2. Coronary circulation - Wikipedia

   en.wikipedia.org/wiki/Coronary_circulation

   The relatively narrow coronary arteries are commonly affected by atherosclerosis and can become blocked, causing angina or a heart attack. The coronary arteries are classified as "terminal circulation", since they represent the only source of blood supply to the myocardium; there is very little redundant blood supply, that is why blockage of ...

3. Coronary arteries - Wikipedia

   en.wikipedia.org/wiki/Coronary_arteries

   Heart failure is caused by chronic oxygen deprivation due to reduced blood flow, which weakens the heart over time. Arrhythmias are caused by inadequate blood supply to the heart that interferes with the heart's electric impulse. The coronary arteries can constrict as a response to various stimuli, mostly chemical. This is known as a coronary ...

4. Circumflex branch of left coronary artery - Wikipedia

   en.wikipedia.org/wiki/Circumflex_branch_of_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]

   This is achieved by the coronary circulation, which includes arteries, veins, and lymphatic vessels. Blood flow through the coronary vessels occurs in peaks and troughs relating to the heart muscle's relaxation or contraction. [8] Heart tissue receives blood from two arteries which arise just above the aortic valve.

7. Cardiology - Wikipedia

   en.wikipedia.org/wiki/Cardiology

   Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (the myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.

8. 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 ...

9. Cardiac physiology - Wikipedia

   en.wikipedia.org/wiki/Cardiac_physiology

   The function of the right heart, is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation ...
