The great cardiac vein collects blood from the anterior surface of the heart.
Oct 20, 2024 · The epithelial tissue secretes the lubricating serous fluid that fills the pericardial cavity and reduces friction as the heart contracts. Adipose connective tissue can also be found in the epicardium, particularly in the areas where blood vessels run along the heart's surface.
Jul 13, 2023 · The blood supply to the heart arises from the left and right semilunar cusps of the aortic valve (respectively): The left coronary artery gives rise to the anterior interventricular (left anterior descending) and the left circumflex arteries.
Nov 12, 2024 · The great cardiac vein is one of the primary veins responsible for draining deoxygenated blood from the heart muscle (myocardium). It originates near the apex of the heart and travels along the anterior interventricular sulcus, running parallel to the left anterior descending artery (LAD).
Nov 10, 2024 · The heart is a four-chambered muscular organ with a complex structure that allows it to efficiently pump blood throughout the body. It is divided into two halves—the right and left sides—each responsible for different aspects of circulation. The heart consists of four chambers: the right atrium, right ventricle, left atrium, and left ventricle.
Nov 3, 2023 · The great cardiac vein is a large blood vessel found on the anterior (sternocostal) surface of the heart. The anterior interventricular vein becomes the great cardiac vein once it has left the anterior interventricular sulcus and has entered the coronary sulcus.
Nov 3, 2023 · Blood flows from the atria into the ventricles through the atrioventricular orifices (right and left)–openings in the atrioventricular septa. These openings are periodically shut and open by the heart valves, depending on the phase of the heart cycle.
