2. Coronary circulation - Wikipedia

   en.wikipedia.org/wiki/Coronary_circulation

   Coronary circulation is the circulation of blood in the arteries and veins that supply the heart muscle (myocardium). Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated. Because the rest of the body, and most especially the brain, needs a steady supply of ...

3. Coronary arteries - Wikipedia

   en.wikipedia.org/wiki/Coronary_arteries

   Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart muscle. Without enough blood supply (ischemia), the heart is unable to work properly, especially under increased stress.

4. Circulatory system - Wikipedia

   en.wikipedia.org/wiki/Circulatory_system

   The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [1][2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and from Latin vascula ...

5. Coronary artery disease - Wikipedia

   en.wikipedia.org/wiki/Coronary_artery_disease

   Coronary artery disease (CAD), also called coronary heart disease (CHD), ischemic heart disease (IHD), [13] myocardial ischemia, [14] or simply heart disease, involves the reduction of blood flow to the cardiac muscle due to build-up of atherosclerotic plaque in the arteries of the heart. [5][6][15] It is the most common of the cardiovascular ...

6. Anatomy of the human heart - Wikipedia

   en.wikipedia.org/wiki/Anatomy_of_the_human_heart

   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 ...

7. Left anterior descending artery - Wikipedia

   en.wikipedia.org/wiki/Left_anterior_descending...

   The left anterior descending artery (also LAD, anterior interventricular branch of left coronary artery, or anterior descending branch) is a branch of the left coronary artery. It supplies the anterior portion of the left ventricle. [1] It provides about half of the arterial supply to the left ventricle and is thus considered the most important ...

8. Cardiac physiology - Wikipedia

   en.wikipedia.org/wiki/Cardiac_physiology

   Cardiac physiology. Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.

9. Right coronary artery - Wikipedia

   en.wikipedia.org/wiki/Right_coronary_artery

   In the blood supply of the heart, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. [1][2] It travels down the right coronary sulcus, towards the crux of the heart. [1][3] It gives off many branches, including the sinoatrial nodal artery, right marginal ...
