Human anatomy and physiology Essay

The cardiovascular disease has been one of the most fatal diseases in the world. And nowadays, it has been categorized into one of the wide ranging and investigative illness in the world. It is a disease merely composed of various individual disorders mainly in the heart and in the organs building the circulatory system. For many years, this disease has been one of the chief causes of death not only in the United States but also in the other parts of the world. And for that, this disease has been one of the challenges that still on top of the challenges that are being faced by the experts in health and medicinal tasks. The coronary heart disease and the cerebrovascular disease are two of the several diseases that compose the cardiovascular disorders. Though experts have already tried easing down the death rates caused by this disease, still the cardiovascular disease along with many of its components haunts the bodies of the persons of their next victims. One million deaths which are mostly rooted on the cardiovascular diseases have been recorded during the year of 1997 and up to this year is still increasing and heaving up with it a huge amount of expenditure not only of the victims but also of the persons preventing and thinking ways on how to prevent and treat the disease. However, not long before this disease of the heart and of the circulatory system had come into view, there were also other diseases that had bothered the health of the United States. Diseases like the pneumonia, diarrhea, tuberculosis and others have been the main illness that the United States have been battling with. It was not until 1963 that the deaths caused by coronary heart disease have took over in having the highest record. Over the years of the deaths caused by the cardiovascular diseases, experts all over the world began studying on the primary causes of this disease. According to the studies, the factors affecting the occurrence of this disease can be categorized to two: the modifiable and the not modifiable factors. The second one, the not modifiable factors are the ones that are mostly of the genetic preferences. Examples of these factors are gender of the person and family background regarding the disease. On the other hand, the first factor, the modifiable factors are the factors that can still be controlled or managed by the person in order not to have the disease. High blood pressure, fat or cholesterol level in the body, smoking, and pressure of the person’s blood, blood sugar, obesity and physical inactivity of the person are cases of the modifiable factors of the cardiovascular diseases. Reaction The cardiovascular system is one of the various systems in the body. This system is the one responsible for the transport of the following: hormones, food, gases and metabolic wastes. The system is composed of three major components: the blood, the blood vessels and the heart. The blood is composed of plasma and cells and serves as the transport vehicle of the ones transported by the system. The blood vessels on the other hand are grouped into two: the arteries and the capillaries. These blood vessels are the passageway of the blood to and from the different organs of the body. The arteries are channels that carry blood away from the heart and the capillaries are the ones that transmit blood from the different organs back to the heart. And finally the heart; this is the component of the cardiovascular system that drives the blood into motion. Definitely the cardiovascular system is one of the systems needed by the body to sustain life. If not for this system, there would be no transport of blood therefore the body would not be provided with the proper nutrients and gases and thus leading to death. Cardiovascular disease as stated in the article by William T. Friedwald is a disease composed by many other individual diseases either in the heart or in the other parts of the body mostly on the circulatory system. For one, the coronary heart disease is one of the various disorders that compose this cardiovascular disease. And like the other components of the said disorder, the coronary heart disease is also one of the leading causes of death and expenses in the world. Coronary Heart Disease The coronary heart disease is a problem in the heart which is caused primarily by a disorder in the coronary arteries. The coronary arteries are the channels which sustains the heart with sufficient blood that provides the needed nutrients and oxygen. A problem in the coronary arteries causes the heart to have less or even none of the needed average blood in the heart. A deficiency in the supply of blood in the heart is the main reason for the occurrence of this disease. The deficiency of blood in the heart which supplies the nutrients and the needed gases is also known as ischemia that is why this disease is often referred to as the ischemic heart disease. Like any other diseases, the coronary heart disease has its own causes. One of the reasons for the existence of this disease is due to heredity. Coronary heart disease can be present in the blood that runs through the veins of your family. And so, if one of the ancestors of a person has exhibited the signs of this disease in the past, it would not be a wonder if the person too would have the possibility of having the disease. A high level of cholesterol in the body also aids in the development of the disease. These are also accompanied with the high blood sugar, high blood pressure and intense amount of excess fat in the body. These along with the abuse of tobacco, lack of regular physical activities and stresses brings about coronary heart disease. Lessen Tobacco Intake Smoking as a major cause of this disease should be definitely be lessened or most accordingly be brought to a stop. Too much intake of tobacco serves as grounds for the accumulation of fatty substances in the arteries. This build-up of fats in the arteries causes the narrowing of the arteries of these vessels therefore diminishing the deliver of nutrients and oxygen to the heart leading to heart attack. A gradual decrease in the intake of tobacco in the body may help in preventing the disease. Though it may sound unusual and that it is far from the existence of the disease, dieting can be an aid in preventing coronary heart disease. Dieting reduces the not only the cholesterol and sugar but also diminishes the blood pressure of the person. Researches conclude that the consumption of fish is better than eating meat. Researchers recommend the eating of fishes over meat for the reason that most of the meat especially red meat has a greater quantity of cholesterol than fishes. Moreover, certain fishes contain omega-3 which reduces the occurrence of irregular heartbeat which is the mere cause of loss from coronary heart disease. Be Physically Active Physical activities such as swimming and biking are recommended by most of the experts in order to prevent coronary heart disease. Being physically inactive is a big risk for the existence of coronary heart disease. Experts say that adults should engage themselves into activities with moderate intensity everyday. Cardiology Exam Everyone on Earth has the possibility of having the disease in their family history. Hence, a cardiology exam is advised for an early prevention and treatment program may be executed in case there is a positive result after the exam. Hormone Replacement Though not for everyone, researches have already concluded that estrogen has the ability to protect the blockage on the passageways of the blood. This has been formulated because of the observation that it is uncommon for women to experience heart attacks on pre menopausal stages of their lives. Though deadly and fatal as it may seem, the coronary heart disease can also be prevented in any ways like other diseases. Moreover, given the incurable and terminal effects of this disease, there is really a definite reason to know the ways of preventing this disease. Cardiovascular disease is a general diagnostic category consisting of several separate diseases of the heart and circulatory system. Cardiovascular diseases have been the major health problem and the leading cause of death in the United States for several decades. Despite impressive and sustained declines in the mortality rates from these diseases, the magnitude of the problem is still staggering. In 1997 alone, nearly 1 million people died of cardiovascular disease, which was about 40 percent of all deaths. The two most important components are coronary heart disease and cerebrovascular disease, with 460,390 dying of coronary heart disease and 158,060 dying of cerebrovascular disease in 1998. In 2000, it was estimated that cardiovascular diseases carried a direct heath expenditure cost of $186 billion and additional indirect costs of $190 billion, making these diseases a continuing major contributor to the escalating cost of health care in the United States.
