...Cardiovascular system is transporting system used by the body to export nutrients and oxygen to the body through arteries and remove carbon dioxide by taking it to the lungs through the veins. The walls of capillaries are consist of only one endothelial cell, that is where oxygen and carbon dioxide gets exchanged. The human heart is divided into four chambers; the two upper chambers are called atria and the lower two chambers are called ventricles. The chambers are separated with barriers called septa. The upper chambers are separated with interatrial septum and the lower two ventricles are separated with intraventricular septum. The right side of the heart pumps the deoxygenated blood to the lungs and the left side of the heart pumps the...

...Cardiovascular system It consists of the heart and blood vessels (arteries and veins). The heart It is a muscle that functions as an extremely powerful pump to drive blood through the arteries and suck the blood from the veins come. The size of the fist, weighs about 300 grams and pump 5 liters of blood per minute. The heart represents only 0.4% of total body weight but consumes 10% of the oxygen provided by breathing. Arteries These are the vessels that carry blood from the heart to all organs. The transported blood through the arteries carries oxygen to organs and provides essential nutrients for their proper functioning. Veins These are the vessels that carry blood from the organs to the heart. The blood transported through the veins is...

...Before we begin to discuss the effect massage does, or does not have on the cardiovascular system, first I will clearly define both. The cardiovascular system, is an organ system that helps the body to maintain homeostasis, by way of blood circulation and the transport of nutrients, oxygen, hormones, carbon dioxide, and blood cells that flows throughout the body to help fight disease, and stabilizes the normal body functions. Such diseases that I will be discussing, and that are effected by the cardiovascular system are, heart disease, leukemia, cardiac arrest, and congestive heart failure. Massage, on the other hand is the manipulation of the muscle and connective tissue, that helps to enhance function, and helps to aid the healing process...

...Research Paper: Toxicant MOS 5425 – Advanced Toxicology 2/3/2015 Background This paper will compare and contrast a toxin that affects the nervous system, one that affects the endocrine system and another that affects the cardiovascular system. Identify the characteristics that are shared by these toxins and characteristics of these toxins make these toxins vulnerable to toxicity of these specific systems? Central Nervous System Environmental contamination has exposed humans to various metal agents, including mercury. This exposure is more common than expected, and the health consequences of such exposure remain unclear. Mercury in the past was used in a numerous different activities, and now, exposure to this metal from both natural and artificial sources is significantly increasing. According to Azevedo, et al (2012), numerous studies show that high exposure to mercury can induce the following changes to humans such as the central nervous system, potentially resulting in irritability, fatigue, behavioral changes, tremors, headaches, hearing and cognitive loss, dysarthria, incoordination, hallucinations, and death. Endocrine System According to the Canadian Centre for Occupational Health and Safety, Endocrine disruptors are found in synthetic chemicals used in industrial solvents, lubricants, and their byproducts such as polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), and dixons. Other examples of endocrine disruptors include bisphenol A (BPA)...

...Data to Knowledge Analysis Patricia Warble University of Maryland April 26, 2015 Data to Knowledge Analysis It is estimated that at least 94% of the U. S. population have at least one cardiovascular/stroke risk factor, with major risk factors (diabetes, hypertension, hyperlipidemia, smoking, obesity) in at least 38% (Roger, et al., 2012). The presence of peripheral arterial or carotid disease detected during community cardiovascular screening changes risk stratification. Evidence-based treatment guidelines, such as aspirin and statin use can be implemented in those with risk factors to minimize the risk of a life threatening or debilitating health event such as myocardial infarction or stroke. The Dare to Care (DTC) program is a community cardiovascular screening program that utilizes ultrasound to screen for carotid atherosclerosis and abdominal aneurysm, in addition to peripheral arterial disease, hypertension (HTN), and self-report risk factor assessment. A clinical question of interest: How effective is a community cardiovascular screening program in identifying persons with subclinical atherosclerosis, who are at risk and not on appropriate preventative treatments such as aspirin and statins? The purpose of this paper is to identify potential data sources, discuss data access implications, and identify strengths and weaknesses of data sets and identity potential data analysis testing tools. Potential Data Sources The DTC program utilizes an old FoxPro SQL database...

...Homocysteine and The Cardiovascular System Abstract Cardiovascular disease is considered to be the leading cause of death to date. There are many factors that contribute to cardiovascular disease. Some factors are conventional and straightforward, while others are unconventional and overlooked (Dwivedi, Tripathi, Shukla, Khan, Chauhan, 2011). Homocysteine is an amino acid found in the body that helps to build and maintain tissue. High levels of homocysteine have been linked to endothelial damage to the blood vessels. This damage can lead to plaque formation, thus atherosclerosis can ensue (American Heart Association, 2012). Although there are many causes of hyperhomocysteinemia, research has shown that nutritional replacement has helped to lower the level. Folic acid and B vitamins have shown to decrease homocysteine levels and thus help decrease plaque formation. Patients with high levels of homocysteine are instructed to include folic acid and b vitamins in their diet, restrict methionine, and exercise. Homocysteine is an unconventional risk factor for cardiovascular disease, and can also be used as a risk marker (Milani & Lavi, 2008). Homocysteine and The Cardiovascular System Cardiovascular disease involves all the diseases that affect the heart and vessels. There are many different diseases that affect the cardiovascular system. Atherosclerosis is one of these diseases. Atherosclerosis is characterized by the accumulation of soft, fatty and fibrinous...

