Aorta

Description of Disease Transposition of the great arteries is a life threatening congenital heart defect. In transposition of the great arteries, the two main arteries, the aorta and the pulmonary artery, are reversed. These arteries are responsible for carrying blood away from the heart through the left or right ventricle depending on whether the blood has been oxygenized or not. In a normal heart, there is a constant blood flow pattern in which blood is cycled from the body to the heart, the…

is dissimilar from the other valves because while this valve has two flaps, the others have three. Lastly, the aortic valve is positioned at the departure of the left ventricle of the heart where the aorta instigates. The aortic valve lets the blood from the left ventricle to be evicted into the aorta. Without the help of these four valves, the blood would not properly flow through the heart and into the body.…

Ever since I was a little girl, I always dreamed of helping others, and one of the jobs that would allow me to do this would be being a pediatric cardiovascular surgeon. Along with it being my dream job since I was eight, people who can fill this jobs role will be in high demand by the time I graduate if America stays on it’s fast food heavy diet. Caught in the growing concern in the medical center over this decline of the American diet, I learned of all the bad effects fats in our…

*Unoxygenated blood is driven forward via ventral aorta, passes through a series of branchial arteries in the gills or lungs (as the case may be), where gas exchange takes place. The oxygenated blood flows to the body, most of it returning to its origin via a dorsal aorta. *Red…

body before returning to the heart deoxygenated. The flying fishes have six aortic arches that are responsible for bringing blood to and from the gills. In tetrapods, arches I, II, and V, are lost. Arch III becomes the carotid, arch IV, becomes the aorta, and arch VI becomes the pulmonary trunk. In mammals, such as the jerboa, the left side of the aortic arch is retained. The jerboa has a four chamber heart that runs on a double circuit system. The oxygenated blood comes into the right atrium of…

bounding against the vessels that have delivered oxygen and nutrients to his vital organs for 19 short years. My hands reach for the tubes that the surgeon will use to canalize the aorta. Foresight is important in surgery, so I am prepared for the next step with him. The surgeon finds the correct landmarks to clamp the aorta and the cross clamping time is called out to everyone in the operating room. The surgeon’s words hang in the air as there is one less beating heart amongst us. The…

Humans are terrestrial but they don 't usually live wild in nature ,they make their own environment adapted to their needs, however humans have to live in a place where they can get consistent food supplies such as cow, pigs, chickens and plants. Oxygen and water is essential for human. Humans control their own competitors, predators, parasites, and diseases,humans require large and continual subsidies of energy, food, and other resources. These are needed in order to maintain the colonization…

Introduction: In the field of Forensics Science when dealing with the death of an individual there are three concepts that must be identified: cause, manner and mechanism of death. It is the job of the forensic investigators to help tell the story of the victims deaths by paying attention to detail and having a keen eye. According to James, Nordby and Bell, “drawing such conclusions depends on the information grained from investigations, descriptions of the death scene, case histories and…

For purposes of revascularization, PVD is considered in terms of inflow (aortoiliac) and outflow (infrainguinal) occlusive disease. Revascularization options for these patients are open surgery which includes endarterectomy, bypass surgery, or extra-anatomic bypass [axillofemoral bypass and percutaneous endovascular repair. Aortoiliac and aortofemoral bypass procedures are associated with 74% to 95% 5-year patency rates, respectively, which are comparable but not superior to percutaneous…
