  • Congestive Heart Failure

    Congestive Heart Failure Heart failure is a progressive and chronic condition that occurs when the heart muscle is weak and unable to pump adequate blood in order to meet the need of the body for blood and oxygen (AHA, 2014). There are two types of Heart failure namely Left sided and right sided heart failure. According to Moore & Roth (2015), left-sided heart failure occurs when the left ventricle failed to pump proficiently. It prevents the body from receiving adequate oxygen-rich blood. The blood backs up into the lungs causing fluid to build up and causes shortness of breath. ventricular septal defect cardiomyopathy, anterior myocardial infarction cardiac tamponade, etc. are causes of left-sided heart failure. Right-sided heart failure…

  • Athletic Heart Syndrome Analysis

    expected, alterations to the left ventricle are associated with athletic training. LV enlargement and increased wall thickness are typical findings among athletes. In endurance training, LV remodeling results in eccentric hypertrophy, which is an increase chamber dimension with an increase in wall thickness. Strength training results in concentric hypertrophy of the left ventricle which is described as thick walls with none or slight dilatation. Out of the two, concentric LVH is more common…

  • The Geriatric Cardiovascular System

    Data regarding the cardiovascular system of older adults is slightly limited, due to the fact that older people are usually not included in clinical trials. However, enough research has been done to identify common physiological changes in the geriatric cardiovascular system, such as: increased heart weight; decreased number of myocardial cells with enlargement of remaining cells; increased left ventricle wall thickness; increased arterial stiffness; increased elastin levels; increased collagen…

  • Electrocardiogram Lab

    The chambers include the right and left atrium as well as the right and left ventricle. The atrium receives blood from the venous system while the ventricles pump blood into the arterial system. These pumps are able to provide circulation out to the pulmonary (right pump) and systemic system (left pump). When conducting this lab experiment, it is important to be familiar with an electrocardiogram. An electrocardiogram measures the electrical activity of the heart. The electrocardiogram displays…

  • The Importance Of Exercise In The Human Body

    The decreased in resistance is caused by vasodilation done by specific metabolites like AMP, H+, and K+. Consequently, an increase in blood flow accords with a higher cardiac output that is determined by heart rate and stroke volume. At high work rate, cardiac output (amount of blood pumped by the heart per minute) composed by the product of stroke volume (amount of blood ejected from the left ventricle per beat) and heart rate can reach up to 90% of theoretical maximum value as well as having…

  • Ventricles Case Study

    1. Based on the information provided, the left atrium and left ventricle are not working properly due to mitral valve not working appropriately. The reason this set of valves was chosen is because in the passage, it stated that the X-Ray show an enlargement in the left atrium and left ventricle. This happen is due to inefficient cycle of blood resulting in abnormal heart sound or heart murmur. Mitral valve of the left side is misshape and less flexible. Mitral valve has a leakage and allows…

  • Mechanical Ventilation Research Paper

    affects of PEEP that can alter the left ventricular function according to Cairo (2012). An example of this is when the heart and aorta compress due to positive pleural pressure. Vascular pressure also increases while the left ventricular afterload decreases. Therefore, the reaction is not always stable and cardiac tamponade, as a result of PEEP, can have a negative impact. This impact can change myocardial compliance. When a patient is on PPV the pulmonary capillaries are stretched or…

  • Animal Physiology Lab Report

    Introduction: The heart rate of an animal can be used as an indicator to identify when a stimulus evokes a reaction from the animal. Specifically in the case of humans’, there tends to be the cognitive ability to physically withhold a reaction from a stimulus and mask the involuntary reaction. However, the heart rate reacts immediately after a stimulus, and is not reigned in or controlled cognitively, so could the heart potentially be a true indicator of an individuals reaction to a stimulus?…

  • Physiology: A Case Study Of Poiseuille's Equation

    2. Physiology Q=(P1 - P2)/ R Q= flow The amount of a liquid moving past a point in a given amount of time. P=Pressure (P1-P2) The amount of force placed on an artery at any given point in time. R= resistance Is the force that must be overcome for flow to occur. Describe the basic flow equation and resistance equation as they relate to vascular flow. b. Define Poiseuille’s Equation, and describe the effect on blood flow of a change in each variable. Poiseuille's equation states that the…
