Artery

coronary arteries (Smeltzer, 2011). Upon arriving at 0720 the nurse manager greeted me and the other student, and gave us a quick tour of the control area and examination room. We were informed about the safety precautions used to protect ourselves from imaging equipment and the patient 's from infection and were instructed to wear a lead apron, surgical…

diseases can be obtained from sodium. High Blood Pressure is the first objective we will discuss. High Blood Pressure is an indicator to how much pressure the blood puts on the walls of the arteries. Blood Pressure is determined by blood volume and this tells how much blood is being circulated in the arteries. Anyone who has high blood pressure must watch how much sodium intake they consume. Also, high blood pressure can cause serious health problems. I am also going to talk about the heart…

Introduction. Ischemic heart disease remains a leading cause of morbidity and mortality worldwide 1. Intermediate coronary artery lesions are responsible for about 80% of acute coronary syndromes2. Accurate assessment of the severity of intermediate coronary stenosis represents an everyday challenge for interventional cardiologists. Fractional flow reserve (FFR), which is simply derived by the ratio between distal (Pd) and proximal (Pa) pressures under conditions of maximal hyperemia, represents…

which fibrinous plaques, called atheromas, develop within the walls of the arteries, impairing the flow of blood. High levels of low-density lipoprotein (LDL), a component of cholesterol, are a major contributor to the formation of atheromas. A myocardial infarction occurs when a plaque completely occludes a coronary artery, or when an emboli travels to the coronary artery. (VanMeter & Hubert, 2014). When a coronary artery becomes occluded, oxygenated blood cannot reach the surrounding cardiac…

This buildup restricts blood flow and can block it altogether. Your heart must work harder to push blood through narrowed arteries which increases your blood pressure. This artery narrowing is often the result of eating fatty foods and those high in cholesterol. Diet isn 't the only life choice that impacts heart health. Other behaviors that put you at risk for heart disease include smoking tobacco…

factors. The heart is responsible for pumping blood throughout the body. The arteries take the blood away from the heart and the veins bring it back to it, completing the circuit. This process is what brings oxygen, nutrients, and protection to the body 's cells. It is also the process that takes waste materials from the cells to be removed from the body. If the cardiovascular (cardio – heart, vascular – veins and arteries) system does not work properly, the body cannot function. The main…

system is to transport materials around the body with blood serving as its transport medium. Blood is contained and transported in hollow tubes known as blood vessels. The body has three main types: Arteries, capillaries and Veins. All arteries (with the exception of pulmonary and umbilical arteries) transport Oxygenated blood away from the heart to the rest of the body. They branch off into smaller structures named arterioles which lead to the Capillaries. In the capillaries the blood exchanges…

minute. Mr. Smith is a social drinker who consumes a few drinks on the weekends. He also smokes cigarettes up to two packs a week. Mr. Smith’s paternal grandfather died of a stroke at the age of 55 and both of his parents have a history of coronary artery disease. Mr. Smith refuses to take any blood pressure medication prescribed by his doctor because he believes it will interfere with his sex life. Physical Examination: Upon a current assessment, Mr. Smith is 5 feet and 8 inches tall weighing…

Result of a Cerebrovascular Accident (CVA) of the middle cerebral artery which supplies Brodmann areas 312 and 4 in the left cerebral hemisphere A cerebrovascular accident is also known as a stroke. It is when the blood which flows to the brain is cut off, by a blocked or ruptured artery that goes to the brain, causing the brain not to receive enough oxygen and cells of the brain then die11. ?????? result of CVA on middle cerebral artery 3.2.2 Difference between a haemorrhagic and an ischaemic…

system should begin to function abnormally, it can throw off the body's entire homeostasis, or steady state. The cardiovascular systems distributes oxygen rich blood from the lungs to all of the body's organs and tissues by its heart pump and many arteries and veins. Cells throughout absorb what oxygen and nutrients are needed and then dispose of any carbon dioxide and waste which then flow back to the heart's right chambers and on to the lungs to be exchanged for more oxygen. As you inhale,…
