The gastric lymph nodes are lymph nodes (also known as lymph glands) which drain the stomach and consist of two sets, superior and inferior: The superior gastric lymph nodes (Latin: lymphoglandulæ gastricæ superiores) accompany the left gastric artery and are divisible into three groups: Upper, on the stem of the artery;
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 carries unfiltered lymph into the node. In doing this they lose all their coats except their endothelial lining, which is continuous with a layer of similar cells lining the lymph paths. Afferent lymphatic vessels are only found in lymph nodes. This is in contrast to efferent lymphatic vessel which are also found in the thymus and spleen.
Lymphatic vessels develop from lymph sacs that arise from developing veins, which are derived from mesoderm. The first lymph sacs to appear are the paired jugular lymph sacs at the junction of the internal jugular and subclavian veins. From the jugular lymph sacs, lymphatic capillary plexuses spread to the thorax, upper limbs, neck, and head.
Proliferation of cells within a lymph node will make the node expand. Lymph is present throughout the body, and circulates through lymphatic vessels. These drain into and from lymph nodes – afferent vessels drain into nodes, and efferent vessels from nodes. When lymph fluid enters a node, it drains into the node just beneath the capsule in a ...
Visceral nodes of the abdominal cavity. The hepatic lymph nodes consist of the following groups: (a) hepatic, on the stem of the hepatic artery, and extending upward along the common bile duct, between the two layers of the lesser omentum, as far as the porta hepatis; the cystic gland, a member of this group, is placed near the neck of the gall-bladder;
The villi contain a lacteal, a vessel connected to the lymph system that aids in the removal of lipids and tissue fluids. Microvilli are present on the epithelium of a villus and further increase the surface area over which absorption can take place.
The intestinal trunk receives the lymph from the stomach and intestine, from the pancreas and spleen, and from the lower and front part of the liver, and empties lymph into the cisterna chyli, which in turn drains into the thoracic duct.