...Sleep Apnea and Cardiovascular Disease Snoring is a common disorder that affects millions of people around the world. Snoring occurs during sleep and most people who snores do not realize that they snore, unless told by others who hear them produce a snoring sound. Even though normal snoring is not dangerous to human health, having repeated breathing stops during the snoring process can be life threatening to the snorer. According to the American Heart Association (2012) study, having repeated breathing stops during the snoring process is dangerous and can result in the development of cardiovascular problems and even death. This condition is known as sleep apnea. In this respect, an individual with sleep apnea experiences repeated breathing stops for as many as thirty times in an hour when asleep. Such episodes are dangerous for the snorer since it increases the risk of developing heart failure, high blood pressure, stroke, and arrhythmia. Research shows that one in every five people suffers from sleep apnea. America, in particular, has one of the highest incidences of people with the disease. According to Lettieri (2010), about 15 million adults suffer from obstructive sleep apnea in America. The majority of people with sleep apnea are patients with cardiovascular problems and hypertension. As earlier mentioned, this condition is life threatening and require early treatment. This document will examine the historical evidence of the disease, its causes, and its clinical effects...

...Volume 3, number 2 What is critical appraisal? Sponsored by an educational grant from AVENTIS Pharma Alison Hill BSC FFPHM FRCP Director, and Claire Spittlehouse BSc Business Manager, Critical Appraisal Skills Programme, Institute of Health Sciences, Oxford q Critical appraisal is the process of systematically examining research evidence to assess its validity, results and relevance before using it to inform a decision. q Critical appraisal is an essential part of evidence-based clinical practice that includes the process of systematically finding, appraising and acting on evidence of effectiveness. q Critical appraisal allows us to make sense of research evidence and thus begins to close the gap between research and practice. q Randomised controlled trials can minimise bias and use the most appropriate design for studying the effectiveness of a specific intervention or treatment. q Systematic reviews are particularly useful because they usually contain an explicit statement of the objectives, materials and methods, and should be conducted according to explicit and reproducible methodology. q Randomised controlled trials and systematic reviews are not automatically of good quality and should be appraised critically. www.evidence-based-medicine.co.uk Prescribing information is on page 8 1 What is critical appraisal What is critical appraisal?

...Hispanic race is growing in the United States which will add to the diverse old population. This growth change will create difficulties for policy makers and programs such as Social Security and Medicare. Both Social Security and Medicare are necessary for the elderly to survive. We need to ensure that our government enacts legislation that helps us and preserves our way of life, most important, Social Security and Medicare. Because there is less funds given toward the elderly through Social Security and Medicare, there are people working through their retirement years in order to survive. There are seven health challenges related to aging; Obesity and Metabolic Syndrome, Arthritis, Osteoporosis and Falls, Cancer, Cardiovascular Disease also known as CVD, Vision and Hearing Loss, and Memory and Emotional Well-being. Two trends that will increase...

...SBI4U ISP Part II: Genetic Technology Research Paper Embryonic Stem Cell Use Abstract: Researchers discovered that embryonic stem cells could be originated from early human embryos. This discovery has raised a series of ethical and public-policy questions that are now being confronted by multiple international organizations, nations, cultures, and religious traditions. This essay surveys policies for human embryonic stem cell research in four regions of the world, reports on the recent debate at the United Nations about one type of such research, and reviews the positions that various religious traditions have adopted regarding this novel type of research. In several instances the religious traditions seem to have influenced the public-policy debates. There are many ways in which human stem cells can be used in research and the clinic. Studies of the medical use of Embyonic Stem cells will yield information about the complex events that occur during human development. A primary goal of this work is to identify how undifferentiated stem cells become the differentiated cells that form the tissues and organs. Scientists know that turning genes on and off is central to this process. Some of the most serious medical conditions, such as cancer and birth defects, are due to abnormal cell division and differentiation. A more complete understanding of the genetic and molecular controls of these processes may yield information about how such diseases arise and suggest new strategies...

...preventable diseases. They are caused by various factors which may include diabetes, high blood pressure, high cholesterol levels, smoking cigarettes, obesity and overweight. These diseases are controllable by one managing their own lifestyles and living a healthy life. The issue being looked in this context is to reduce the community health problems. (Kvan, 2008) The goal of the nursing assessments is to improve the various health care systems in various communities and hence improve the quality of life. This is done through treatment of risk factors which cause heart diseases. The only hope about heart diseases and stroke is that, an early detection of any cardiovascular diseases can be easily treated. The community development programs prevent the reoccurrence of repeated cardiovascular diseases.(Lloyd, 2010) However, this is not an easy task. First, controlling the factors which majorly contribute to stroke and heart diseases is posing a great challenge to medical practitioners. For example, cholesterol levels in cardiovascular system leads to high blood pressure. It is one of the major...
