| right triangular ligament | <anatomy> A triangular fold of peritoneum that passes from the right lobe of the liver to the diaphragm; it is a formation of the coronary ligament, formed as the coronary ligament makes an acute angle upon reaching its most lateral point on the right side as it surrounds the bare area of the liver. Synonym: ligamentum triangulare dextrum. (05 Mar 2000) |

| right ventricle | The muscular chamber of the heart which accepts blood from the right atrium and pumps it through the pulmonary artery into the lungs. (27 Sep 1997) |
| right whale | <zoology> The bowhead, Arctic, or Greenland whale (Balaena mysticetus), from whose mouth the best whalebone is obtained. Any other whale that produces valuable whalebone, as the Atlantic, or Biscay, right whale (Balaena cisarctica), and the Pacific right whale (B. Sieboldii); a bone whale. <zoology> Pygmy right whale, a small New Zealand whale (Neobalaena marginata) which is only about sixteen feet long. It produces short, but very elastic and tough, whalebone. Source: Websters Dictionary (01 Mar 1998) |
| middle lobe of right lung | It is located anteriorly between the horizontal and oblique fissures and includes lateral and medial bronchopulmonary segments. Synonym: lobus medius pulmonis dextri. (05 Mar 2000) |
| posterior branch of right branch of portal vein | <anatomy, vein> Posterior segmental branch of portal vein; branch to posterior segments of right lobe of liver. Synonym: ramus posterior rami dextri venae portae hepatis. (05 Mar 2000) |
| posterior branch of right hepatic duct | Hepatic duct branch draining bile from posterior segments of right lobe of liver. Synonym: ramus posterior ductus hepatici dextri. (05 Mar 2000) |
| posterior branch of right superior pulmonary vein | <anatomy, vein> Drains posterior portion of superior lobe of right lung. Synonym: ramus posterior venae pulmonalis dextrae superioris. (05 Mar 2000) |
| heart bypass, right | Diversion of the flow of blood from the entrance to the right atrium directly to the pulmonary arteries, avoiding the right atrium and right ventricle. This a permanent procedure often performed to bypass a congenitally deformed right atrium or right ventricle. (12 Dec 1998) |
| horizontal fissure of right lung | The deep fissure that separates the upper and middle lobes of the right lung. Synonym: fissura horizontalis pulmonis dextri, horizontal fissure of right lung, minor fissure. (05 Mar 2000) |
| shift to the right | In a differential count of white blood cells in the peripheral blood, the absence of young and immature forms. Synonym: deviation to the right. See: maturation index. (05 Mar 2000) |
| shunt, left to right | A term used to describe the diversion of blood from the higher pressure left side of the heart to the right side (pulmonary circuit). Can be seen in ventricular septal defect, atrial septal defect and patent ductus arteriosus (congenital at birth). (27 Sep 1997) |
| shunt, right to left | <cardiology> A term used to describe the diversion of blood from the right side of the heart to the left. Long standing left to right shunts can lead to increased right sided pressures in the pulmonary circuit (pulmonary hypertension). Eventually the left to right shunt reverses and blood flows from the right to the left. Can be seen in large untreated ventricular septal defect or atrial septal defect. (27 Sep 1997) |
| hypoplasia of right ventricle | Failure of development of the right ventricle resulting in its having little muscle and much connective tissue instead of the reverse. (05 Mar 2000) |
| superior branch of the right and left inferior pulmonary veins | Tributaries of the right and left inferior pulmonary veins which receive oxygenated blood from the superior [S6] bronchopulmonary segments of the inferior lobes of the right and left lungs. Synonym: ramus superior venae pulmonalis dextrae/sinistrae inferioris. (05 Mar 2000) |
| deviation to the right | In a differential count of white blood cells in the peripheral blood, the absence of young and immature forms. Synonym: deviation to the right. See: maturation index. (05 Mar 2000) |
