FORMATION AND TRANSPORT OF TISSUE FLUID

LYMPH TRUNKS right and left jugular trunks right and left subclavian trunks right and left bronchomediastinal trunks right and left lumbar trunks intestinal trunk

LYMPHATIC DUCTS Right lymphatic duct 24-5 Right lymphatic duct Formed by union of right jugular, subclavian, and bronchomediastinal trunks Ends by entering the right venous angle

Thoracic duct LYMPHATIC DUCTS Begins in front of L2 as a dilated sac, the cisterna chyli, ( 38-45 cm ) formed by left and right lumbar trunks and intestinal trunk

THORACIC DUCT….. arches forwards and descends to enter the left venous angle before termination, it receives the left jugular, Subclavian and broncho- mediastinal trunk

DRAINAGE PATTERN RIGHT LYMPHATIC DUCT ( 1.2 cm )Receives lymph from right half of head, neck, thorax and right upper limb, right lung, right side of heart, right surface of liver THORACIC DUCT - Drains lymph from lower limbs, pelvic cavity, abdominal cavity, left side of thorax, and left side of the head, neck and left upper limb
