The human heart contains two primary arteries, which are called coronary arteries. The purpose of these arteries is to transport oxygenated blood to the heart, which allows it to function effectively. The two main arteries are called the left main coronary artery (LMCA) and the right coronary artery


There are two main arteries that lead to the heart, where each major artery branches into two smaller arteries, which makes a total of six, according to Cleveland Clinic. The blood vessels that supply the heart with oxygen-rich blood are referred to as coronary arteries.


Arteries are blood vessels within the body that provide oxygen-rich blood to the tissues in the body, as defined by WebMD. The arteries are able to deliver this oxygen due to the pumping mechanism of the heart.


The largest artery in the human body is the aorta, which connects directly to the heart’s left ventricle. There are no arteries inside the heart, but there are many on the exterior of the heart, called coronary arteries. Coronary arteries bring blood directly to the tissues of the heart.


Calcium in the arteries sometimes indicates a higher risk of heart attack. The deposits narrow the arteries and decrease blood flow. A coronary calcium test or heart scan looks for these deposits and the results are sometimes called a coronary calcium score, according to Mayo Clinic.


According to HealthCentral, the artery that runs from the heart to supply blood to the rest of the body is the aorta. Many forces in the body cause the aorta to weaken, and as it weakens, it becomes enlarged. Enlarged aortas are fairly common, especially in people who have high blood pressure, are o


The function of the arteries is to carry oxygenated blood to organs and cells in the body. Because of this, arterial blood has a bright red color and flows away from the heart.


Looking at a coronary artery diagram teaches the viewer about the different parts of the heart and their location. A diagram from Cleveland Clinic shows the functions of each part of the heart, according to the Cleveland Clinic website.


Arteries have three main layers or tunics known as the adventitia (outer), media (middle) and intima (inner). The outer layer is made of connective tissue with collagen fibers, the middle layer consists of smooth muscle and elastic fibers, and the innermost layer is composed of specialized squamous


Also referred to as peripheral artery disease, arterial disease in the legs is caused by a condition called arteriosclerosis, hardening of the arteries. This condition occurs when plaque accumulated on the walls of the arteries making them narrow. Consequently, the arteries become stiffer, inhibitin
