Which 2 major anatomical branches do the coronary arteries have?
Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function, and oxygen-depleted blood must be carried away. The coronary arteries consist of two main arteries: the right and left coronary arteries, and their two branches, the circumflex artery and the left anterior descending artery.
What are the branches of the right coronary artery?
The RCA gives two major branches; the conus (arteriosus) artery and the sinoatrial artery. The conus artery is the first provided branch by the RCA; it originates from the ostium of the RCA or separately from the right coronary sinus and has a superior and anterior course. It supplies the right ventricle.
What branches into the anterior interventricular artery and the marginal artery?
It further branches into the circumflex artery and the anterior interventricular artery (left anterior descending artery). The anterior interventricular artery further divides into septal branches and diagonal branches. The septal branches supply the anterior two-thirds of the interventricular septum and bundle of His.
What is epicardial coronary artery disease?
CAC is only present in diseased atherosclerotic arteries, and thus, is a surrogate marker of atherosclerotic burden and “arterial age” (Rumberger et al., 1995; From: The Impact of Nutrition and Statins on Cardiovascular Diseases, 2019.
Where is epicardial fat located?
Epicardial fat (EF) is a visceral fat deposit, located between the heart and the pericardium, which shares many of the pathophysiological properties of other visceral fat deposits, It also potentially causes local inflammation and likely has direct effects on coronary atherosclerosis.
What are the three principal branches of the left coronary artery What are the branches of the right coronary artery?
The right coronary artery supplies blood mainly to the right side of the heart. The right side of the heart is smaller because it pumps blood only to the lungs. The left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart.
What are the three branches of the heart?
Three vessels come out of the aortic arch: the brachiocephalic artery, the left common carotid artery, and the left subclavian artery. These vessels supply blood to the head, neck, thorax and upper limbs.
What is the Conus branch?
The conus branch, often the first branch of the right coronary artery (RCA), supplies the right ventricular outflow tract (RVOT) area.
What are the three principal branches of the left coronary artery?
The circumflex branch,
What are the branches of left coronary artery?
The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart.
