Cardiovascular System: The Deadliest Heart Disease
The body system that most interests me is the cardiovascular system, I chose this system because I’m fascinated with how the heart works and how the blood flows throughout our whole body. The heart is a muscle that contracts which allows blood to be pushed throughout the body. The heart provides many nutrients and blood to the whole body along with many vital organs. The heart is spilt into four chambers: the right atrium, left atrium, left ventricle, and right ventricle. The blood flow starts in the right atrium then moves through the tricuspid valve into the right ventricle. From the right ventricle it will move through the pulmonary valve which goes through to the pulmonary artery. From the pulmonary artery the blood will travel to the

Then they will have machine that will pop up a graph to show theses electrical changes. Another major component of the heart is the pulmonary vein which arises from each lung and brings oxygenated blood from the lungs to the left atrium and then we have the coronary arteries that arise from the aorta and supply blood to the heart muscle which is very important so any blockage could be very fatal and cause numerous condition. Coronary heart disease is the deadliest heart disease in America affecting 13 million people a year, this disease occurs when there is a buildup of plaque in the myocardium and in the coronary arteries which makes the artery rigid, stopping blood flow, which also can stop oxygen flow killing vital organs. After a while the plaque in the heart could rupture causing a heart attack and sudden cardiac death. The plaque can start building up at a young age and as you get older it will build and keep going, but the plaque itself will release chemicals that will make blood vessels sticky. Signs and symptoms of this disease could be shortness of breath, irregular heartbeats, a small myocardial infarction, and …show more content…
Then the tissue is connected to the coronary artery right before the blockage so it will creates a new lining that will for the vessels and makes a new path around the plaque to keep blood flow going. Another major heart disease is Angina which is caused by Atherosclerosis, Angina is a major chest pain that is caused by the blockage of blood supply to the heart. The pain will often shift to the left arm or left shoulder along with your jaw, neck and upper back. There are several types of angina. The most common type of angina is stable angina. Stable angina is when the heart may work harder than usual when doing some activities during the day then it will start a pattern that will occur during the day which will happen every time you do that daily activity. Most people may think it is a heart attack but it’s not it may just be warning you that it could happen in the future. The other type is called unstable Angina which is when the pain just happens at random times and they don’t follow a pattern like the stable angina. The pain could come during rest or work there is no trigger for
