Chapter 12 The Lymphatic System
THE CIRCULATORY SYSTEM
2
general introduction
The lymphatic system
consists of lymphatic
vessels and various
lymphatic tissues and
organs
3
•The lymphatic vessels and the sinuses of the lymph nodes contain tissue fluid , which is called lymph.
lymphatic capillary
histiocyte
tissue fluid
blood capillary( vein)blood capillary
( artery)
4
lymphatic vessel
The composition and construction features of lymphatic system
lymphatic capillary:the initiation is dead end, the endothelium is thin and intercellular spaces are wide 。
histiocyte
endothelial cell
The lymphatic capillaries do not present in epithelium , cornea, lens, cartilage, brain and spinal cord
5
lymphatic vessel
• deep lymphatic vessel (located in deep fascia)
The stems go in company with deep vein
• superficial lymphatic vessel (located in superficial fascia) The stems go in company with cutaneous vein
there are affluent communications between the superficial and deep lymphatic vessels

lymphatic duct
The lymphatic capillaries join to fo
rm progressively larger vessels, unt
il finally the thoracic duct and the r
ight lymphatic duct
the thoracic duct return to left ve
nous angle, and the right lymphatic
duct return to right venous angle,
a few lymphatic vessels return to
renal vein 、 superarenal vein and
inferior vena cava.
8
lymphatic tissues
diffuse lymphoid tissue They main located in the lamina propria mucosae of digestive tract and respiratory tract.
lymphatic nodule they include the solitary and aggregated lymphatic follicles which present in the submucosa of the small intestine , and lymphatic nodules which present in the wall of vermiform appendix.
lymph nodes of organs located in abdominal cavity Lymph nodes accompany celiac truck and its branches left and right gastric lymph nodes left and right gastroomental lymph nodes pyloric lymph nodes hepatic lymph nodes pancreatic lymph nodes splenic lymph nodes →celiac lymph node
23
Lymph nodes accompany superior mesenteric arteries and their branches
Lymphatic Drainage of some organslymphatic drainage of the lung Superficial lymphatic vessels of the lung are located in the deep face of the visceral pleuraDeep lymphatic vessels of the lung flow to the pulmonary lymph nodes and the bronchopulmonary lymph nodes Communication present between the superficial and deep lymphatic vessels 。 pulmonary lymph node →bronchopulmonary lymph nodes → tracheobronchial lymph node and paratracheal lymph node lymphatic vessels from the lower lobe flow to the lymph nodes which located in pulmonary ligament Lymphatic vessels from the lower part of the superior lobe of the left lung and some lymphatic vessels from the lower lobe →upper group of the right tracheobronchial lymph node and right paratracheal lymph node
25
Lymphatic Drainage of the esophagusLymph of cervical part esophagus→paratracheal lymph node and inferior deep lateral cervical lymph node 。Lymph of thoracic part esophagus→posterior mediastinal lymph node ,lymph of the superior segment of thoracic part→paratracheal lymph nodes and tracheobronchial lymph nodelymph of the inferior segment of thoracic part →left gastric lymph nodelymphatic vessels of epicardia→left gastric lymph nodeA few of lymphatic vessels of esophagus→thoracic duct
26
Lymphatic Drainage of the rectum The lymphatic vessels of the anal canal above the dentate line :accompany the superior rectal artery ,then ascending to enter the superior rectal lymph nodes ;accompany the inferior rectal aryery,then enter the internal iliac lymph nodes accompany the anal artery and then follow the pudental artery to enter the internal iliac lymph nodes, part of lymphatic vessles follow the Vessles of sacro-lateral , then enter the sacral lymph nodes.
The lymphatic vessels of the anal canal under the dentate line enter the superficial inguinal lymph nodes.
27
Lymphatic drainage of the uterus lymphatic vessels located in the superior aspect of fundus of uterus and body of uterus: follow the ovarian blood vessels and ascend to terminate mainly in the lumbar lymph nodes. accompany the round ligament , pass the inguinal canal , and reach the superficial inguinal lymph nodes. lymphatic vessels located in inferior part of the uterus and cervical of the uterus : follow blood vessels of the uterus and reach the external and internal iliac lymph nodes ;Pass cardinal ligament of uterus and reach the obturator lymph nodes ; follow the sacrouterine ligament , go backward and reach the sacral lymph nodes.
28
Lymphatic drainage of the breast
The lymph of the breast mainly reach the axillary lymph nodeslymphatic vessels located in lateral and central part of the breast reach the pectoral lymph nodes ; superior lymphatic vessels reach apical lymph nodes and supraclavicular lymph nodes;medial part lymphatic vessels reach parasternal lymph nodes.
29
the spleen
The spleen is the largest lymphatic organ. It functions in storing blood, haematogenesis, disposing effete red cells and immunologic response.
