Coronary arteries are the blood vessels responsible for delivering oxygen-rich blood to the heart. They are referred to as "coronary" because they surround the heart like a crown. The term "coronary" is derived from the Latin "corona" and the Greek "koron," both meaning crown. Similar to other arteries, coronary arteries can experience atherosclerosis, which is the hardening of the arteries. There are several coronary arteries, but the ones most commonly bypassed today include the right coronary artery, the descending coronary artery, the left main coronary artery, the left descending coronary artery, and the left coronary artery. Blockages in the coronary arteries can also be addressed using methods such as balloon angioplasty, stenting, and other medical procedures.
