Beating Heart

In today’s world, one of the leading causes of death in most of the developed countries is heart disease. Unfortunately, the number of cases is rising steadily because of both present- day lifestyles and increased overall longevity. While it’s developing, it can have a disastrous impact on the life of the inflicted. Modern medicine, though, has established many effective treatments for heart disease. They range from drugs and lifestyle changes to surgery. Of course, overall prevention is better…

narrow the arteries, which makes it more difficult for blood to pass through. This causes hypertension. The heart has to work harder to pump the blood through the narrowed arteries. If the coronary arteries become narrowed coronary artery disease occurs. The coronary arteries supply the heart muscle with blood. When blood is restricted to the heart chronic heart failure can occur. The heart cells become deprived of oxygen and die. C.M is taking atorvastatin to lower his LDL levels and…

with approximately 600,000 deaths in the U.S. only. One of the major difficulties with heart diseases is the heart’s failure to produce new and healthy cells in a timely manner. Unfortunately, the heart lacks the ability to quickly generate new tissue composed of viable cells, leading to patient death. Cardiovascular progenitor cells (CVPCs) are believed to be highly useful in cell-dependent therapy aimed at heart diseases. CVPCs are quite similar to stem cells in that they will eventually…

important portion of the body. When people think of muscles, they usually think first of voluntary movement, but that is only part of the story. Muscles are literally everywhere in the body. Throughout the body, there are muscles in the eye, heart, limbs, tongue, throat,…

The first is called an echocardiogram. This will send sounds waves that will show moving images of the beating heart. While I waited for the results on this test, I also decided to run an ECG or electrocardiogram. This will detect any abnormal rhythms of the heart by showing its electrical patterns. I checked the results of both and both showed very interesting results. The ECG showed that the heart had a strong arrhymia. The echocardiogram showed that the ventricular septal defect was worse…

taurine and ginseng) intended to increase the drinker 's energy”. Although energy drinks can be a benefit when providing energy to the body, there are also negative effects. Like any other regular caffeine and sugar, it stimulates blood pressure and heart rate. At the moderate daily intakes, the human body can take up to 300 to 400 milligrams of caffeine, which is the amount equals to four cups of coffee (Roberts). However, some energy drinks contain up to 505 milligrams of caffeine (Roberts).…

The heart is the organ that pumps blood through the body. Together with the circulatory system it makes up the cardiovascular system (Anatomy of the Heart, 2015). The heart is oddly shaped, almost oval at the bottom but with a series of veins and arteries at the top and sides. It definitely is not “heart” shaped. It is made up of four chambers consisting of two atria (upper) and two ventricles (lower). These chambers are separated into right and left side by the septum, which is a wall of muscle…

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 blood to backflow into the atrium when ventricle contracted. This condition can be the result of valvular insufficiency. This occurs when one of the heart valve leaks because the cusps do not close tightly enough. It can caused by inflammation in the heart…

For over 55 years, humans have been flying in space. With an understanding of evolution, it has always been assumed that human bodies have adapted to the gravitational force found here on Earth. The space station and the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards…

place him or her on life support to continue biological functions. This option creates an issue in making family members accept the reality that their loved one has passed away. There are some “religions [that] define life as breathing lungs and a beating heart,” even if it is artificially done by machines (Wang 2). As a result, a cruel, false hope is then given to…
