noun, plural: right lymphatic ducts

The lymphatic duct that lies on the right side of the rood of the neck, and drains lymph fluid from the upper right section of the trunk, the right arm, and the ride side of the head and neck


In human lymphatic system, the lymphatics (or lymphatic vessels) are the channels that convey the colorless, alkaline fluid called lymph. The lymphatics include the lymph capillaries (which are the smallest channels of the lymphatic system), the collecting lymph vessels with valves, and the lymphatic ducts, which are the terminal lymphatic vessels that empty to the subclavian veins.

There are two major lymphatic ducts in human lymphatic system. These are the right lymphatic duct and the thoracic duct. The right thoracic duct is about 1.25 cm in length. It is formed through the union of the right jugular lymphatic vessel and the vessels from the lymph nodes of the right upper extremity, thoracic wall, and both lungs.1

The right lymphatic duct drains lymph fluid into the bloodstream from the upper right quadrant of the body via the right bronchomediastinal trunk, the right arm through the right subclavian trunk, and the ride side of the head and neck through the right jugular trunk. In others, it also collects lymph from the left lower lobe of the lung. It usually ends in the right subclavian vein.
