An artery is an elastic blood vessel that transports blood away from the heart. There are two main types of arteries: pulmonary arteries and systemic arteries. Pulmonary arteries carry blood from the heart to the lungs where the blood picks up oxygen. The oxygen rich blood is then returned to the heart via the pulmonary veins. Systemic arteries deliver blood to the rest of the body. The aorta is the main systemic artery and the largest artery of the body. It originates from the heart and branches
scientists thought he died in the cold up the mountain, some had doubts, and while studying the remains of the mummy, an anomaly was found inside of it. An arrowhead had been found lodged in his back, close to the heart and deep enough to puncture an artery. As the Huffington Post says “ Clearly, the arrowhead had caused a one-centimeter gash
chest pains, known as angina (Matthews, 2005). CHD is primarily due to atherosclerosis, which is the blockage of blood flow in the arteries due to the accumulation of fats, cholesterol, calcium and other substances found in the blood. Atherosclerosis takes place over many years, but when the blood flow becomes so limited due to the build up of plaque in the arteries, there becomes a serious problem. “When... ... middle of paper ... ...itive, and clinical neuroscience.

Stab in the Heart A stab in the heart by one’s own hopes is truly the cruelest way to leave this world. Sadly, that is exactly what happen to Sarah Cole in Russell Banks’ short story entitled, “Sarah Cole: A Type of Love Story.” The man who dated Sarah for a short period of time tells the tale. He calls himself Ron, for Ron could have been him, but he doesn’t want to say who he is for fear of looking cruel. He wants to believe what he did was right when he left her. They both didn’t handle their
the meaning of high blood pressure. It is known as the “silent killer” because it does not create any symptoms. The most common reason for high blood pressure is arteriosclerosis. Arteriosclerosis is the thickening and hardening of the walls of the arteries, occurring in old age. Four control systems have a job in maintaining blood pressure. These are the arterial baroreceptor and chemoreceptors’ system, regulation of body fluid volume, the renin- angiotensin system, and vascular autoregulation. Primary
for one in four deaths every year, about 600,000 mortalities. This disease affects men and women, as well as every ethnic group. Coronary artery disease is the most common cardiovascular disease, representing approximately 400,000 deaths per year of the aforementioned 600,000 total deaths from cardiovascular diseases as a whole. In 2010 alone, coronary artery disease cost the United States $108.9 billion for health care services, medication, and lost productivity. These chilling statistics, published
disease is also known as cardiovascular disease. Since there are many conditions related with heart disease. The most common types are coronary artery disease or damage in the heart’s major blood vessels, stroke or damage to the brain from interruption of its blood supply, and high blood pressure or a condition in which the force of the blood against the artery walls in too high. These conditions may lead to a heart attack. (mayo). Statistics (2) Heart disease is considered a man’s disease
Page 2 Vicki is a 42 year-old African American woman who was recently diagnosed with hypertension. Hypertension, also know as high blood pressure is the force of blood pushing against the arteries as it flows through them. Arteries are the blood vessels that carry the oxygenated blood from the heart to the rest of the body’s tissues. One of the main reasons hypertension can be so dangerous is because you may not even know you’re suffering from it, in fact, nearly one-third of patients suffering
Currently, John Martin is at high risk for a heart attack within the next 10 years. His blood pressure is high, HDL is low, and he is a smoker. While it has been determined that Mr. Martin does not have metabolic syndrome, it is imperative that he make the following changes in order to ensure a long, healthy life. John Martin’s systolic blood pressure was recorded at 148 mm/Hg, a borderline high number. An optimal systolic blood pressure is 120 mm/Hg for adults. Currently, Mr. Martin is in the
read as the top number of blood pressure. Diastolic pressure is the pressure in the arteries while the ventricles are filling in between heart beats and is read as the bottom number. A normal blood pressure readings is a systolic number between 90-120 and a diastolic pressure between 60-80 (Kenney, Wilmore, & Costill, 2015). When a person exercises, the active tissues in the body
