Right ventricle

Heart: Heart has 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood comes back to the right side of the heart with the venous circulation, pumped into the right ventricle and then to the lungs, there, carbon dioxide is released and exchanged with oxygen. The oxygenated blood then travels back to the left side of the heart into the left atria, heading to left ventricle, aorta, and finally arterial circulation. Blood travels from right side to left side via the lungs only. The pressure created

serous membrane called the pericardium, which lubricated the heart and prevent friction. The wall of the heart is made of three layers: epicardium, myocardium, and endocardium. The four chambers of the heart are: the right atrium, left atrium, right ventricle, and left ventricle. The right side of the heart provides pulmonary circulation to the neighboring lungs whereas the left side of the heart pumps blood out to the extremities of the body in the systemic circulatory loop. A system of one way valves

and right ventricular hypertrophy. As a result, blood flow is significantly changed where the blood is not fully oxygenated in the lungs and the tissues in the body receive poor oxygenated blood. This causes severe complications and problems to the patients. History In 1671, Niels Stenson who was a Danish scientist found out tetralogy of fallot. After more than a

shows the boot-shaped characteristic. The aortic arch is on the right side. The boot-shaped is developed due to the upturning of the cardiac apex because the right ventricle hypertrophy and the concavity of the main pulmonary artery. There are four components of a TET heart defect. Pulmonary artery stenosis is a narrowing that happens in the pulmonary artery. This can occur in the main pulmonary artery and in the left or right pulmonary artery branches. This can make it hard for the blood to

Introduction Aspiration is the breathing in (inhalation) of a liquid or object into the lungs. Things that can be inhaled into the lungs include: Food Any type of liquid, such as drinks or saliva Stomach contents, such as vomit or stomach acid Aspiration can be dangerous in children. It can cause problems that are both short-term and long-term. Aspiration is most common in children younger than 4. You can take steps to reduce the risk of aspiration. How do I know if my child is aspirating? Signs

rate of 75 times per minute, it depolarizes faster than the other pacemaker cells of the heart preceding them with their impulses. Located in the superior right atrium, these spontaneously depolarizing myocytes trigger a depolarization wave, via gap junctions, to the left atrium and the atrioventricular (AV) node, lying in the inferior right atrium. Gap junctions, in the intercalated discs, allow the rapid transmission of ions to adjoining myocytes. Furthermore, the electrical signal can conduct

mean having a death sentence. With an occurrence rate of 3 in every 10,000, it is the most common cause of cyanotic cardiac disease. [Wynbrandt, 366] There are four defects that commonly occur together; ventricular septal defect, hypertrophied right ventricle, malposition of the aorta, and pulmonary stenosis. For one to be diagnosed as a Tetralogy of Fallot baby, the patient must present with at least two of the four defects. Any one of these defects can cause serious catastrophe to the cardiac system

Abstract Uhl’s anomaly, an extremely rare form of heart disease. In 1952, founded by Dr. Uhl after conducting an autopsy on a seven month old infant. He had founded that there was little to no myocardium in the parietal wall of the right ventricle. Most often resulting in the death of the patient. Even with the turn of the century and advances in medical science, less than 100 cases has been found since his first discovery. Even in cases that are found, it is usually misdiagnosed for other heart

tricuspid is found in the right side of the heart. It rests between the atrium and the ventricle. The function of this valve is to make sure that blood flows in the correct direction, forward, from the atrium to the ventricle. This is important to make sure that blood doesn't move backwards through the heart. When blood flows backwards through the heart it is referred to as regression or tricuspid regurgitation. Pulmonary Valve The pulmonary valve is found to the right side of the heart. It is located

Dextrocardia is generally a condition where the heart is in the right thoracic region versus the left. The condition can result in normal heart being a little further to the right in the chest than normal, as well as a deformed heart in the right region of the chest and an anatomically mirrored heart in the right thoracic region instead of the left. All dextrocardia is congenital and less 1% of the population has this condition. Most dextrocardia patients have recurring health issues throughout
