| circulation | <physiology> Movement in a regular or circuitous course, as the movement of the blood through the heart and blood vessels. Origin: L. Circulatio (18 Nov 1997) |
|---|---|
| circulation, foetal | The blood circulation in the foetus (the unborn baby). Before birth, the blood from the heart that is destined (in the pulmonary artery) for the lungs is shunted away from the lungs and returned to the greatest of arteries (the aorta). The shunt is through a short vessel called the ductus arteriosus. When this shunt is open, it is said to be a patent (pronounced pá tent) ductus arteriosus (PDA). The PDA usually closes at or shortly after birth and blood is permitted to course freely to the lungs. (12 Dec 1998) |
| circulation time | The time taken for the blood to pass through a given circuit of the vascular system, e.g., the pulmonary or systemic circulation, from one arm to another, from arm to tongue, or from arm to lung; it is measured by the injection into an arm vein of a substance, such as sodium dehydrocholate, ether, fluorescein, histamine, or a radium salt, which can be detected when it arrives at another point in the vascular system.

| collateral circulation | Compensatory circulation carried on through secondary channels after obstruction of the principal vessel supplying the part. (12 Dec 1998) |
| placental circulation | The circulation of blood through the placenta during intrauterine life, serving the needs of the foetus for aeration, absorption, and excretion; also, maternal circulation through the intervillous space of the placenta. (05 Mar 2000) |
| compensatory circulation | Circulation established in dilated collateral vessels when the main vessel of the part is obstructed. (05 Mar 2000) |
| coronary circulation | The circulation of blood through the coronary vessels of the heart. (12 Dec 1998) |
| portal circulation | Circulation of blood to the liver from the small intestine, the right half of the colon, and the spleen via the portal vein; sometimes specified as the hepatic portal circulation, more generally, any part of the systemic circulation in which blood draining from the capillary bed of one structure flows through a larger vessel(s) to supply the capillary bed of another structure before returning to the heart; e.g., the hypothalamohypophyseal portal system. (05 Mar 2000) |
| portal hypophysial circulation | 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) |
| cross circulation | The circulation in a portion of the body of one individual of blood supplied from another individual. (12 Dec 1998) |
| pulmonary circulation | The circulation of blood through the lungs. (12 Dec 1998) |
| Servetus' circulation | An obsolete eponym for the pulmonary circulation. (05 Mar 2000) |
| hypophysial portal circulation | 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 circulation | 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) |
