|---|---|
| hypertension, portal | Abnormally increased pressure in the portal venous system; frequently seen in cirrhosis of the liver and in other conditions which cause obstruction of the portal vein. (12 Dec 1998) |
| hypophysial portal system | A capillary network that carries hypophyseotropic hormones from the hypothalamus, where they are secreted into blood, to their sites of action in the anterior hypophysis. See: portal circulation, hypophysis, hypothalamus. Synonym: hypophyseoportal system, hypophysial portal circulation, hypophysial portal system, hypophysioportal system, hypothalamohypophysial portal circulation, hypothalamohypophysial portal system. (05 Mar 2000) |
| hypothalamohypophysial portal system | A capillary network that carries hypophyseotropic hormones from the hypothalamus, where they are secreted into blood, to their sites of action in the anterior hypophysis. See: portal circulation, hypophysis, hypothalamus. Synonym: hypophyseoportal system, hypophysial portal circulation, hypophysial portal system, hypophysioportal system, hypothalamohypophysial portal circulation, hypothalamohypophysial portal system. (05 Mar 2000) |
| splanchnic circulation | The circulation of blood through the vessels supplying the abdominal viscera. (12 Dec 1998) |
| splenic portal venography | Introduction of radiopaque material into the spleen to obtain an X-ray visualization of the portal vessel of the portal circulation. Synonym: splenic portal venography. Origin: spleno-+ portography (05 Mar 2000) |
| systemic circulation | The circulation of blood through the arteries, capillaries, and veins of the general system, from the left ventricle to the right atrium. Synonym: greater circulation. (05 Mar 2000) |
| thebesian circulation | The system of smaller veins in the myocardium. (05 Mar 2000) |
| embryonic circulation | The basic plan of the circulation of a young mammalian embryo, at first similar to that in aquatic forms, with an unpartitioned heart and conspicuous aortic arches in the branchial region; as gestation progresses, the arrangement of the major blood vessels gradually approaches that of an adult, but the routing of blood through the heart, characteristic of an adult, cannot be attained until lung breathing begins at birth. (05 Mar 2000) |
| transverse part of left branch of portal vein | <anatomy, vein> The long unbranched portion of the left branch of the portal vein. Synonym: pars transversa rami sinistri venae portae hepatis. (05 Mar 2000) |
| enterohepatic circulation | Recycling through liver by excretion in bile, reabsorption from intestines into portal circulation, passage back into liver, and re-excretion in bile. (12 Dec 1998) |
| extracorporeal circulation | Diversion of blood flow through a circuit located outside the body but continuous with the bodily circulation. (12 Dec 1998) |
| umbilical part of left branch of portal vein | <anatomy, vein> The highly branched part of the left branch of the portal vein; the round and venous ligaments attach to this part. Synonym: pars umbilicalis rami sinistri venae portae hepatis. (05 Mar 2000) |
| uteroplacental circulation | The circulation of blood through the uterus and placenta. (12 Dec 1998) |
| foetal circulation | The blood circulation in the foetus before birth. Before birth, the blood from the heart headed for the lungs in the aptly named pulmonary artery is shunted away from the lungs and returned to the greatest of arteries, the aorta. This arterial shunting occurs through a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent (pronounced pá tent). The ductus arteriosus usually tourniquets itself off at or shortly after birth. After closure of the ductus, blood is permitted from that time on to course freely to the lungs. Sometimes, however, the patent ductus arteriosus (PDA) persists and simply will not close by itself. Surgery is then done to ligate (tie off) the ductus PDA ligation is a closed-heart operation. Historically, it was one of the earliest surgical procedures performed in children with cardiovascular disease. (12 Dec 1998) |
