Lymphatic System Flashcards
Lymphatic flow patterns?
6
Capillaries (nodes are in the capillaries) The collecting vessels Lymph trunks Lymphatic ducts Subclavian vein Superior Vena Cava
Where is there no lymphatic drainage?
3
CNS
Bone marrow
Anywhere there is no vasculature(blood vessels)
Where does the thoracic duct supply lymph to?
Left and inferior portions of the body
The cisterna chyli collects from the lower portions of the body and flows into the thoracic duct
-left jugular vein
-left subclavian trunk
-thoracic duct entering left subclavian vein
-left bronchomediastinal trunk
Where does the right lymphatic duct supply lymph to?
Upper right portion of the body
- right jugular trunk
- right subclavian trunk
- right lymphatic trunk entering the subclavian vein
- right bronchomediastinal trunk
Lymph nodes in the head and neck?
9
Submental Pre auricular Post auricular Occipital Supraclavilcular infraclavicular Anterior cervical Posterior cervical Deep cervical
Axillary lymph nodes?
5
Medial Lateral Anterior Posterior Axillary nodes
Inguinal lymph nodes?
2
Superficial and deep inguinal arteries
Abdominal and thoracic nodes?
They are in bundles along the vena cava and pulmonary hilum
What are peyer’s patches and where are they located?
located in the wall of the ileum of the small intestine
Contains microphages that capture and destroy bacteria thereby preventing microbes from breaching the intestinal wall

Fat transport from intestine
Purify blood
What is the difference between nodes and nodules?
Nodules don’t have a tough outer layer
Nodes have a tough outer layer and are found all over the body
Where does lymph from the lower body collect at?
Cisternae chyli
If you are taking out the medialstinal node where would you enter the body?
Go through the right side to miss all the great vessels
