The Cardiovascular System
The Cardiovascular System
David Clarke is 30 years old, stands 6’ and weights 225 lbs. He commutes between Miami where he is a full time student, and Hialeah, where he works as a paramedic. He sleeps only two to four hours per night. Brian is overweight and does very little exercise. He also admits to eating mostly fatty foods. Both David’s grandmother and father have suffered heart attacks. According to new statistics, “despite the recent decline in mortality from coronary heart disease, this disease remains the leading killer of US adults of all ages” (Rubin JB 1). Heart disease is the result of poor diet, lack of exercise, stress and a host of others which is why David Clarke should be concerned. With his current lifestyle Brian may be or become one of 27.1 million Americans with heart disease (Heart Disease par. 1). Coronary heart disease is a disease of the blood vessels supplying the heart muscle. This is just one disease out of many that may emerge within the much larger cardiovascular system. This system consists of the organs and tissues involved in circulating blood and lymph (white blood cells) through the body. New studies showed that donor stem cells taken from adult bone marrow were found to be just as effective in treating diseased hearts as injecting patents with their own stem cells (“Donor Stem Cells Just As Good For Heart Patients” par. 2). The advantage of using donor stem cells is it reduces the time taken to prepare the large quantities of cells thus cutting down on waiting time considerably. Cardiologists have been able to understand the function on the cardiovascular system in order to develop and discover new prevention methods, heart disease and future prognosis.
Blood that is high in carbon dioxide is pumped from the right side of the heart to the lungs. Here at the lungs the blood is oxygenated and taken back to the left side of the heart. As the right ventricle of the heart contracts deoxygenated blood is pumped through the pulmonary
