What do the coronary arteries and veins do?

Coronary A/V: The coronary arteries take blood from the aorta to the heart and the coronary veins drain the blood from the heart. The heart is a muscle, therefore, it requires blood to function. When a coronary artery becomes blocked then a heart attack can occur. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

Are there differences in appearance between coronary arteries and veins?

Are there differences in appearance between coronary arteries and veins?

Yes: Yes, the coronaryveins are thin walled vessels like all veins. The arteries are thicker, muscular walled structures as the coronary arteries actively dilate and contract in response to cardiac demands and various signals. In many instances, the coronary venous structures travel right next to the arteries. ...Read more

Do ARB'S and Nitro work the same way? (Relax vessels) If so; will ARB'S relax coronary arteries?

ARBs and Nitro work?: Do ARB'S and Nitro work the same way? (Relax vessels) If so; will ARB'S relax coronary arteries? ANS: No ARBS work by blocking high blood levels of angiotensin II. Nitro works directly on arterial muscles. But both may "relax" blood vessels. ARBS by AII receptor occupation and nitro directly. ...Read more

How do the coronary arteries work?

How do the coronary arteries work?

Carry blood: The coronary afteries are located just above the aortic valve. Blood flows through those arteries and suppies oxygen to the heart muscle. A number of factors can cause the arteries to dilate (become wider) so that the flow of blood can increase if needed such as when you exercise. ...Read more

What's the purpose of the coronary arteries?

Feed heart muscle: In humans usually two main coronary arteries come off the aorta to feed the heart muscle. The right coronary feeds the right side of the heart and some of the muscular wall between the two sides. The left coronary divides into the left anterior descending artery and the circumflex coronary artery. The arteries bring oxygen and food to heart muscle cells. ...Read more

What is the location of the coronary arteries?

Picture this: The coronary arteries branch off from the walls of the aorta, and dive down into the outer layer of the heart mucle. On the left side, the left main artery branches into the left anterior decending (lad), which runs down the front wall of the heart, and the circumflex, which runs around the lateral wall. On the right, the right coronary artery runs along the bottom wall of the heart. ...Read more

What causes thrombosis of the coronary arteries?

What causes thrombosis of the coronary arteries?

Arterioclerosis: Arteriosclerosis or plaque buildup in the wall of the coronary arteries will narrow the lumen to the point where there is flow restriction, then clot formation. The plaque may rupture, allowing a flap-like effect, blocking the lumen, resulting in clot formation. Trauma may cause a separation of the layers of the wall, and this dissection results in clot formation. ...Read more
