What Is The Function Of Coronary Arteries And Veins
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
What is unique about the pulmonary veins and pulmonary arteries when compared to other veins and arteries on the body?
They are backwards: All arteries in the body carry oxygenated blood from the heart. After leaving the arteries, blood enters capillaries where oxygen is dropped off and carbon dioxide waste is picked up. Veins then take the carbon dioxide back to the heart. Now here is the difference. The pulm. Arteries then take the blood with carbon dioxide to the lungs where oxygen is picked up and carried by the pulm. Veins. ...Read more

blood to heart: The coronary arteries supply blood to the heart muscle itself. There are usually 3 - the left anterior descending, circumflex, and right coronary. Closure or blockage of one of these main arteries, or a branch vessel, from cholesterol or a clot, causes a heart attack or angina (chest pain). ...Read moreSee 1 more doctor answer

Anything that damages or roughens the lining of the blood vessels could result in clot formation, such as elevated cholesterol and hypertension. Risk factors include family history of heart disease, being male, increasing age, elevated cholesterol or ldl, obesity, smoking, and being sedentary. ...Read more

Here you go: Blood enters through the vena cavae, passes through the right atrium into the right ventricle. The blood then goes out into the lungs and returns via the pulmonary veins to the left atrium. That blood then goes out the left ventricle to the body and returns via the vena cavae. The order of blood vessels is great vessels, arteries, arterioles, capillaries, venules, veins and back to the cavae. ...Read more
Another idea: Narrowing of coronary arteries usually is a result of atherosclerosis, a buildup of plaque on the arterial walls. It is the long term effect of inflammation, cholesterol and aspects of lifestyle. If someone is motivated to change exercise habits, stress levels and diet, investigate the insurers- and medicare-approved program of dr. Dean ornish (www.Pmri.Org). It's work but can reverse this. ...Read moreSee 1 more doctor answer
