Pulmonary embolism

The Cardiovascular System is one of the most important systems in the body of an organism. It is responsible for carrying the oxygen and nutrients needed for survive through the body. The only organ in this system is the heart, containing four chambers; the left and right atrium and the left and right ventricle, which will be described in further detail later on. Although this system is very important, problems can occur that disrupt the normal routine. One of these we will be focusing on today…

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…

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…

M1 outline the adaptations to cardiovascular, respiratory, musculoskeletal and energy systems, brought about by regular exercise Cardiovascular System The cardiovascular system consists of the blood vessels and the heart. They function is to circulate the blood around the body to all the muscles. The red blood cells carry oxygen to all the muscles through the vein (carries blood to the heart). The veins have thin walls and contain blood under the low pressure. The arteries (carries blood away…

- Inner Layer; An inner endothelial cell layer called tunica intima lines the arteries and veins. The tunica intima, is a single layer of squamous epithelial cells that lines the inner surface of the entire cardiovascular system. In many veins, the tunica intima is equipped with pockets that act as one-way valves. These valves prevent the back flow of blood and allow the veins to act as supplemental pumps that help to keep the blood following in one direction, back toward the heart. The activity…

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 the lungs and pumps it into the left ventricle which carries it to the body (MedicineNet, 2016).…

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…

known as a congenital heart 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.…

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. Left ventricle can be seen encased with thicker muscle in comparison to that…

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.…
