Valvular heart disease

The heart tends to become a bit larger, since it becomes a bit larger the amount of blood it can hold declines. A older heart can still supply adequate blood to all body parts, but when it has to work hard it may not be able to supply as well as it could in the past. All individuals can benefit from regular exercise. Exercise in older adults can help reduce the impact of illness and chronic diseases. The reason exercise can seem to reverse aging is…

Albanese’s Transnational Crime and the 21st century and Naim’s Illicit, discuss gun smuggling, human organ smuggling, and stolen property smuggling. From previous readings, we know that crimes such as these advance due to the fall of the Soviet Union, globalization, and even the advancement of technology. For each of these crimes, the authors elaborated on the type of harms that occurred, the benefits for those involved with these crimes, the challenges that are faced when trying to prevent…

poisonous gas that is instantly absorbed into the blood replacing oxygen. Due to this, the heart has to work harder to get the approximate amount of oxygen to the muscles, brain, heart and other organs. When nicotine is breathed in by the individual, it only takes about ten seconds for it to reach the brain. Nicotine leads to an increase in heart rate and blood pressure. Not only does it affect the brain and heart, it also affects the respiratory system, as well. Due to this, individuals who…

The disease I chose for my project is the disease heart attack, also called myocardial infection. A heart attack is when the heart cannot receive oxygen and the muscle begins to die. In scientific ways, a heart attack is when a “heart attack occurs and when the flow of blood to the heart is blocked, most often by a build-up of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries). The interrupted blood flow can damage or destroy part…

Tim O’Brien’s novel The Things They Carried, comprises twenty-two individual fictional war stories. Although a war novel, the stories don’t focus on guns, grenades, blood, or gore. It focuses on the “human heart.” O’Brien’s novel teaches us that the “human heart” is fragile and the negative impacts of war can break it. Innocence and life are effected in return. Young men enter the war clenching onto they innocence. Unknowingly, they will be stripped from it. Mary Anne Bell—a significant…

premature atrial complex. I remember this as “aberrant, randomly present”. There are three hearts blocks that you must differentiate through their similarities. A first-degree heart block, has a p-wave that measure longer through each complex. I remember this as “long, longer, drop”. The second-degree heart block, has two p-waves per complex with equal measurements, it’s the “twin block”. The third-degree heart block is a fatal rhythm it will have non-correlating and multiple p-waves through…

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,…

Effect of studying systems of Fetal pig Purpose The purpose of this pig dissection lab is to organize the body sturcture by observing external anatomy, oral cavity, neck, superficial muscles, thoracic cavity, abdominal cavity, and both male and female reproductive systems. By studying the systems of the pig, it helps understand the systems of the humans because humans and pigs are both mammals which we can assume that systems of pig and human are similar. Results The sex of pig was able to…

Gas Exchange Gas exchange is the process in which gases enter and leave a body by diffusion across gas exchange surfaces. Gas exchange is important as it transfers oxygen from surroundings of an organism to individual cells in the organism’s body, needed by the cells for respiration to occur. Carbon dioxide is released. This process produces energy which is essential to an organism for survival. Group 1 – Insects The definition of an insect is any of a group of small and often winged animals…

According to the National Heart, Lungs and Blood Institute (NIH) (2014) atrial fibrillation ( Afib) is a heart arrhythmia which affects the rate and rhythm of the heartbeat. Atrial fibrillation causes the heart to contract very fast and irregular, which result in blood pooling in the atria. Atrial fibrillation affects the cardiac system and the respiratory systems drastically because the heart may not be able to pump enough blood to the lungs and body, thus…
