coronar

Coronar refers to a specific anatomical structure within the heart. It is a term derived from the Latin word "corona," meaning crown, and is used to describe a ring-like arrangement of vessels or structures. In cardiology, coronar most commonly pertains to the coronary arteries. These vital arteries are responsible for supplying oxygen-rich blood to the heart muscle itself.

The coronary arteries originate from the aorta, the main artery carrying oxygenated blood from the left ventricle of the heart. They then branch and encircle the heart, much like a crown, providing nourishment to the myocardium. Blockages or narrowing of these arteries, often due to atherosclerosis, can lead to conditions like angina pectoris and myocardial infarction (heart attack). Therefore, the health of the coronar system is critical for overall cardiovascular function. Medical imaging techniques such as coronary angiography are used to visualize and assess the condition of these vessels.
