巴管， 并且最终所有的淋巴液流入胸腔的某个大血管。 在这些(zhèxiē)淋巴管道的路程中有一些软组织称为淋巴腺或淋巴结。 这些(zhèxiē)淋巴结象过滤器一样过滤淋巴液中的有害物质。

The majority of the lymphatic fluid from a breast drains to the ipsilateral axilla. The axilla is rich in both lymphatic channels and lymph nodes. A small portion of the lymphatic drainage from the inferomedial breast parenchyma will drain to the lymphatic system associated with the internal thoracic vessels. 乳腺的大部分(bù fen)淋巴液流入腋窝淋巴。 腋窝富含淋巴管和淋巴结。小部分(bù fen)乳腺内下侧淋巴液引流入胸内脉管的淋巴系统。

For convention the axillary lymph nodes are divided into three groups:
or level 1(inferior to pectoralis minor attachment)第一站淋巴结（胸小肌下）
2. Central or level 2(posterior to pectoralis minor attachment)第二站淋巴结（胸小肌后）
3. Apical or level 3(superio