Medicine is the applied science or practice of the diagnosis, treatment, and prevention of disease. Many people from all different cultures have made vast contributions to the medical field. This has been a field of study throughout history. Early day practices laid the ground work for were we are today in the medical field especially during The Renascence. One man to lay ground work into the medical field was a surgeon Ambroise Pare. He would get his start as an apprentice barber surgeon. It was
group of methods in which diagnostic testing and non-surgical interventional treatments are used for treating patients who suffer from various heart diseases and disorders such as atherosclerosis (hardening of artery walls) and coronary artery disease (plaque build-up in coronary arteries). This field covers a variety of therapies ranging from stents to intravascular ultrasounds. Invasive and interventional cardiology began with the birth of catheterization, starting from the early ancient Egyptians
I. Introduction When I hear the words ”bad foods”, I always think of cakes, muffins, ice-cream and so on. But there is something that is almost always there, but it is often hiding. We put it on our fries, on nearly every single protein, and we use it when we boil water. Have you guessed what it is? Salt. It is always there, but we might not always know that it is there (Farley). It is one of those things that we don’t always see, but will affect us in the long run. But why is it that our parents
Muscular system is a system which consists of specialized cells which called as muscle fibers. The main function of muscular system are allows the body movement, circulates the blood throughout the body, helps to maintain the posture such as standing and sitting and also function as heat production which helps to maintain the body temperature. Human body would not able to move at all without muscles. In human body there are more than 600 muscles and most of the muscles attached to the skeleton. Muscle
1.2 & 1.3 Explain The Cardiac Cycle And Describe How The Heart Rate Is Modified According To The Needs Of The Body When a muscle contracts and relaxes without receiving signals from nerves it is known as myogenic. In the human body, the cardiac muscle is myogenic as this configuration of contractions controls the heartbeat. Within the wall of the right atrium is the sino-atrial node (SAN), which is where the process of the heartbeat begins. It directs consistent waves of electrical activity to the
Even though we all know that we cannot exist without oxygen, most of us do not realize how important the amount of oxygen is to our heart rhythm and our heart rate. When we are anxious and worried due to physical, emotional or spiritual pain and stress, we tend to breathe more quickly and shallowly than when we are relaxed. Our heart rate variance becomes super chaotic and incoherent, affecting the quality of our brain function.[] Oxygen is the main energy source for brain functioning. If the stress
Concepts of Lifetime Fitness Homeostasis is the state of equilibrium in which the internal environment of the human body remains relatively constant. Two excellent examples of homeostasis are how the body maintains a constant temperature and blood pressure during strenuous physical activity or exercise. Although there are many other activities in the body that display homeostasis, I will only discuss these two. Temperature in the human body is usually kept at approximately 37 degrees
From the subjective data collected through history taking and objective data gathered from the physical assessment of Mr Jones, the primary differential diagnosis was AR. During auscultation, the murmur of aortic regurgitation is complicated. The left ventricle is typically dilated secondary to extreme volume overload, as it must handle both the forward flow delivered from the left atria as well as the backflow of blood from the aorta. As the damage progresses, the symptoms can appear suddenly
cholesterol) leading to increased risk of arterial occlusion, high amounts of saturated fats leading to an increased risk of elevated LDL cholesterol, high amounts of trans fats leading to higher chances of clogged arteries, ventricular fibrillation, and atherosclerosis of the arteries. The risk factors for MI include, but are not limited to, hypertension leading to increased risk of heart complications, high LDL cholesterol leading to atherosclerosis, high levels of triglyceride fats leading to
The American Heart Association is a charity that helps anyone dealing with cardiovascular disease. The charity was founded back 103 years ago in New York city by individuals who were worried about the lives of the people affected by cardiovascular disease. During the 1910s heart disease was considered a deadly disease, most patients were put to bed rest. Now thanks to the advancements in science there is a high chance of survivors. We should support and donate a million dollars to The American Heart
