THORAX
Important points to make:
There are two terminal branches of the lymphatics drainage system
1. THORACIC DUCT
2. RIGHT LYMPHATIC DUCT
Thoracic duct
Is longer, drains blood from all the body. Drains in between the left subclavian and internal jugular veins.
Right lymphatic duct
Is short, made up of the bronchomediastinal duct, the subclavian duct, the jugular trunk. Drains the right side of the face and chest (and the left inferior lung lobe)
A LOT drains into the right and left bronchomediastinal trunks:
- superficial lung lymphatics
- deep lung lymphatics
- left and right heart lymphatics
- superior diaphragmatic nodes
- parasternal nodes
The axillary nodes do not drain into the bronchiomediastinal trunks, they drain into the subclavian trunks.
