• vessels
  • Additionally Hhex is expressed in regions where definitive vessels are known to form and in a pattern consistent with coalescing endothelial progenitors, such as the dorsal aortae, or the sprouting of new vessels (e.g. intersomitic vessels), suggesting that Hhex may participate in the initial phases of both vasculogenesis and angiogenesis.

  • Other pathologies of the truncus arteriosus include transposition of the great vessels (arteries in this case), and tetralogy of Fallot. (wikipedia.org)
  • The aorta ends by dividing into two major blood vessels, the common iliac arteries and a smaller midline vessel, the median sacral artery. (wikipedia.org)
  • dorsal
  • The tube starts receiving venous drainage in its caudal pole and will pump blood out of the first aortic arch and into the dorsal aorta through its polar head. (wikipedia.org)
  • heart
  • A single great artery leaves the heart and gives rise to the coronary, pulmonary, and systemic arterial circulation. (virtualpediatrichospital.org)
  • Davis Collins, Lona and Jared Collins' son, was born premature with a heart defect, truncus arteriosus. (houmatoday.com)
  • In a normal heart, the aorta carries blood out of the left heart ventricle, and the pulmonary artery carries blood out of the right ventricle. (childrenshospital.org)
  • A significant amount of the groundbreaking cardiac research currently being conducted at Boston Children's aims to refine and advance the open-heart surgery and catheterization procedures that correct congenital heart defects in newborns and young children - including truncus arteriosus. (childrenshospital.org)
  • The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. (wikipedia.org)
  • This may occur as a result of heart problems such as heart failure, lung or airway disease such as COPD or scleroderma, or thromboembolic disease such as pulmonary embolism or emboli seen in sickle cell anaemia. (wikipedia.org)
  • One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. (wikipedia.org)
  • In this system, the aorta starts as the ascending aorta then travels superiorly from the heart and then makes a hairpin turn known as the aortic arch. (wikipedia.org)
  • Together, these two arteries supply the heart. (wikipedia.org)
  • When the aorta receives almost five litres of blood from the heart, it recoils and is responsible for pulsating blood pressure. (wikipedia.org)
  • Small physiological, or "normal", shunts are seen due to the return of bronchial artery blood and coronary blood through the Thebesian veins, which are deoxygenated, to the left side of the heart. (wikipedia.org)
  • Because the left ventricle is responsible for getting blood to the entire body through the aorta, it is usually the biggest and strongest chamber of the heart. (wikipedia.org)
  • After the body uses up the oxygen delivered by the blood flowing through the arteries, then arterioles, then capillaries, the unoxygenated blood returns to the heart by the capillaries, then venules, then veins. (wikipedia.org)
  • coronary artery
  • For many years, the combination of the thienopyridine ticlopidine and aspirin has been known to effectively lower the risk of stent thrombosis and carries a lower risk of bleeding compared with other strategies, such as the use of anticoagulants.Although ticlopidine has been shown to be effective in treating patients with acute coronary syndromes who have received a coronary artery stent, it was subsequently replaced with a newer thienopyridine, clopidogrel. (blogspot.com)
  • The morphological types of TGA, the spatial relationship between the pulmonary artery and the aorta, as well as coronary artery-associated abnormalities were assessed by DSCT. (readbyqxmd.com)
  • The left aortic sinus contains the origin of the left coronary artery and the right aortic sinus likewise gives rise to the right coronary artery. (wikipedia.org)
  • capillaries
  • While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. (wikipedia.org)
  • Arteries branch into small passages called arterioles and then into the capillaries. (wikipedia.org)
