Pulmonary artery

defect or the more common term is the transposition of the great arteries(TGA). TGA is when the two main arteries, the pulmonary artery and the aorta, are switched in position, or "transposed". As a normal heart, deoxygenated blood returning to the heart from the body is pumped from the right side of the heart through the pulmonary artery to the lungs and to the left side of the heart then back out to the rest of the body with oxygenated blood and the cycle repeats. In TGA, deoxygenated blood returning are not going to the lungs to be oxygenated, but is pumped back out to the body. This happens because…

Pulmonary Atresia is a very serious type of congenital heart condition. There are actually two main characteristics: 1) The pulmonary valve, which allows the blood to flow from the heart to the lungs, is completely blocked. 2) There is a large hole- ventricular septal defect- between the two main pumping chambers in the heart. You see, in a normal heart, the blood passes the pulmonary artery to the lungs to collect oxygen. With people who have pulmonary atresia, the blood can’t pass through…

The doctors gave him medication to slow down the closing of the ductus arteriosus and foramen ovale in the heart so blood could be pumped to both the lungs and the rest of his body by the right ventricle. His first open heart surgery was successful. The surgeon’s performed the Norwood Procedure which basically removed the wall separating the atrium and also attached the pulmonary trunk to the aorta. This procedure was the first of three open heart surgeries that are performed on children with…

Pulmonary Embolism (PE) is a serious and oftentimes life threatening condition that is sadly easily treatable if caught early. The definition of Pulmonary Embolism is a blockage or thrombi in one of the pulmonary arteries of your lungs (Pulmonary Embolism). Most of these thrombi originate in the veins in your lower extremities; though sometimes the thrombi can come from upper extremity veins, renal, pelvic, or right heart chambers, instead. Once in the pulmonary arteries, large thrombi sometimes…

The article, Mass Transport in an Anatomically Realistic Human Right Coronary Artery, written by M.R Kaazempur-Mofrad and C.R. Ethier, analyzes mass transport patterns in a realistic right coronary artery model and looks at what affects mass transport from blood to the wall of the artery. The researchers were looking for any relationships between atherosclerosis, a disease of the arteries characterized by built up plaque on their inner walls, and hemodynamic and mass transport patterns. To…

To Whom It May Concern: October 29, 2013 As Kapolei High School’s biology teacher I am writing to recommend Stephanie Gutierrez Stephanie was my Biology student for one year 2012-2013. Along with being involved in many school extracurricular activities such as weekly piano lessons and volunteering at the Performing Arts Center of Kapolei, Stephanie was a very conscientious student and always put forth her best effort in class and outside of class. In class she was always eager to…

Pericardial Cysts are very rare benign congenital anomalies of the anterior and middle mediastinum with incidence of about 1 in 100,000. 60% are discovered between the ages of 30 to 50 and over 75% of them are right-sided, 22% are left-sided, while the rest are in the posterior or anterior superior mediastinum. Pericardial Cysts are thought to result from the failure of fusion of one of the mesenchymal lacunae that forms the pericardial sac, unfortunately due to the lack of research the true…

TASK 1 HEART The heart is a muscular organ that pumps blood throughout the body (Chiras, 2008). STRUCTURE The heart wall is composed of three layers of tissues: pericardium, myocardium and endocardium (Wilson, Waugh and Ross, 1996). Label structures of the heart for the diagram. Aorta is the major artery that carries oxygenated blood to the body. Pulmonary veins carry oxygenated blood from the lungs into the heart. Left atrium is one of the left upper chambers that takes oxygenated blood from…

circuit. From the heart blood flows through large muscular arteries, then into smaller and smaller arteries, then arterioles and finally to the capillaries. It’s in the capillaries where the diffusion process takes place to exchange molecules of oxygen and nutrients for carbon dioxide of nearby cells, after leaving the capillaries blood is collected into venules the smallest of veins then into veins of increasing size until it reaches the heart [6]. The right side of the heart receives blood…

Though ADO II AS device not been approved by FDA yet, it has been proven to be feasible, effective with a low complication rate when it was used in children as well as in infants. Furthermore, the success of occlusion of PDA with no obstruction of Aorta and/or left pulmonary artery in small infants weighing as less as 1700 grams was demonstrated in both animals and humane studies.…
