Tricuspid valve

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…

Prosthetic Heart Valves for Pediatric Patients Madeline Setear, Biomedical Engineering, University of Rhode Island BME 181 First Presentation, March 6th, 2017 Abstract— Heart valve failure makes up a significant portion of Cardiovascular diseases. Heart valves fail when they are damaged and deteriorating or when they have congenital deformities. Heart valve replacement methods have improved greatly in the past decade. Currently, Mechanical and Biological Heart valve prosthesis exist but both…

What conditions contribute to turbulent blood flow or heart murmurs. Turbulent blood flow occurs as blood moves through narrowed or leaking valves producing a swooshing sound over the precordium and a high heart rate combine with narrowing, causing the heart to handle a larger amount of blood flow than normal; the basis is increased blood velocity, structural valve malfunction, or atypical chambers. Some pathological causes of heart murmurs are anemia, high blood pressure, overactive thyroid,…

first trimester to become the heart. The heart is made up of four chambers: the right atrium, the left atrium, the right ventricle, and the left ventricle. There are two atrioventricular valves: the tricuspid valve in the right side and the mitral valve in the left side. There are also the pulmonary and aortic valves that originate from the right and the left ventricles. The heart is located in the mediastinum. During embryonic development, oxygenated blood from the placenta flows into the right…

Atrioventricular valves, or AV valves, are located between the atria and ventricles. Between the right atrium and right ventricle, the tricuspid valves exist; and the mitral valve separates the left atrium and left ventricle. Chordae Tendineae, which are attached to the AV valves and anchored to the papillary muscles, allow one-way flow by preventing eversion of the valves. Semilunar valves separate the ventricles from the arterial system. The aortic valve separates the left ventricle…

little blood reaching the lungs also cause many defects. Tricuspid atresia and pulmonary atresia are defects that fall under this category. Tricuspid atresia is categorized due to decreased pulmonary circulation and cyanosis from lack of oxygen. The tricuspid valve, an important component structure of the heart, is blocked and hinders blood from leaving the right atrium to the right ventricle. In the case of pulmonary atresia, the pulmonary valve is incapable of reaching full development. This…

The Anatomy of the Mitral Valve The mitral valve, also called the left bicuspid atrioventricular valve, is located in the left side of the heart between the left atrium and the left ventricle. In relation to the sternum, the mitral valve is positioned posteriorly and is at the height of the 4th costal cartilage of the rib cage (Moore, Dalley and Agur, 2014). The valve is composed of two cusps, the anterior and the posterior cusps, which are held in place by chordae tendinous cords (Snell, R.S.…

Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. • The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446). • From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446). • Within the capillary, the oxygen molecule that is taken by the red…

ventricle (LV) [1-2]. The tunnel bypasses the aortic valve and may lead to aortic insufficiency (AI), cardiomegaly, LV dilatation, and congestive heart failure [1-3]. Surgery remains the best definitive treatment option [2-3]. ALVT is exceedingly rare representing 0.001% of all congenital heart defects [2-3], and…

have enough force to push blood blood through the aortic valve and through your body even though it is about half an inch thick. There are many different types of valves located in the heart. The tricuspid valve manages blood flow between the right atrium and the right ventricle. The pulmonary valve regulates blood flow from the right ventricle into the pulmonary arteries, which take blood to your lungs for oxygen. Next, the mitral valve allows oxygen-rich blood from your lungs to enter the…
