Introduction:
The heart is part of the circulatory system which pumps blood and supplies oxygen throughout our body(Jacobs). Pumped through a network of arteries and veins, blood is a very important part of our body. Without blood, we could not live. This is because it keeps us warm, fights off infections, and helps get rid of waste(Durani). Blood also transports oxygen and hormones throughout our body. Our circulatory system is made up of the heart and blood vessels. They also include arteries, veins, and capillaries. There are two parts to the circulatory system: the pulmonary circulation and the systemic circulation. The pulmonary circulation is a short loop from the heart to the lungs and then repeats. The systemic circulation sends blood from the heart to the other parts in our body and repeats(Durani).
Circulation
Veins and arteries have many differences. One difference is veins have a thinner wall than arteries do. Veins can widen as the amount of blood that passes through them increases. Arteries have strong and flexible walls that allow them to adjust blood that flows to body parts. The veins and arteries are apart of the of the circulatory system. In …show more content…
Plaque could build up in your arteries. This would cause it to narrow your coronary arteries and decrease the blood flow to your heart. Blockage percent can vary. If there is a 20-40% of blockage, it is considered to be a mild coronary artery disease. A 40-70% blockage would mean you have a moderate coronary artery disease. A severe coronary artery disease would mean you have a more than 70% blockage. If there was a 100% blockage, it would lead to a heart attack. Some things that may cause Coronary Artery Disease inlcude: smoking, high levels of certain fats and cholesterol in the blood, high blood pressure, high levels of sugar, diabetes and blood vessel
