...Heart Essay When a performer starts to exercise, they inevitably increase rate of respiration, meaning they require more glucose and oxygen (if aerobic) and need to primarily remove more carbon dioxide as well as lactic acid (if anaerobic). The first way this is done is by secretion of the hormone adrenaline into the bloodstream. Adrenaline in blood is picked up by chemoreceptors in the aortic arch, impulses are then sent to cardiac control centre (in the medulla oblongata) via sympathic nerve which increases heart rate. Adrenaline (epinephrine) facilitates greater cardiac output, meaning a greater volume of blood pumped into the systemic circuit, carrying more oxyhaemoglobin. Adrenal gland also secrets norepinephrine (a different hormone), which causes the blood vessels to constrict (narrowing of lumens) the increases blood pressure. When the cardiac control centre in the medulla oblongata receives nerve impulses it sends a nerve impulse to the SA (Sino-Atrial) Node, which sends the wave excitation across both atria causing atrial muscles to contract (atrial systole) forcing blood through bicuspid and tricuspid valves. The wave of excitation (electrical impulse) hits the AV (atrio-ventricular) Node. This sends the wave down the septum through the bundle of his and purkinje fibers, which then hits apex of the heart and spreads round ventricle muscular walls causing them contract. This is called ventricular systole, causing bottom to top contraction forcing blood into arteries...

...THE RELATIONSHIP BETWEEN EXERCISE AND HEART RATE AS WELL AS EXERCISE AND BLOOD PRESSURE PHYSIOLOGY ESSAY/ ERGONOMICS LABROTARY WRITE-UP Submitted in partial fulfilment of requirements for the Course Human Kinetics and Ergonomics 102. Department of Human Kinetics and Ergonomics INTRODUCTION When the metabolic motion of skeletal muscles increases, the flexibility of the heart can be detected throughout the exercise (Okutucu et al., 2010). The heart and blood vessels make up the cardiovascular system, which respond to exercise with an increase in heart rate and strength of reduction with each heartbeat, causing a higher cardiac output (amount of blood pumped through the heart per minute) and blood pressure (Okutucu et al., 2010). This report presents an assessment of “exercising” blood pressure and heart rate. The aim of this assessment was to obtain an understanding of how heart rate and blood pressure respond to submaximal exercise of the same intensity. The hypothesis tested was what impact exercise had on blood pressure and heart rate. The purpose of assessment of “exercising” heart rate was to measure heart rate while exercising at a submaximal intensity as well as to measure recovery heart rate following submaximal exercise. The purpose of assessment of “exercising” blood pressure was to measure blood pressure while exercising at a submaximal intensity and to measure recovery blood pressure following submaximal exercise. This report presents the procedures...

...accidents. This essay views sleep and sleep deprivation from five different motivational perspectives in order to gain a holistic understanding of the phenomena. From evolutionary, psychodynamic, behaviourist, cognitive, and hierarchy of needs perspectives, it is inferred that the cognitive and behaviourist perspectives uphold the most merit for gaining understanding into sleep and sleep deprivation. However, it is concluded that in order to obtain the greatest comprehension of the phenomena, the implementation of all motivational perspectives is required. Sleep is one of the most fundamental components of a healthy existence. The phenomenon of sleep deprivation, resulting either from lifestyle choices or the undertreatment of sleep related illnesses, could be a factor for a multitude of health disorders prevalent in today’s society (Nature, 2005). It is suggested that people of industrialized countries obtain about 20% less sleep today than they did a century ago. Sleep deprivation has been linked to Type 2 diabetes, obesity, and has also been found to significantly increase the chance of a motor-vehicle accident (Wilson, 2005). In order to address the problem of sleep deprivation, it is imperative that the motivation behind sleep and sleep deprivation is understood. This essay will look at sleep and sleep deprivation through five different perspectives of motivation: evolutionary, psychodynamic, behaviourist, cognitive, and hierarchy of needs. This essay will then argue that...

