Tricuspid valve

inside the atrium becomes higher than that of the right ventricle, the tricuspid valve opens and allows the blood to flow from high to low pressure. The valve then closes to ensure blood only flows in one direction (Tandy 2017). After oxygenation, the blood enters the left atrium via the pulmonary veins and fills it until the pressure inside the atrium is greater than that of the left ventricle. This then causes the mitral valve to open and then close again after the pressure in the ventricle…

as it travels to the right atrium. Then, from the lungs there are pulmonary veins that brings poor oxygenated blood to left atrium. Also our heart composed of valve called pulmonary valve to prevent our blood to flow back to our right ventricle as if went after it arrives from our pulmonary artery. There is another valve called tricuspid valve that prevents the poor oxygenated blood to flow back into our right atrium. The inferior vena cava is the part of our heart that brings poor oxygenated…

Everyday our bodies need oxygen and different nutrients to function properly but in order to maintain that constancy, our blood has to be constantly moving. And in order for our cells to get transported and get everything they need, the heart needs to be beating. The cardiovascular system makes sure the levels of substances in the blood is constant by transporting these substances as circumstances change. The heart is located in the lower part of the mediastinum between the lungs. Most…

to travel around until one day she came across the right aaaaaatrium she tried her best to go back to her home but realized she had to go through her family's homes first, so that's what she did. The first home she went through is her aunts Anna Tricuspid she had to knock on the door, when she did her aunt Anna opened the door which let her in the home(right ventricle) as soon as she was in there her aunt shut the door behind her. So that meant she had to hang around for a while; Jessie was in…

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.…

to show the interior functioning. The paradigm in patient education is the giant, hands-on, unbreakable heart model, three times the size of a normal, adult heart with three hinged doors which open to reveal the four chambers and their associated valves. On the back, this model also displays an anatomically correct portion of the trachea and esophagus, and the heart can either rotate on its base or be removed for demonstration purposes and comes with a study guide describing the 39 key…

Examination of Ventricular Septal Defects and Arterial Aneurysms According to Maternal Child Nursing Care, 5th Edition, Chapter 47 – Cardiovascular Dysfunction, congenital heart defects occur in about 5 to 8 of every 1000 live births, and 2 to 3 of those affected will be symptomatic within the first year of life (Hockenberry, 2014). When looking at the different pathophysiologies of congenital heart defects, the most common form of defect is the ventricular septal defect or VSD and there are…

Prince George’s Hospital is still making improvements to reach the desired level of quality care provided to patients with conditions such as heart failure, heart attack, surgical infection prevention and pneumonia (Lurie et al., 2009). In spite of the efforts the hospital has made towards quality improvement, there are still cases of patients developing complications. Complications lead to increased readmission, hospital cost, length of stay in the hospital as well as increased mortality. In…

are now in the right side of the heart, literally, the right atrium. The SA node’s action potential fires again and through the tricuspid valve we go. We’re now in the right ventricle. This one is roomy like the left so we have to wait with the AV node until the ventricle fills up some more. Finally! The AV bundle fires and we pump through the pulmonary semilunar valve into the pulmonary trunk and out the pulmonary arteries. We are on our way back to the lungs now. It gets a little small again…

Deoxygenated blood enters the right atrium through the vena cava, is passed through the tricuspid valve, passes through the right ventricle to the pulmonary artery through the pulmonary valve. Blood is then oxygenated in the lungs and passed back to the heart through the pulmonary vein before passing through the left atrium to the left ventricle through the mitral valve. The oxygenated blood is then passed through the aortic valve to the aorta…
