Cardiovascular Diseases and Aneurysms - 1414 Words

The human body is a highly complex system of organs that operates efficiently at a cellular level to ensure proper functionality and longevity of the human race. However, even the slightest changes to its operation can lead to complications. In order to better understand the human body and how it works; an understanding of the diseases it is susceptible to is necessary. The cardiovascular system, in particular, is vulnerable to debilitating disease such as aneurysms, which is a ballooning of a blood vessel, or even an embolism (when any foreign body enters the blood stream). Blood vessels include arteries, capillaries and veins and therefore these events can occur anywhere in the body (i.e. the heart or the brain). There are different types of aneurysms including saccular, fusiform and pseudo-aneurysms. Saccular aneurysms only develop on part of the vessel wall and are spherical in shape. Fusiform aneurysms are ovoid in shape and develop over the entire vessel cross section. Pseu do-aneurysms are not true aneurysms but they occur as a result of a tear in the vessel wall thus collecting the blood pooled by extravascular tissue (Group). The exact cause of an aneurysm is not known but is correlated with certain previous existing conditions. Existing conditions that may have an effect on the development of an aneurysm are inherited predispositions to this disease, lifestyles, and high blood pressure. Some individuals are predisposed to developing aneurysms if their bloodShow MoreRelatedSmoking and the Effects on the Heart Essay1413 Words   |  6 Pagescause of disease and deaths in the United States. Smoking is among the top preventable risk factors of heart disease amongst many other health problems. Coronary heart disease and strokes are the primary types of cardiovascular disease caused by smoking. They rank as the first and third leading causes of death in the United States. More than 61 million Americans suffer from some form of cardiovascular disea se. Smoking increases your risk for high blood pressure, coronary heart disease, strokeRead MoreA Research Study On Vascular Imaging1548 Words   |  7 PagesIntroduction Vascular ultrasound (US) is an established non-invasive method of imaging the cardiovascular system. It is cheap, accessible and provides a rapid diagnosis of many vascular diseases such as presence of abdominal aortic aneurysm, deep vein thrombosis and limb arterial occlusions. The majority of vascular ultrasound currently done in the UK is trans-cutaneous ultrasound, in which the US probe obtains images of the vessels from above the skin. In recent years intravascular ultrasound (IVUS)Read MoreThe Effects Of Smoking On The Decline Of Smoking Rates1072 Words   |  5 Pagesmillion per year by 2030. Smoking is a behavioural risk factor that has been shown to greatly increase the risk of cardiovascular disease. As well as this, it has also been shown to increase the risk of cancer, chronic obstructive pulmonary disease and other respiratory diseases, and peripheral vascular disease. In those who do not smoke, second hand tobacco smoke is responsible for disease and premature death in adults and children. As well as the personal burden of smoking on the individual, smokingRead MoreStudy Of The Heart And The Cardiovascular System And Its Functions And Disorders1601 Words   |  7 PagesA.Define the field of study Cardiology is the study of the heart and the Cardiovascular system and its functions and disorders.(2) B.What do Practitioners in this field do in their jobs Practitioners of this field are called Cardiologists.(2) There are several sub-specialties in Cardiology(1,3,4,5) Nuclear Cardiology:Uses Radioactive chemicals to assess myocardial blood flow, evaluate the pumping function of the heart as well as visualize the size and location of a heart attack.
