![]() The heart muscle itself also needs its own blood supply, so that it can get plenty of oxygen and glucose to keep respiring and keep pumping - these are called the coronary arteries. Whenever we use the word ‘pulmonary’ we are referring to the lungs. Remember than the arteries are away from the heart and veins are always going to the heart. The major vein which returns blood from the body to the right side of the heart is the vena cava and the vein which ferries blood from the lungs to the heart is called the pulmonary vein. The main artery which takes oxygenated blood from the left side of the heart to the rest of the body is called the aorta whereas the artery which delivers deoxygenated blood between the right side of the heart and the lungs is called the pulmonary artery. There are another set of valves between the ventricles and the arteries which are called the semi-lunar valves as they look like little half-moons. Blood flows from the atria to the ventricles, which are separated from the atria by atrioventricular valves to prevent blood flowing in the opposite direction. The chambers at the top are called atria and these chambers receive the blood from the veins supplying the heart. The left side carries oxygenated blood whereas the right side carries deoxygenated blood. The left side of the heart has a much thicker wall, as it needs to pump more strongly to deliver blood all around the body (whereas the right side just needs to send the blood to the lungs). Remember that the left side of the heart is always drawn on the right (so it is the left of the person who’s heart it is, rather than your left as you’re looking at the paper). The heart gets its own supply of blood from a network of blood vessels on the heart's surface called coronary arteries.The heart is made up of four chambers divided into two sides. The blood returns to your heart through veins before being pumped back to your lungs again. The oxygen-rich blood returns to your heart and is then pumped to the body's organs through a network of arteries. It pumps blood around your body and beats approximately 70 times a minute.Īfter the blood leaves the right side of the heart, it goes to your lungs where it picks up oxygen. The heart is a muscle about the size of your fist.

This process is known as atherosclerosis and the fatty deposits are called atheroma.Ītherosclerosis can be caused by lifestyle factors, such as smoking and regularly drinking excessive amounts of alcohol. Over time, the walls of your arteries can become furred up with fatty deposits. Causes of coronary heart disease (CHD)Ĭoronary heart disease is the term that describes what happens when your heart's blood supply is blocked or interrupted by a build-up of fatty substances in the coronary arteries. The main symptoms of coronary heart disease are:īut not everyone has the same symptoms and some people may not have any before coronary heart disease is diagnosed.
