  • Hypertrophy Essay

    the muscles in their bodies. Cardiac myocytes use growth signals from wall stress to increase thickness and normalize systolic pressure; this physiological condition is known as Left Ventricular Hypertrophy (LVH) because of its effect on the left ventricle which pumps oxygenated blood to the muscles. Hypertrophy of cardiac muscles becomes deleterious when the muscles can no longer beat in sync causing fibrillations or arrhythmias or when the muscles thicken to the point of constricting or…

    ventricular mass as well as impaired cardiac compliance. This reduces the upright stroke volume and the intolerance to orthostatic (Gielen et al., 2010). The converse is true for individuals who do not exercise regularly. This maintains the normal left ventricle contractile function through prevention of cardiac pathologies that are associated with ageing (Fleg & Strait, 2012). Regular exercise also results into cardiac adaptation thus the athlete’s heart; a physiological cardiac hypertrophy…

  • Causes Of Left Heart Failure

    Heart failure is a common killer of both men and women in the United States every year. It is a very serious issue that plagues this country and other developed countries like it. Heart failure is a syndrome with many risk factors, such as, age, obesity, congenital heart diseases, and many others. A client is considered to be in heart failure, when their heart is unable to profuse tissues in the body with oxygenated and nutrient rich blood for tissue to sufficiently function. A client when…

    replenished by the food ingested. In the right ventricle, impurities in the blood were expelled into the pulmonary artery and then exhaled from the lungs. While purified blood went to the left ventricle through invisible pores in the interventricular septum and combined with pneuma that came from the pulmonary veins to cool down the body. Subsequently, the mixture of pnuema and the small amount of blood traveled to the pulmonary arteries. The left ventricle…

    the right ventricle. The tricuspid valve then closes when the ventricles is full then the right ventricle contracts, sending the blood to the pulmonary artery. From the pulmonary artery the blood goes to the lung and get oxygenated. The oxygenated blood, then flows into the left atrium through the pulmonary vein. Then the mitral valve opens up and the blood goes into the left ventricle. When the left ventricle is full the mitral valve closes and the ventricle contract. The left ventricle is the…

  • Difference Between The Heart And Pig Heart

    is thicker than that of the right side. • Right side circulates the deoxygenated blood while the left side circulates oxygenated blood. • Right atrium receives blood from tissues and organs, and right ventricle pumps it to lungs. However, the left atrium receives blood from lungs and left ventricle pumps it to the rest of the body. • Superior vena cava and inferior vena cava bring blood to right side of the heart but only pulmonary vein brings blood to left…

  • Pulse Pressure Essay

    D. PULSE PRESSURE INTRODUCTION The pulse pressure is the difference between the systolic and diastolic pressure. The systolic or top pressure is defined as the amount of pressure exerted on the blood vessels when the ventricle is contract (systole). The pressure is due to the force produced as the blood is ejected contacted with the blood vessel’s wall. On the other hand, the diastolic or bottom pressure is defined as the amount of pressure of the blood vessels when the heart is at rest…

  • Acute Heart Failure

    Reduced cardiac output from the left atrium and ventricle are termed Left-sided heart failure whereas right sided heart failure involves the right atrium or ventricle which occurs in isolation most commonly due to cor pulmonale in conditions such as COPD. Biventricular failure is when both sides of the heart have diminished output and may happen in patients who have left-sided heart failure to begin with or any pathology affecting both ventricles. Other types of heart failure include forward…

  • Frog Lab Report

    by the decreasing number of gap junctions along the pathway of conduction which creates a resistance against the conduction of excitatory ions, i.e. Ca2+, from one fibre to another. This ensures that the atria completely empty the blood into the ventricles before ventricular contraction occurs. 3. A typical electrocardiogram (ECG) usually shows P, Q, R,…

  • P Wave Deflection

    the R wave is the first upward deflection after that. Anyone can easily recognize it on the electrocardiogram (ECG). That is because it is the largest one out of all the waveforms. The R wave corresponds to the depolarization of the left and right ventricles. It does not need the Q wave to be the first deflection at all. Also, note that there can be multiple R waves. Throughout the paper, it will discuss all the wave functions, specifically the R wave, any abnormalities and how every waveform…
