The difference between coronary arteries and the aorta

There are differences between the two, including definitions and functions. The latter is larger, originates from the heart, and is responsible for blood supply throughout the body. The former specifically refers to the vessels that nourish the heart; they originate from the root of the aorta. Diseases of the aorta can affect systemic blood supply, leading to widespread ischemia and hypoxia. Coronary artery disease, also known as coronary heart disease, primarily affects blood supply to the heart, causing myocardial ischemia and hypoxia, and even myocardial infarction.
