  2. 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.

    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. 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).

  5. Coronary circulation - Wikipedia

    en.wikipedia.org/wiki/Coronary_circulation

    Interruptions of coronary circulation quickly cause heart attacks (myocardial infarctions), in which the heart muscle is damaged by oxygen starvation. Such interruptions are usually caused by coronary ischemia linked to coronary artery disease, and sometimes to embolism from other causes like obstruction in blood flow through vessels.

  6. Left anterior descending artery - Wikipedia

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

    Septals originate from the LAD at 90 degrees to the surface of the heart, perforating and supplying the anterior 2/3 of the interventricular septum. Diagonals run along the surface of the heart and supply the lateral wall of the left ventricle and the anterolateral papillary muscle.

  7. 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]

  9. Blood vessel - Wikipedia

    en.wikipedia.org/wiki/Blood_vessel

    Blood vessels function to transport blood to an animal's body tissues. In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. Blood vessels also circulate blood throughout the circulatory system.
