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…

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…

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 of the heart muscle.” (Cliff…

disease (CAD) or coronary heart disease (CHD) related deaths stands as one of Healthy People 2020’s objectives to improve the health of Americans (Office of Disease Prevention and Health Promotion [ODPHP], 2014b). Healthy People 2020, a program from the Office of Disease Prevention and Health Promotion (ODPHP), focuses on targeting health concerns in the United States. Healthy People 2010’s objective to decrease CAD related deaths was successful; however, the prevalence of heart disease remains…

121,956 COPD patients with the age range from 45 to 80-years old who were also receiving the BB treatment. Of the 15 studies, 5 studies included only COPD patients with concomitant coronary heart disease (CHD) including angina pectoris and MI and the other 3 studies evaluated only COPD patients with the heart failure (HF). The duration of the treatment among studied participants ranged from 1 year to 7.2 years.1 The researchers observed that the BB use was associated with the significantly…

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…
