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 ...
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 .

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.

The section shows: 1) the opened ventricles contracting once per heartbeat—that is, once per each cardiac cycle; 2) the (partly obscured) mitral valve of the left heart; 3) the tricuspid and pulmonary valves of the right heart—note these paired valves open and close oppositely. + (The aortic valve of the left heart is located below the ...
Graphical representation of the electrical conduction system of the heart that maintains the heart rate in the cardiac cycle. Electrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract. Then the signals travel to the atrioventricular node (AV node), which is located in the interatrial septum.
