Heart Disease Stephanie Rodriguez CHCP Abstract According to the World Health Organization‚ cardiovascular disease is the most common death in the U.S. These heart attacks and strokes are responsible for more than 15 million deaths worldwide each year. Doctors assure that every day nearly 2‚500 people in many other countries around the world die from heart diseases. In my opinion‚ the heart is a major important

The term “heart failure” sounds as if the heart has already failed. This can increase a person’s anxiety especially in the aging population that is a targeted community for this disease assuming that the failure is equivalent to death. Heart failure is actually the decline in the hearts ability to sufficiently pump oxygenated blood to the rest of the body. Many people can live with heart failure and are able to manage it through lifestyle changes‚ prescribed medication compliance‚ and regular physician
Premium Heart Myocardial infarction Blood
A heart attack is also known as a myocardial infarction. A heart attack is when a part of the heart muscle is damaged or dies because it is not receiving oxygen. A heart attack is the death of heart muscle and it is caused by a sudden block of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Causing injury to the heart muscle can cause chest main and pressure. If blood flow is not restored within 20 to 40 minutes permanent
Premium Myocardial infarction Heart Artery
Artificial Heart/ Heart Transplants A natural heart has two pumps‚ each has two chambers. The right atrium pumps oxygen-depleted blood from the body into the right ventricle. The right ventricle pumps blood to the lungs. The left atrium sends aerated blood from the lungs into the left ventricle‚ which pumps blood out of the body. With each heartbeat‚ the two atria contracts together‚ followed by the large ventricles. Congestive heart failure is when the heart fails to pump blood. Heart failure

Shonna Seddon Anatomy & Physiology II December 3‚ 2011 Heart & Lungs The heart and lungs are two separate organs‚ but are “intimately connected” for the proper function of a healthy body. With the function and purpose of both organs‚ one cannot work without the other. The lungs inhale oxygen‚ and then exhale the carbon dioxide and other wastes out of the body. With the heart‚ it pumps blood through the lungs to pick up the oxygen and deposit the waste from traveling through the

Premium Hypertension Heart
The heart level increases depending on the amount of pressure‚ intensity and type of exercise. When performing a cardiovascular exercise‚ the blood becomes directed to the muscles that are physically conducting the exercise. As well as when the blood volume and flow return to the heart‚ it increases which makes the left ventricle expand and adapt to a different situation. Due to this‚ the heart can register a higher level of blood and eject it at a faster rate to all living cells and membranes. This
