"The arterial supply originates from the anterior intercostal branches of the internal thoracic arteries; lateral thoracic artery; and thoracodorsal arteries. The venous vessels parallel the arteries. The axillary nodes are the apical axillary nodes, the lateral group and the anterior group. 75% of the lymph is drained through the axillary lymph nodes located near the armpit. The rest of the drainage leaves through infroclavicular, pectoral, or parasternal nodes." You guys hot yet?
