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 ...
In addition to a heart attack, here are some more heart-related issues for chest pain on the left side. As Dr. Bairey Merz says, these are not conditions you can self-diagnose. Call 911 at once to ...
The left coronary artery arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the left anterior descending and the left circumflex. The left anterior descending artery perfuses the interventricular septum and anterior wall of the left ventricle. The left ...
The circumflex branch of left coronary artery (also known as the left circumflex artery or circumflex artery [citation needed]) is a branch of the left coronary artery. It winds around the left side of the heart along the atrioventricular groove (coronary sulcus). It supplies the posterolateral portion of the left ventricle. [1]
The left heart has two chambers: the left atrium and the left ventricle, separated by the mitral valve. [8] The left atrium receives oxygenated blood back from the lungs via one of the four pulmonary veins. The left atrium has an outpouching called the left atrial appendage. Like the right atrium, the left atrium is lined by pectinate muscles. [25]
If your biggest concern about your heart is the burn you feel at 3 a.m., flip over to the left side and drift back to sleep. "Sleeping on the left side often helps with acid reflux," Dr. Vuppuluri ...
The left coronary artery (LCA, also known as the left main coronary artery, or left main stem coronary artery) is a coronary artery that arises from the aorta above the left cusp of the aortic valve, and supplies blood to the left side of the heart muscle. [citation needed] The left coronary artery typically runs for 10–25 mm, then bifurcates ...
This is opposed to dextrocardia, in which the heart is in the right side. Neither levocardia nor dextrocardia are indicative of the orientation of the visceral organs , which can be in situs solitus , where the remainder of the organs are on normal side as well; or situs inversus , in which the viscera (stomach, liver, intestines, lungs, etc ...
