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

Thoracic duct 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

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

DRAINAGE PATTERN
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
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
