In humans, the cisterna chyli is located posterior to the abdominal aorta on the anterior aspect of the bodies of the first and second lumbar vertebrae (L1 and L2). There it forms the beginning of the primary lymph vessel, the thoracic duct, which transports lymph and chyle from the abdomen via the aortic opening of the diaphragm up to the junction of left subclavian vein and internal jugular ...
In human anatomy, the thoracic duct (also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne's canal) is the larger of the two lymph ducts of the lymphatic system (the other being the right lymphatic duct). [1] The thoracic duct usually begins from the upper aspect of the cisterna chyli, passing out of the ...
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] also, in some individuals, the lower lobe of the left lung. [5] All other ...
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
The efferents of the glands in the lower four or five spaces unite to form a trunk, which descends and opens either into the cisterna chyli or into the commencement of the thoracic duct. The efferents of the glands in the upper spaces of the left side end in the thoracic duct; those of the corresponding right spaces, in the right lymphatic duct.
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 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 lymph glands of the thorax may be divided into parietal and visceral — the former being situated in the thoracic wall, the latter in relation to the viscera. References [ edit ]
