See lessHow does the anatomy of the ribs differ between true, false, and floating ribs?
True ribs articulate directly with the sternum, false ribs indirectly connect to the sternum or other ribs, and floating ribs do not attach to the sternum at all.
True ribs articulate directly with the sternum, false ribs indirectly connect to the sternum or other ribs, and floating ribs do not attach to the sternum at all.
See lessWhat is the role of the thoracic duct in the lymphatic drainage of the thorax?
The thoracic duct collects lymphatic fluid from the lower body, left upper limb, and left side of the head and neck, draining it into the venous system.
