Demonstrate the role of stents in Percutaneous Coronary Intervention (coronary angioplasty) Introduction The heart is a pump that circulates blood to the rest of the human body. It is positioned at the centre of the chest, just between the lungs. The network of blood vessels that branch over the surface of the heart are the coronary arteries.…
Protection- The cardiovascular system is responsible for the protection of our body by forming white blood cells or Leucocytes or White Blood Corpuscles. WBC’s helps in fighting against the…
The heart contains major coronary vessels on the surface. The location of it helps to supply oxygen to different areas of the heart. Since they are on the surface the heart's efficiency increases as it decreases other potential problems. However, if these vessels were located inside of the heart it may result in a decrease in strength of the heart's wall. The vessel's location on the surface has its advantages…
The right atrium gets blood from the systemic circuit and passes it to the right ventricle and it pumps blood to the pulmonary circuit. The left atrium collects blood from the pulmonary circuit and empties it into the left ventricle which then pumps blood into the systemic circuit. 39. Pericardial inflammation results in a production of pericardial fluid. The fluid builds u in the pericardial cavity, which restricts movement of the heart, and this is known as cardiac tamponade.…
Then, the right atrium then the right ventricle and leaves through the pulmonary arteries to the lungs. Oxygenated blood enters into the pulmonary veins from the lungs and enters the left atrium and the left ventricle then it leaves through the aorta then travels to the rest of the body. In the heart beat there is sinoatrial nodes, atrioventricular nodes, bundles of his, and perkinje fibers. Sinoatrial nodes are a small muscle in the heart that produces some kind of signal. Atrioventricular nodes act as a relay station that controls the heart rate.…
About the size of a large fist, heart is made up of cardiac muscle, myocardium, with skeletal muscle-like striations. It has two upper atria & two lower ventricles separated vertically by septum, and four main valves with which the blood makes its directional flow into and out of the heart. Deoxygentated blood with which the blood flows into and out of the organ. Deoxygenated blood enters through the venae cava fills the right atrium (RA) and right ventricle (RV) through the tricuspid valve. Then, RV contracts pushing the blood to pulmonary circuit and returns oxygenated from the lungs and travels to left atrium (LA) and left atrium (LA) through the mitral valve.…
• Superior vena cava and inferior vena cava bring blood to right side of the heart but only pulmonary vein brings blood to left…
We continue through the external iliac vein and right into the inferior vena cava! We are now in the right side of the heart, literally, the right atrium. The SA node’s action potential fires again and through the tricuspid valve we go. We’re now in the right ventricle. This one is roomy like the left so we have to wait with the AV node until the ventricle fills up some more.…
When the right atrium contract the blood flows through the tricuspid valve and into the right ventricle. When the right ventricle contracts the blood passes the pulmonary semilunar valve, into the pulmonary artery, and the blood is going to the lungs. The blood goes through a process in the lungs and the blood become oxygenated. The oxygenated blood is returned to the heart from the pulmonary vein and goes into the left atrium. When that atrium contracts the blood asses the mitral (bicuspid) valve and goes to the left ventricle.…
The right side of the heart picks up oxygen by moving blood to the lungs. The oxygen-rich blood then goes to the left side of the heart. The left side of the heart then moves it to the aorta; the main artery that transports oxygen-rich blood to the body (“Ventricular Septal Defect (VSD)”). VSD causes the person’s…
In order to understand exactly what Left Ventricular Hypertrophy is, it is important to be able to break down the word. The prefix Hyper- means over or more, and the suffix -trophy means well-fed. Therefore, LVH is the thickening and/ or the enlargement of the left ventricle. Under normal conditions, the left ventricle of the heart is responsible for the big push that sends blood through the aorta and to the rest of the body (Sheir 2015, p.560). When the left ventricle becomes thickened, or enlarged it causes your heart to work harder.…
There are eleven different systems that works together in order to sustain life. Cardiovascular disease is associated primarily with the cardiovascular system. The cardiovascular system consists of the following structures; heart, blood vessels, and blood. This systems primary function is to circulate blood throughout the body by pumping blood from the heart. Located between the lungs superior to the diaphragm, and surrounded by a protective and supportive covering known as the pericardium is the heart.…
Asian Americans Asian Americans are the fastest growing minority populations in the United States and the number is expected to increase significantly from 18 million in 2010, to 34 million in 2050 (Hastings et al., 2015). Although the number of Asian Americans is constantly growing, research has been limited within the subgroups and only some of the subgroups are being reported. For example, national death registries allow researchers to study population health and look at trends. The problem was that Asian American subgroups were not often studied considering that states do not compile subgroup information on death records. More often than not, subgroups, such as Filipinos, Koreans, Asian Indians, Chinese, Vietnamese, and Japanese are grouped…
My presentation is on Atherosclerosis. Atherosclerosis was named in 1904 by Felix Marchand. Felix and his research team continued research, finding that cholesterol has a big impact on the risk of the disease. Their efforts caused many others to follow in their footsteps and continue research.…
Then from the lungs, the blood goes to the organs of the body bythe arteries. When the blood returns to the heart by the veins, it pumped to the lungs again. Coronary arteries’ function is to supply the heart with the oxygen that is needed during the phsyical activity. The author provides the symptoms, causes, risk factors, and diagnose of coronary heart disease. Also, the article includes the types of treatment that patients need, and preventation ways from coronary heart disease.…
