Research vessel

recent hypothesis , leukocyte, such as momocyte or basophile start on to attack the endothelium of the artery lumen in cardiac muscles. The consequent inflamtion leads to development of athermanous plaques in the arterial tunica intimae region of the vessel wall to be found between the endothelium and…

graft, radial artery graft (RA) has the benefit of being arterial with less risk of infection. Comparison The saphenous vein is a long superficial vein in the leg. Because vein have valve like structures that control the flow of blood in venous vessels the graft must be reversed to permit the flow of blood. This procedure only remains patent or open in a small number of people after ten years. Patency is improved when extremely careful surgical practice is used to ensure there is no damage at…

The Cardiovascular System is composed of the heart and the blood vessels. The main function of the cardiovascular system is to pump blood around the body. The cardiovascular System is divided into two parts, the systematic circuit and the pulmonary circuit. The systematic circuit contains oxygenated blood and the pulmonary blood contains deoxygenated blood. In order to prevent oxygenated and deoxygenated blood from mixing there is a structure called an interventricular septum. The septum…

from the systolic pressure. There are two factors that may impact the PP, the stroke volume and the elasticity of the arterial system. Loss of arteries elasticity result in decreased response to the normal stimuli for dilation or constriction of the vessels to meet the tissues needs (Karch, 2013). The PP differences is then related to arterial stiffness and associated to coronary artery disease (CAD).…

The vertebral and the carotid artery nourish a collection of blood vessels called the circle of Willis. The carotid artery supplies blood to most of the cerebral hemispheres. It runs up the lateral sides of the neck, then splits into the anterior cerebral artery and the middle cerebral artery. The anterior cerebral artery supplies blood to the medial surface of the frontal and parietal lobes as well as the corpus callosum. The middle cerebral artery supplies the lateral portions of the…

Describe the structure and function of the cardiovascular system Blood vessels Arteries, veins and capillaries takes blood and nutrition to the muscles and back from the heart. Arteries take the blood that has O2 in it away from the heart under high pressure with a small diameter and it has thick muscular walls, and veins take the blood back to the heart under low pressure it has a medium thickness to it and a large diameter because it has valves to stop the blood flowing backwards.…

In the respiratory system you can found nose which is a pathway for air and this is where the oxygen get into the lung and carbon dioxide into the air .Pharynx also known as throat is an other way which air can also enter into the lungs through the mouth. Air also enters into the larynx also known as voice box. It have two main functions as it is a passageway for air to enter into the lungs and a source of vocalization. The epiglottis is a tissue a flap-like cartilage structure contained in…

Cardiovascular disease is heart, strokes and blood vessel disease it is Australia’s biggest health issue at the moment one person will die from cardiovascular disease every 12 minutes and it affects 1 in 6 Australians or 4.2 million people every year. The key stakeholders for cardiovascular disease are lower socioeconomic groups, Aboriginal and Torres strait islander and those people who live in remote areas. They have a higher rate of Hospitalisation and died from CVD this is because it is…

Without the heart, you wouldn't be able to basically live at all. The heart pumps blood through the body’s cardiovascular system. The blood gives oxygen and nutrients to the organs and tissues in the body and gives carbon dioxide to the lungs. We need the heart to survive and have a working cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from…

Clear! The physics behind the electrical life savers, defibrillators “Defibrillation has become an integral part of the emergency response routine. In fact, the American Heart Association considers defibrillation a basic life support skill for paramedics and rescue workers.” (DIRECT QUOTE) The human heart is arguably the most vital organ of the human body, as its coordinated and controlled two-part pumping is necessary to supply blood to the entire body. This supply rate is regulated by the…
