Human heart

States. Each year approximately 600,000 people die from these heart related diseases. Cardiovascular disease is something that can be acquired at birth or over a period of time due to genetics or lifestyle. There hundreds of different types of cardiovascular disease. Cardiovascular disease can be detected through a series of blood test, blood pressure, or even an electrocardiograph. Electrocardiographs record the electrical activity of the heart. The main purpose of this essay is to inform the…

For example the bones in the skull protect the brain from damage and the rib cage protects the lungs and the heart. This is due to the thickness and strength of the bones muscle and tissue that surround the organs. Without this protection the body would be at risk of serious injury to its major…

the human chest is an organ about the size of a fist, commonly referred to as the heart. Responsible for pumping blood throughout the entire body, the heart is essentially the life force of mankind. For reasons such as natural causes, generational inheritance, or over exertion, people can have an abnormal heart rhythm. Dr. Michel Mirowski studied arrhythmias and the first Implantable Cardioverter Defibrillator (ICD) was used in 1980. “ICDs are for people who have had an abnormal, fast heart…

Humans become sick for many reasons. Poor eating habits, lack of exercise, and stress can lead to illness. Stress and worry can wear the human body down. “Worried Sick” by: Nortin M. Hadler, M.D., describes the effects of unhealthy habits, cancers, and cardiovascular disorders of octogenarians have changed over the course years. The human species are expected to live approximately to the age of eighty-five. Unfortunately not every person will live to see their eighty-fifth birthday. The human…

isolated heart from normal rats following acute MI Juea Park INTRODUCTION The heart is a muscular oragn which has to perform work to eject blood for the right and left entricles. Two laws govern the relationship between ventricular volume and cardiac pump performance. The first, the law of Laplace, is a low stating that when the ventricle dilates, the wall stress needed to achieve a give intraventricular pressure is increased. The second, Starling’s law of the heart,…

Extended Response-Organ Transplants Part A Heart transplants are only available to those who have end stage heart disease and have tried all other options. It can also only be obtained by someone who has an expected life of at least 5 years post-transplant and who can potentially return to an active life. Anyone who suffers from cardiogenic shock, intractable symptomatic heart failure which cannot be treated, requires permanent mechanical cardiac support, has frequent discharges from an AICD or…

Introduction: The heart plays a crucial role in the human circulatory system. The large organ pumps the blood through arteries, veins, and capillaries to distribute oxygen and nutrients to the body. The circulatory system also plays a part in removing our waste products. Humans have double circulation, meaning the blood passes through the heart twice before completing one round; this allows for the blood to be “re-pressurized”. Once the right side of the heart receives blood from the body,…

During exercise or human movement, a person’s heart rate, the number of beats per minute, and also systolic blood pressure increases as the intensity of the exercise increases. While diastolic blood pressure will remain the same with the exception of a 10-mmHg gap change. A typical person’s blood pressure remains around 120/80 millimeters of mercury (mmHg). It may not be the exact numbers but it is very similar to the standard. During a type of exercise a person’s systolic blood pressure, “the…

term memory loss. Stress can lead to hair loss or even balding, which mainly is our own fault due to poor diet and health. Stress can ruin your teeth, People tend to grind their teeth more when they are stressed out. Stress can physically damage your heart muscles. Stress can make you age faster by not letting telomeres (structures on the end of chromosomes) grow at a normal speed, which leads to the signs of ageing: wrinkles, poor eye sight, weak muscles, and more. (A.D.A.M;…

Population of the United States The World Heart Federation (2012) defines Cardiovascular Disease (CVD) as “a broad range of diseases that affect the heart and blood vessels” (n.p.). CVD is also known as Heart Disease (American Heart Association [AHA], 2015). According to Roger, Lloyd-Jones, Berry, et al. (2011) there are numerous types of cardiovascular diseases including: hypertension, coronary artery disease, congenital cardiovascular defects, stroke, congestive heart failure, atherosclerosis…
