| left superior intercostal vein | <anatomy, vein> The vein formed by the union of the left second, third, and fourth intercostal veins; it passes forward across the arch of the aorta to empty into the left brachiocephalic vein and frequently communicates also with the accessory hemiazygos vein. Synonym: vena intercostalis superior sinistra. (05 Mar 2000) |
|---|---|
| left superior pulmonary vein | The vein returning oxygenated blood from the left superior lobe of the lung to the left atrium. Synonym: vena pulmonalis superior sinistra. (05 Mar 2000) |
| left suprarenal vein | <anatomy, vein> The vein from the hilum of the left suprarenal gland that passes downward to open into the left renal vein; it usually is joined by the left inferior phrenic vein. Synonym: vena suprarenalis sinistra. (05 Mar 2000) |
| left testicular vein | <anatomy, vein> Vein conveying blood from the left testis, originating as the pampiniform plexus and entering the left renal vein. Synonym: vena testicularis sinistra. (05 Mar 2000) |
| left-to-right shunt | A diversion of blood from the left side of the heart to right (as through a septal defect), or from the systemic circulation to the pulmonary (as through a patent ductus arteriosus). (05 Mar 2000) |
| left-to-right shunts | <radiology> Atrial septal defect, ventricular septal defect, patent ductus arteriosus, aorticopulmonary window, endocardial cushion defect, partial anomalous pulmonary venous return (12 Dec 1998) |
| left triangular ligament | <anatomy> A triangular fold of fibrous connective tissue and peritoneum that extends from the left lobe of the liver to the diaphragm. Synonym: ligamentum triangulare sinistrum. (05 Mar 2000) |
| left umbilical vein | <anatomy, vein> The vein that returns the blood from the placenta to the foetus; traversing the umbilical cord, it enters the foetal body at the umbilicus and passes thence into the liver, where it is joined by the portal vein; its blood then flows by way of the ductus venosus and the inferior vena cava to the right atrium. Synonym: vena umbilicalis sinistra. (05 Mar 2000) |
| left ventricle | <anatomy> The muscular chamber of the heart which accepts blood from the left atrium and ejects it into the aorta to the systemic circulation. (27 Sep 1997) |
| ligament of left superior vena cava | The obliterated left common cardinal vein that extends from the left brachiocephalic vein to the oblique vein of the left atrium. (05 Mar 2000) |
| ligament of left vena cava | The obliterated left common cardinal vein; it extends from the left brachiocephalic vein to the oblique vein of the left atrium. Synonym: ligamentum venae cavae sinistrae. (05 Mar 2000) |
| lingula of left lung | An inferomedial projection from the anterior aspect of the upper lobe of the left lung which bounds the cardiac notch inferiorly. Synonym: lingula pulmonis sinistri. (05 Mar 2000) |
| abdominal pressure | Pressure surrounding the bladder; estimated from rectal, gastric, or intraperitoneal pressure. (05 Mar 2000) |
| absolute pressure | Pressure measured with respect to zero pressure. Compare: gauge pressure. (05 Mar 2000) |
| acoustic pressure | In ultrasound, the instantaneous value of the total pressure minus the ambient pressure; unit is pascal (Pa). (05 Mar 2000) |
