Lymph 

 Capillaries 



Thoracic Duct < 



Origin in lymph spaces. 



One coat of endothelium — dentated. 



Start as microscopic hanph capillaries, 

 unite to form lymphatics. Compar- 

 able to formation of veins. 

 Lymphatics — three coats — numerous valves. 



15 to 18 in. long. Size of goose-quill. 



In front of vertebra from 2d lumbar to 

 7th cervical. 



Has three coats — numerous valves. 



Dilatation at lower portion called chyle 

 cistern. 



Receives lymph from left side of head, 

 neck, and chest, left arm, all of abdo- 

 men, and both lower limbs. Receives 

 chyle from lacteals. 



Pours Ij-mph and chyle into left innomi- 

 nate vein. 

 j 1 to 1| in. long. 



j Receives lymph from right side of head, 

 I neck, and chest, also right arm. 



Pours l3^nph into right innominate vein. 



Deep — accompanj'- large blood-vessels. 



Superficial — distributed through the 

 subcutaneous areolar tissue. 



L5Tnphatics of the intestines. 



Many originate in ^^lli of small intestine. 



Contain ( ^"^^"S digestion — chyle. 

 I During fasting — lymph. 

 Absorb fatty substances. 

 ) Expanded IjTiiph spaces. 

 j Communicate by means of stomata with 

 [ other IjTTiph spaces. 

 Function — Drain off IjTnph from all parts of the body 

 and return it to the innominate veins. 



Right Lym- 

 phatic Duct 



Classification
