The azygos vein transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava.. It is formed by the union of the ascending lumbar veins with the right subcostal veins at the level of the 12th thoracic vertebra, ascending to the right of the descending aorta and thoracic duct, passing behind the right crus of diaphragm, anterior to the vertebral ...
The periaortic lymph node group is divided into three subgroups: preaortic, paraaortic, and retroaortic: The preaortic group drains the gastrointestinal viscera. They can be subdivided into three groups: the celiac nodes, the superior mesenteric nodes, and the inferior mesenteric nodes.
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 ...
Lymphadenopathy or adenopathy is a disease of the lymph nodes, in which they are abnormal in size or consistency.Lymphadenopathy of an inflammatory type (the most common type) is lymphadenitis, [1] producing swollen or enlarged lymph nodes.
The retroaortic lymph nodes (or postaortic lymph nodes) are placed below the cisterna chyli, on the bodies of the third and fourth lumbar vertebrae.. They receive lymphatic trunks from the lateral and preaortic glands, while their efferents end in the cisterna chyli.
A lymph node, or lymph gland, [1] is a kidney-shaped organ of the lymphatic system and the adaptive immune system.A large number of lymph nodes are linked throughout the body by the lymphatic vessels.
The superior diaphragmatic lymph nodes lie on the thoracic aspect of the diaphragm, and consist of three sets – anterior, middle, and posterior.. The anterior set comprises (a) two or three small nodes behind the base of the xiphoid process, which receive afferents from the convex surface of the liver, and (b) one or two nodes on either side near the junction of the seventh rib with its ...
The retroperitoneal space (retroperitoneum) is the anatomical space (sometimes a potential space) behind (retro) the peritoneum.It has no specific delineating anatomical structures.
