    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 HLHS. We were unable to hold our baby for the first few weeks of his life and seeing him, hooked up to all those machines, looking so helpless, broke my heart. I wished with all of my heart that I could take away the pain that he was going through, but I was just as helpless in this situation as he was. During his recovery from the first surgery, my wife and I basically lived in the hospital. We got to know the nurses and doctors extremely well. We don’t know what we would have done without them. As time went on, we got more hopeful as our baby began showing signs of improvement. However, we knew that he still had at least…

    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…

    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…

    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…

    Fetal circulation differs greatly from that of a newborn heart. Although, outwardly appearances may seem similar. By taking an internal look we may be able to distinguish four adaptations that fetal hearts undergo while in utero. First, we must understand that the fetus receives all blood and nutrients from the parental placenta. The fetus receives this blood from the placenta through the umbilical vein. This is the first adaptation that we see in the fetal cardiovascular circulatory system.…

    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.…

    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…
