The periaortic lymph nodes (also known as lumbar) are a group of lymph nodes that lie in front of the lumbar vertebrae near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. The periaortic lymph nodes are different from the paraaortic lymph nodes. The periaortic group is the general group ...
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 inferior mesenteric lymph nodes have a subgroup of pararectal lymph nodes. The preaortic lymph nodes receive a few vessels from the lateral aortic lymph nodes , but their principal afferents are derived from the organs supplied by the three arteries with which they are associated–the celiac , superior and inferior mesenteric arteries .
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century. [1] [2] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following on a single grid: Blood pressure. Aortic ...
Most are located above the aortic arch, [2] while some are located on the posterior side of the aortic arch between it and the pulmonary artery below. [3] They consist of glomus cells and sustentacular cells. [1] Some sources equate the "aortic bodies" and "paraaortic bodies", while other sources explicitly distinguish between the two.