...Sepsis An Overview Health And Social Care Essay ukessays.com /essays/health-and-social-care/sepsis-an-overview-health-and-social-careessay.php Sepsis is an infection of the bloodstream. The infection tends to spread quickly and often is difficult to recognize. One of our roles as a nurse is that of patient advocate, and as such we are closest to the patient, placing us in a key position to identify any subtle changes at their earliest onset and prevent the spread of severe infection. Knowledge of the signs and symptoms of SIRS, sepsis, and septic shock is key to early recognition. Early recognition allows for appropriate treatment to begin sooner, decreasing the likelihood of septic shock and life-threatening organ failure. Once sepsis is diagnosed, early and aggressive treatment can begin, which greatly reduces mortality rates associated with sepsis. sep•sis (ˈsep-səs) n. Sometimes called blood poisoning, sepsis is the body's often deadly response to infection or injury (Merriam-Webster, 2011) Sepsis is a potentially life-threatening condition caused by the immune system's reaction to an infection; it is the leading cause of death in intensive care units (Mayo Clinic Staff, Mayo Clinic 2010). It is defined by the presence of 2 or more SIRS (systemic inflammatory response syndrome) criteria in the setting of a documented or presumed infection (Rivers, McIntyre, Morro, Rivers, 2005 pg 1054). Chemicals that are released into the blood to fight infection trigger widespread inflammation...

ISBN 978-0-692-00528-6 Editors: Mark S. Kovacs, Todd S. Ellenbecker, W. Ben Kibler TENNIS RECOVERY A Comprehensive Review of the Research A United States Tennis Association Sport Science Committee Project Editors: Mark S. Kovacs, PhD Todd S. Ellenbecker, DPT W. Ben Kibler, MD Introduction In the last two decades, physical training and competitive opportunities have increased dramatically in junior, collegiate and professional tennis. This arose due to a multitude of factors, but much of it has stemmed from an increase in knowledge and understanding of scientifically based training programs focused on improving performance. As this focus on performance has increased, the area of recovery has received relatively limited focus. Recovery is a multi-faceted paradigm focusing on recovery from training—session to session, day to day and week to week. Recovery is also vitally important during training as well as in competition between matches and between days during multi-day tournaments. As more information is needed in the area of tennis specific recovery, the Sport Science Committee of the United States Tennis Association (USTA) sponsored an extensive evidence-based...

...India of my dreams is a place where there’s an IIT for every Harvard and a Narayan Murthy for every Bill Gates. Where youngsters don’t hop aboard a plane to US for their dream job, rather stay back in their homeland and work for its welfare. An India, where those not related by blood are united by beliefs. By their love & not separated by faith or color; where it’s not a crime to wed out of ones community, where millions aren’t stashed in Swiss accounts rather with every individual. India of my dreams is such a place where each Indian truly believes that ,”Saare Jahan Se Achha Hindustan Humara.” “Be proud that you are an Indian, proudly claim I am an INDIAN”, these are the words of Swami Vivekananda. India-my motherland, with its mighty Himalayas looks like a golden bird flying high all above the sky with its cultures, traditions and with many advanced developments in science and technology. I am very proud to be an Indian. I love my country and I want to be the best in the world. I wish that my country should become a great nation with its talent and capability. I have a sweet little dream for my motherland. People in India should be self-sufficient in food for which we have to make the barren lands productive. New varieties of seeds and modern tools should be used for agriculture which is the backbone of Indian economy. The India of my dreams is a corruption-free nation. Beggary should be abolished; government should be people-friendly and citizens should...

Use a black or blue pen. • Remember to complete the submission information on every page you turn in. Multiple-Choice Questions (1 hour) Section 1 consists of selections from prose works and questions about their content, form, and style. Questions 1-10. Read the following passage, from "The Yellow Wallpaper," by Charlote Perkins Gilman (1899) carefully before you choose your answers. You may refer to the passage as often as necessary while answering the questions. It is very seldom that mere ordinary people like John and myself secure ancestral halls for the summer. A colonial mansion, a hereditary estate, I would say a haunted house and reach the height of romantic felicity—but that would be asking too much of fate! Still I will proudly declare that there is something queer about it. Else, why should it be let so cheaply? And why have stood so long untenanted? John laughs at me, of course, but one expects that in marriage. John is practical in the extreme. He has no patience with faith, an intense horror of superstition, and he scoffs openly at any talk of things not to be felt and seen and put down in figures. John is a physician, and perhaps—(I would not say it to a living soul, of course, but this is dead paper and a great relief to my mind)—perhaps...
