    Arteries have an essential duty in the human body—to deliver oxygenated blood to the heart constantly, which is why it's vital to understand its anatomical makeup and potential anomalies.

    The left coronary artery and its branches play a crucial role in ensuring that the muscles of the heart, itself, are supplied with oxygenated blood. Specifically, it provides the majority of supply to the ventricles(the lower chambers of the heart) as well as the left atrium and atrial appendage, the pulmonary artery, and aortic root. Naturally, ...

    The central role that the left coronary artery plays in heart function means that disease or disorder of it or its branches can lead to very serious issues. Most notably, when the walls of the arteries narrow due to hardening and a build-up of plaques (atherosclerosis), the reduction in proper blood flow can lead to coronary artery disease. In thes...
