2. 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 ...

4. Heart - Wikipedia

   en.wikipedia.org/wiki/Heart

   The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]

5. Coronary arteries - Wikipedia

   en.wikipedia.org/wiki/Coronary_arteries

   The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart.

6. 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 ...

7. Circulatory system - Wikipedia

   en.wikipedia.org/wiki/Circulatory_system

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

8. Blood vessel - Wikipedia

   en.wikipedia.org/wiki/Blood_vessel

   Arteries—and veins to a degree—can regulate their inner diameter by contraction of the muscular layer. This changes the blood flow to downstream organs and is determined by the autonomic nervous system. Vasodilation and vasoconstriction are also used antagonistically as methods of thermoregulation. [23]

9. Cardiac physiology - Wikipedia

   en.wikipedia.org/wiki/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.
