• The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle of the heart, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart. (wikipedia.org)
  • The pulmonary vein returns oxygenated blood to the left atrium of the heart. (wikipedia.org)
  • The oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. (wikipedia.org)
  • Ibn al-Nafis described pulmonary circulation as: "the blood from the right chamber of the heart must arrive at the left chamber but there is no direct pathway between them. (wikipedia.org)
  • The blood from the right chamber must flow through the vena arteriosa (pulmonary artery) to the lungs, spread through its substances, be mingled there with air, pass through the arteria venosa (pulmonary vein) to reach the left chamber of the heart and there form the vital spirit. (wikipedia.org)
  • Blood flows through the heart in one direction, from the atria to the ventricles, and out through the pulmonary artery into the pulmonary circulation, and the aorta into the systemic circulation. (wikipedia.org)
  • The function of the right heart, is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation where carbon dioxide can be exchanged for oxygen in the lungs. (wikipedia.org)
  • In the left heart oxygenated blood is returned to the left atrium via the pulmonary vein. (wikipedia.org)
  • The effect on the baby is to worsen the heart failure that is associated with an isolated VSD and to hasten the onset of pulmonary hypertension. (wikipedia.org)
  • A) Severe, symptomatic obstruction of the superior caval vein, with multiple small collateral channels, in a child who had undergone cardiac transplantation following numerous palliative operations for complex congenital heart disease. (bmj.com)
  • This aids in the implication that HAND1 expression is a factor to patients suffering from congenital heart disease. (wikipedia.org)
  • Mutation of HAND1 has been shown to hinder the effect of GATA4, another vital cardiac transcription factor, and is associated with congenital heart disease. (wikipedia.org)
  • HAND factors function in the formation of the right ventricle, left ventricle, aortic arch arteries, epicardium, and endocardium implicating them as mediators of congenital heart disease. (wikipedia.org)
  • 45% of children with Down syndrome have congenital heart disease. (wikipedia.org)
  • Arising from cells derived from the primary heart field in the cardiac crescent, HAND1 goes from being expressed on both sides of the heart tube to the ventral surface of the caudal heart segment and the aortic sac, then being restricted to the outer curvature of the left ventricle in the looped heart. (wikipedia.org)
  • It is very comfortable to wear, The jewel faces outwards so the hinged ring looks best in 'Forward Facing' piercings like septums. (bodyjewelleryshop.com)
  • The Dor procedure uses a circular suture and a Dacron patch to correct LV aneurysms and exclude scarred parts of the septum and ventricular wall and would prove to be the best option amongst the other methods of ventricular remodeling, i.e. (wikipedia.org)
  • Delightfully ornate, our opal heart captive bead makes an excellent gift for your special someone. (freshtrends.com)
  • Collagen contribution to the measure of cardiac performance summarily represents a continuous torsional force opposed to the fluid mechanics of blood pressure emitted from the heart. (wikipedia.org)
  • The apex of the heart becomes circular, hypertrophy ensues in the viable myocardial tissue, and the valve opening widens. (wikipedia.org)
  • A rubber septum is an engineered membrane that permits transfer of a substance (usually liquid or gas) without contact with air, usually using a syringe with needle. (wikipedia.org)
  • Atrial flutter is characterized by a sudden-onset (usually) regular abnormal heart rhythm on an electrocardiogram (ECG) in which the heart rate is fast. (wikipedia.org)
  • Although this abnormal heart rhythm typically occurs in individuals with cardiovascular disease (e.g. high blood pressure, coronary artery disease, and cardiomyopathy) and diabetes mellitus, it may occur spontaneously in people with otherwise normal hearts. (wikipedia.org)
  • Type V: cell surfaces, hair and placenta The collagenous cardiac skeleton which includes the four heart valve rings, is histologically, elastically and uniquely bound to cardiac muscle. (wikipedia.org)
  • Cardiac muscle tissue has autorhythmicity, the unique ability to initiate a cardiac action potential at a fixed rate - spreading the impulse rapidly from cell to cell to trigger the contraction of the entire heart. (wikipedia.org)
