Where Do Coronary Arteries Empty Their Blood
Heart Muscle: The coronary arteries arise from the aorta and course over the surface of the heart. They supply blood to the heart muscle with nutrients and terminate in small connections called capillaries with heart veins. The health of these vessels is very important. If they become "clogged" with cholesterol plaque then the blood suppy to the heart is reduced leading to chest pain and heart attacks. ...Read moreSee 1 more doctor answer
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
Yes, except: Yes, except in areas of infarction where the myocardial cells have died. Infarcted myocardium is dead heart tissue. This is usually the result of a myocardium infarction, mi, or heart attack.

Since having a full hysterectomy in february I have had problems with high blood pressure and coronary artery spasms. Are these related?
Not likely: Coughing up blood is usually a problem of the lung tissue or gastrointestinal track. Atheroma of the blood vessels is a complication of dietary intake and genetic makeup. While poor heart function as a result of atheroma may cause the lungs to function poorly, bloody coughs are not common. You should see your doctor for this condition as there may be something more serious going on. ...Read moreSee 1 more doctor answer

Really, really not: You're making costochondritis sound like a big deal. Perhaps it wasn't explained to you that it isn't. Few people don't get shooting pains in their chests at some time. To doctors costochondritis is like the common cold: Can't be avoided, predicted, or prevented & it's benign. Costochondritis is a fancy word for "nothing's wrong with you." My advice: Find something else ro worry about. ...Read moreSee 1 more doctor answer
