Mammary glands blood supply

Answer 1

● The thoracic and cranial abdominal mammary complexes receive blood from the
mammary branches of the cranial superficial epigastric artery

● Ventral intercostal branches of the internal thoracic artery may also contribute to
the thoracic glands
● The caudal abdominal and inguinal mammary complexes are supplied by mammary branches of the
CAUDAL SUPERFICIAL EPIGASTRIC ARTERY (ex. A. Pudenda externa)

VEINS

cranial epigastric —> internal thoracic

● Abdominal and inguinal mammary complexes drain into caudal superficial
epigastric —> external pudenda
