Proper circulation is essential for general health and well-being. Healthy arteries and blood vessels carry essential nutrients and oxygen to tissues and organs throughout the body. Certain natural supplements can strengthen blood vessels and...
The coronary arteries are the blood vessels that supply the heart with blood. There are two coronary arteries: the right coronary artery and the left coronary artery. The right coronary artery supplies blood to the right side of the heart, which...
An angiogram is an X-ray of the arteries and vessels that supply blood to the heart or brain. A catheter is inserted into a blood vessel from the arm or groin. Once in position, a dye is released into the artery, which makes the vessels visible...
The heart supplies the rest of the body with oxygenated blood. This may lead people to wonder how the heart muscle and tissue itself are supplied with oxygenated blood. The answer is simple: The heart gets oxygenated blood from itself. Oxygenated...
Angiography is a procedure in which specialized imaging techniques help to analyze the flow of blood through blood vessels. A dye that is visible by x-ray, called contrast dye, is injected into the catheter, and x-rays are used to visualize blood...
The heart's pumping action ensures that blood is delivered to all parts of the body; the heart itself needs adequate blood supply to perform its functions effectively. The American College of Cardiology notes that ischemic heart disease can also...
Three-vessel coronary disease describes problems with three different coronary arteries. The coronary arteries are essential because they supply blood to the heart; problems with these arteries can disrupt blood flow to the heart, which can be...
Blood vessels, along with the heart and blood, make up part of the circulatory system. At the center of this system is the heart, which pumps blood through the body. The blood carries nutrients, oxygen, and waste products (such as carbon dioxide)...
The American Heart Association reports one in three adults develop high blood pressure or hypertension in their lifetime. Lifestyle changes and medication therapy form the basis for treatment of hypertension. "Current Diagnosis and Treatment...
Cholesterol is made up of two components: high density lipoprotein, or HDL, and low density lipoprotein, or LDL. The HDL cholesterol is considered the "good" cholesterol, because it eliminates artery plaque from the blood vessels. The LDL is...
The heart and the circulatory system are the components of the cardiovascular system. The function of the cardiovascular system is to circulate blood through out the body.The healthy heart beats on average of 100,000 times daily. It receives...

Circulation problems in the feet can cause your feet to feel cold, tingly and numb. In addition, blood flow problems make it difficult for your feet to fight off any infections or to heal properly from injuries. These complications make it...
The circulatory system is a closed network of transport vessels responsible for delivering nutrients and removing waste products from all body systems. Shirley A. Jones's "Pocket Anatomy and Physiology" provides a pictorial guide illustrating the...
Blood pressure is the force of blood against the walls of your arteries. Blood pressure is recorded as two numbers. The systolic pressure is the arterial vessel pressure as the heart beats. Diastolic pressure is the arterial vessel pressure as the...
Blood vessels are hollow tubes that allow blood to flow throughout the body. If all the blood vessels of an adult, including the veins, arteries and capillaries, were laid end to end, they would stretch for 100,000 miles, according to information...
Arteries are blood vessels that carry blood away from the heart. There are many arteries in the body that carry blood to different areas, including the brain, kidneys, arms and legs. Diseases of the artery interfere with normal blood flow and can...
Coronary vessel disease, also known as coronary artery disease, is a condition in which plaque builds up in the heart's major blood vessels. This can lead to the narrowing of vessels and eventual obstruction.
Blood vessel disease is a grouping of disorders that affect the arteries, including the coronary, carotid and peripheral arteries. The one component that most of these conditions have in common is atherosclerosis, which is characterized as the...
Small vessel disease or a small vessel stroke is also called a lacunar infarction. The National Stroke Association notes that it occurs when the flow of blood in a small arterial vessel leading to or in the brain is blocked. Small vessel strokes...
Calcium channel blockers are a medication used to control high blood pressure, also called hypertension. When arteries and blood vessels carry blood from your heart to the rest of your body, it creates pressure in the artery and vessel walls. High...

MedlinePlus defines carotid artery surgery as an operation to redirect adequate blood flow to the brain. There are two carotid arteries, located on both sides of the neck, which supply the brain and facial region with blood. Obstruction can occur...
Hypertension, or high blood pressure, affects approximately 65 million people in the U.S., according to the Merck Manual for Healthcare Professionals. Thirty percent of them don't know they have hypertension. The U.S. Department of Health and...
Heart blockage, or coronary artery disease known also as CAD, is caused by atherosclerotic plaques that fill the coronary artery and impede blood flow to the heart muscle. According to the Cleveland Clinic, 13 million people have a history of...
The coronary arteries are the blood vessels that supply the heart with blood. The two coronary arteries are the right coronary artery and the left coronary artery. Silent coronary artery disease occurs when a blockage in the coronary arteries...
Coronary artery disease tops the list of the most prominent cardiac diseases, according to the Centers for Disease Control and Prevention. Others include heart failure,---sometimes called "congestive heart failure" and peripheral vascular disease,...
Heart disease has no prejudices. It affects men and women of all races. According to the Centers for Disease Control and Prevention, in 2006, 26 percent of deaths were caused by heart disease. Risk factors for heart disease include smoking, high...
Atherosclerosis is a disease that inflames and constricts arterial blood vessels, at times obstructing circulation and requiring surgical intervention. Learn more about atherosclerosis, causes and symptoms, in this health video.
High blood pressure or hypertension is a medical condition in which the blood pressure is chronically elevated. Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. Learn...
