Pulmonary artery

(ECM): Blood vessels, include arteries that transport blood from the heart to the systemic circulation, and veins that transport blood back again into the heart. A remarkable change in blood vessel structure and function happened, with the emergence of a high-pressure, pulsatile circulatory system in vertebrates. Blood vessels then evolved from simple tubes for channeling blood or other body fluids from a low-pressure heart. According to their sizes and structures, arteries can be subdivided…

Pulmonary Embolism Did you know that just from sitting too long or just any type of prolonged immobility could sometimes be fatal? Life threatening 1/3 of people with undiagnosed and untreated Pulmonary Embolism don’t survive, can lead to Pulmonary Hypertension (PHTN), PHTN is a type of blood pressure that affects the arteries in your lungs and the right side of your heart. When lower extremities are horizontal for long lengths of time, the flow of the venous blood slows and blood can pool in…

the deep vein thrombosis (DVT) and the pulmonary embolism (PE) [1]. The DVT condition commonly occurs in the deep vein of the lower limb or pelvis. Figure 1.1 shows the structure of vein at the lower limb. Furthermore, it can also develop anywhere in the body, such as the veins in the arm, abdomen, or around the brain.A blood clot that forms in the arteries is differed from the blood clots that form in the vein. The reason is that the blood clot in the arteries leads to strokes, transient…

heart which prevents the backflow of blood. They are the bicuspid valve, tricuspid valve, aortic semilunar valve and the pulmonary semilunar valve. The bicuspid valve is located between the left atrium and ventricle. The tricuspid valve is located between the right atrium and ventricle. The aortic semilunar valve is located between the left ventricle and the aorta and the pulmonary semilunar valve is located between the right ventricle and the…

that are associated with coronary circulation are the right coronary artery and the left coronary artery. These two major arteries bifurcate off of the Aorta and encircle the heart ultimately meeting at the coronary sinus. The left main coronary artery which runs across the left side of the heart and passes between the pulmonary trunk and left auricle gives origin to two smaller coronary arteries: the anterior interventricular artery (Also…

This presentation will summarize what Coronary Artery Disease (CAD) is, so the patient and family will have a better understanding of the disease. Coronary Artery Disease is thought to “begin in early childhood and is evident in the teenage years” (http://www.heart.org/). The plaque keeps building up each year and stays with a person for life. As a person ages the risks of coronary artery disease becomes higher with the type of lifestyle a person chooses. “The leading causes of CAD are “high…

stenosis. Due to the obstruction caused by the mitral stenosis left atrial pressure increases, which results in hypertrophy of left atrium. Increased left atrial pressurein turn increases pulmonary venous pressure leading to pulmonary capillary engorgement and eventually pulmonary congestion. The pulmonary artery pressure increases to maintain he forward flow of blood to the left side of the heart.with severe MS, the forward flow is reduced and…

considered an “advanced form of Pulmonary Hypertension.” Pulmonary Hypertension is where the “arteries that carry blood from the heart to the lungs become narrow.” When these arteries become narrow, the pressure within these arteries rise to dangerous levels making the heart have to work harder to pump the blood back to the lungs, this eventually begins to damage the lungs (para. 1). According to the article “Eisenmenger Syndrome in Children”…

(MIs) is admitted to ICU after undergoing coronary artery bypass grafting. After surgery, his preoperative ejection fraction was 45%. He also has controlled hypertension and hypercholesterolaemia. He needs mechanical ventilation and pulmonary artery catheter in place. His blood pressure and urine output have fallen after one hour admission to the ICU. He has no signs of ischaemia, tamponade and acute MI. He is tachycardic, having mild pulmonary oedema, RG is diagnosed to have cardiogenic shock…

using a stethoscope. Typically, these sounds come from the abnormal motion of blood amid cardiac chambers and across valves. As a result, turbulence occurs, bringing about “vibrations in the chambers of the heart or outflow vessels (aorta or pulmonary artery) that are detected as audible, low-frequency sounds,” (Klabunde, 2016). These sounds are different from the regular heart sounds that symbolize the closing of the atrioventricular and semilunar valves amid the cardiac cycle. Murmurs are…
