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 ...
[5] [6] Commonly, the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. [7] In a healthy heart, blood flows one way through the heart due to heart valves, which prevent backflow. [4] The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of ...
The crux cordis or crux of the heart (from Latin "crux" meaning "cross") is the area on the lower back side of the heart where the coronary sulcus (the groove separating the atria from the ventricles) and the posterior interventricular sulcus (the groove separating the left from the right ventricle) meet.

Superficial anatomy of female and male human body Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of superficial anatomy Surface anatomy , or superficial anatomy, is important in human anatomy being the study of anatomical landmarks that can be readily identified from the ...
Electrodes can be inserted into and through the coronary sinus to study the electrophysiology of the heart. This includes for a coronary sinus electrogram. [5] The coronary sinus connects directly with the right atrium. It will dilate as a result of any condition that causes elevated right atrial pressure, such as pulmonary hypertension. [7]
English: Heart diagram with labels in English. Blue components indicate de-oxygenated blood pathways and red components indicate oxygenated blood pathways. [1] [2]
For the more particular articles on heart string and ventricle, the diagram is somewhat helpful as they lack a diagram. But I think for those articles, this drawing is overkill, labeling every part of the heart, rather than the few relevant to that smaller topic.TCO (Reviews needed) 06:53, 1 January 2012 (UTC)
