Diagram showing parts of the body that drain into the right lymphatic duct. The right duct drains lymph fluid from: the upper right section of the trunk, (right thoracic cavity, via the right bronchomediastinal trunk) [1] the right arm (via the right subclavian trunk) [1] and right side of the head and neck (via the right jugular trunk) [1]
A lymph duct is a great lymphatic vessel that empties lymph into one of the subclavian veins. There are two lymph ducts in the human body—the right lymphatic duct and the thoracic duct. The right lymphatic duct drains lymph from the right upper limb, right side of thorax and right halves of head and neck.
The left bronchomediastinal lymph trunk often empties into the thoracic duct or directly into the venous angle, where the internal jugular and subclavian veins converge. Similarly, the right trunk may connect to the right lymphatic duct or end at the right venous angle. [2]
The right lymphatic duct drains the right side of the region and the much larger left lymphatic duct, known as the thoracic duct, drains the left side of the body. The ducts empty into the subclavian veins to return to the blood circulation. Lymph is moved through the system by muscle contractions. [9]
The cisterna chyli or receptaculum chyli (chy·li pronounced: ˈkī-ˌlī) is a dilated sac at the lower end of the thoracic duct in most mammals into which lymph from the intestinal trunk and two lumbar lymphatic trunks flow. It receives fatty chyle from the intestines and thus acts as a conduit for the lipid products of digestion. It is the ...
The lymphatic vessels that link the lymph nodes are: The lymphatics of the head, face, neck, and meningeal lymphatic vessels – drain to the deep cervical lymph nodes; The jugular trunk; The subclavian lymph trunk; The thoracic duct; The lymphatics of the upper extremity; The right and left bronchomediastinal lymph trunks; The lymphatics of ...
It in turn drains into one of the two lymph ducts (right lymph duct and the thoracic duct). When an efferent lymph vessel leaves a lymph node, it may carry lymph to another lymph node by becoming its afferent lymph vessel or unite with other efferent vessels to become a lymph trunk. The lymph trunks drain into the lymph ducts, which in turn ...
They receive the lymph from the lower limbs, from the walls and viscera of the pelvis, from the kidneys and suprarenal glands and the deep lymphatics of the greater part of the abdominal wall. Ultimately, the lumbar trunks empty into the cisterna chyli , a dilatation at the beginning of the thoracic duct .
