Recommended: Cardiovascular System

The cardiovascular system is composed of three organs. Those organs include the Heart, Arteries, and the Veins. The cardiovascular system transports blood, gases, and waste products throughout the body. It also maintains blood pressure fluid, electrolyte, and pH balance. Without the cardiovascular system our body would not be able to function and it would shut down. If our heart stopped, the blood would stop pumping and there would be no oxygen going to our brain. At this point all of the other organs in our body would then shut down. There are three different layers in the heart. There is the epicardium, myocardium, and endocardium. The first layer, which is the epicardium, is the serous membrane on the outer surface of the heart. The middle …show more content…

The tunica interna, which is the inner layer of endothelium consists of areolar tissue. The middle layer, which is called the tunica media, contains smooth muscle tissue and areolar tissue. The outer layer called tunica externa consists of areolar tissue. The main purpose of this article was to take patients without established Coronary Heart Disease and reveal the risk equivalents that they could have in the future. I believe the author’s purpose was to inform patients who are on the boarder of Coronary Heart Disease that they are at risk of developing major problems in the future. If they were not going to try and prevent this disease then it will lead to more serious health problems and maybe even death. I believe that they author did make his purpose very clear throughout the paper. They started off by choosing patients at random and conducting health examinations on each of them. This exam consisted of lab tests and like every other doctors office that I go to for the first time a questionnaire on different types of illnesses that they may have had in the past. After conduction all those tests then they went deeper and the patients had a coronary artery angiography, an ultrasonography, and an oral glucose tolerance test. When the results came back from all the tests, they excluded those patients who had more then one

    It was to this respect that, the search could detect ‘’hypertension’’ as the leading risk factor for heart disease. And this preceded three quarters of heart failures cases as compared to coronary artery disease, which led to most heart failures in less than 40% of the cases. Also, an increase in left ventricular end-diastolic diameter became a mirror to the Framingham study as incident heart diseases in the individuals who are free from myocardial infarction. Although studies have shown that, the manifestation of heart failures can be present without the left ventricular systolic dysfunction, other risk factors could lead to that. Also, they (Framingham study) were able to detect ‘’too much of cholesterol’’ as a link to cardiovascular diseases. Moreover, research believed that has elevated among certain heart diseases such as coronary heart often leads to stroke, too high blood pressure among numerous patients. Having said that, the search discovered ‘’obesity’’ also as a concomitantly with hypertension which elevates lipids and diabetes versus questions on smoking behavior. Having said that, these risk factors are believed to have attributed to heart diseases. Therefore, it became a national concern to the general US population and that of the fourth director of Framingham heart study, William Castelli

    The human body is an amazing machine, we have cells, tissues, organs and organ system that come together to create the human race. Each system plays a key role in our bodies mechanism. Without each systems our bodies would not function properly, but what happens when one of these system fails? The Cardiovascular system components are blood, blood vessels and the heart. The hearts function is to pump blood to all the major organs and tissues (Circulatory). It’s also important to be aware of the derivation that our bodies may encounter, for example a stroke. In this passage I discuss different types of strokes, what are the signs and symptoms and after care for this disorder of the cardiovascular system.

  • The Heart: The Layerss Of The Heart

    1305 Words  | 3 Pages

    . The layers of the heart wall include epicardium, myocardium, and endocardium. Epicardium is the surface of the wall and it’s also called visceral pericardium. It contains serous membrane covering the heart. Myocardium is in the middle of the two layers it’s described as having a thick muscular layer of the heart. It serves as having contractions of the heart as well in containing fibrous skeleton in networking of collagenous and elastic fibers. Some of the functions are providing structural support, attachment for cardiac muscle, and having electrical insulation. Endocardium is the inner lining that is smooth and contains epithelial. There is also the pericardial sac which allows the heart to beat without friction and the heart having room to expand and resist excessive expansion. It has three layers which include parietal pericardium the tough outer layer, pericardial cavity is filled with pericardial fluid, and visceral pericardium which is thin, smooth, and serous layer covering the heart surface.

  • Underlying Risks for Cardiovascular Disease

    1649 Words  | 4 Pages

    Since 1960 the age-adjusted mortality rates for cardiovascular disease (CVD) has declined steadily in the U.S. due to multiple factors, but still remains one of the primary causes of morbidity and premature mortality worldwide. Greater control of risk factors and improved treatments for cardiovascular disease has significantly contributed to this decline (Centers for Disease Control and Prevention, 2011). In the U.S. alone it claims approximately 830,000 each year and accounts for 1/6 of all deaths under the age of 65 (Weiss and Lonnquist, 2011). Based on the 2007 mortality rate data an average of 1 death every 37 seconds is due to cardiovascular disease (Lloyd-Jones et al., 2009). Controlling and reducing risk factors is crucial for saving lives. There are a number of contributing risk factors for cardiovascular disease, which may appear in the form of hereditary, behavioral, and psychological, all of which ultimately converge in social or cultural factors.

    The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...

    The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.

  • Pulmonary Circuit Essay

    854 Words  | 2 Pages

    The heart is the organ that pumps the blood throughout the body. It has three chambers: the atria, the ventricles, and the septum. It also contains two main valves: the tricuspid and the bicuspid (the atrioventricular valves). It has two sections that carry the different types of blood (oxygenated and deoxygenated). The oxygen depleted blood goes through the right atrium to the right ventricle. From the right ventricle the blood goes out of the pulmonary artery to the lungs; which is referred to as the pulmonary circuits. The oxygen rich blood goes from the lungs to the left ventricle. From the left atrium, it travels to the left ventricle and out through the aorta to the different parts of the body; referred to as the systemic

    The cardiovascular system consists of the heart, blood vessels. This is responsible for transporting oxygen and nutrients to all the cells in the body. This consists of the heart and blood vessels running through the body. The arteries move the blood away from the body and the veins move it to the heart. There are two circulatory systems in the body which are both connected.

    During my undergraduate degree, I became fascinated by cardiovascular reactivity; the idea that physiological reactions of differing magnitudes to acute stress of can lead to vastly different health and behavioural outcomes particularly intrigued me. It was my psychology and psychophysiology modules which first aroused this interest and completing cardiovascular reactivity-based essays further enhanced this passion. Alongside developing my understanding of the theoretical foundations that underpin cardiovascular reactivity, I also started to focus on the research that could be conducted in the area. This directly contributed to my choice of my undergraduate dissertation topic: Childhood adversity as a potential origin of cardiovascular reactivity magnitude.

    The circulatory system know as the cardiovascular system pumps blood around the body. It is made up of the heart, arteries, veins and capillaries. The heart pumps deoxygenated blood from the left side of the heart to the lungs to make you breath when exercising. When the Deoxygenated blood enters the lungs it turns into oxygenated blood then it goes to the heart and threw out all the body.

  • The Human Circulatory System

    The human circulatory is one of, if not the, most important system in the body. “It consists of such organs as the heart, and lungs” (Dunbar 4). “However every organ and organ system in the body is nourished and kept alive through the use of the circulatory system” (2-4). The main organ in the circulatory system is the heart. “Basically, the heart is a pump that keeps fresh blood coursing through your body, bringing oxygen and nutrients to all your organs and cells” (2). “A mathematical description of what the heart accomplishes is astonishing. Your heart keeps approximately ten pints (4.73 liters) of blood constantly circulating through seventy –five –thousand miles (one –hundred –thousand kilometers) of blood vessels” (2). Those thousands of miles of blood vessels reach every organ in your body. “Once they reach the organ they deliver much needed oxygen and take away carbon dioxide and other waste products that your body cannot use. This must be done without interruption if you are to remain healthy and alive” (2).
