Lateral thoracic artery and the axillary artery, with its other branches - anterior view of right upper limb and thorax.
In human anatomy, the lateral thoracic artery, also a. thoracalis lateralis and external mammary artery, is a blood vessel that supplies oxygenated blood to the lateral structures of the thorax and breast. It originates from the axillary artery and follows the lower border of the Pectoralis minor muscle to the side of the chest, supplies the Serratus anterior muscle and the Pectoralis major muscle, and sends branches across the axilla to the axillary glands and Subscapularis muscle; it anastomoses with the internal thoracic artery, subscapular, and intercostal arteries, and with the pectoral branch of the thoracoacromial artery. In the female it supplies an external mammary branch which turns round the free edge of the Pectoralis major and supplies the mamma.

The axillary artery and vein, with the brachial plexus of nerves, extend obliquely along the lateral boundary of the axilla, from its apex to its base, and are placed much nearer to the anterior than to the posterior wall, the vein lying to the thoracic side of the artery and partially concealing it.
At the forepart of the axilla, in contact with the Pectorales, are the thoracic branches of the axillary artery, and along the lower margin of the Pectoralis minor the lateralthoracicartery extends to the side of the chest.
