-pericardial sac and heart
Superior mediastinum contains:
- aortic arch and its 3 branches
-trachea
-espohagus - superior vena cava
-brachiocephalic veins
-phrenic and vagus nerves
inferior and posterior mediastinum contains:
- thoracic of descending aorta
-azygos veins
-thoracic duct
-esophagus/ vagus/phrenic
Where does the Azygos vein drain to?
SVC
Hemiazygos is found?
Hemiazygos accessory n?
L. lower intercostal
L. upper costal
Pathway of lymphatic drainage:
Lymphatic
capillaries–> vessels (travel thru nodes)–> trunks–>ducts–> VENOUS BLOOD
where are lymph derived from
they are collection of interstitial fluid
What are the three main functions of lymphatic system?
-return excess body fluid into the blood stream which supplements the cells that need them
-transports lipids
-carry out immune system
thoracic ducts (LEFT) is where ?
-receives lymph from areas below the diaphragm (LEFT)
Where does the thoracic duct lymph empty into?
right lymphatic duct
-r subclavian and r internal jugular vein (according to side)
Where does the thoracic duct found in the vertebrae?
T4-T6
what consists of the lymphatic trunks?
-broncho mediastinal
-subclavian
-jugular
What is the Lymphatic pathway drainage?
-capillaries–> vessels (thru nodes)–> trunks–> ducts–> venous blood
