...open, but promptly picked up its beat again on being massaged. Dr. Glenn cut through the right pulmonary artery (see diagram) at its beginning near the ventricle, carried the free end around to a hole, half an inch across, cut in the side of the superior vena cava, and stitched it in, like a plumber's elbow joint. Then he tied off the vein near its normal entrance to the auricle. In this way, 30% to 40% of Kent's venous blood (the proportion carried by the superior vena cava) bypassed the right heart completely, went directly...
Plastic Lung. To the surgeon the heart is the center of a familiar but complex machine (see diagram). Used blood, from which all the body's tissues have removed nourishing oxygen, returns through the two great veins (superior and inferior vena cava) to the right upper chamber (auricle). It empties from there through the tricuspid valve into the right ventricle. This muscular chamber contracts and pushes the blood through the pulmonary valve and pulmonary artery to the lungs to pick up fresh oxygen. Reddened blood returns to the left auricle, passes through the mitral valve into the left ventricle...
Meanwhile, out in the cold reaches of outer space, a band of interstellar cavemen were put to flight just as they were about to burn alive Vena, the beautiful navigator for Rocky Jones, Space Ranger; a bearded, mad scientist was certain to be thwarted by right-thinking Captain Video who, as the press release puts it, is an unbeatable "combination of Einstein, King Arthur and Marco Polo," and Space Patrol's Commander Buzz Corry was zooming through the cosmos intent on reforming the almost limitless supply of villains with his soul-washing Brain-O-Graph...
...hate to lie flat on their backs-many complain that it makes them feel weak-but nobody knew why. There is good reason for the phenomenon, Dr. William F. Mengert of Southwestern Medical College reported last week. The heavy-laden uterus can press too hard on the big vessel (vena cava) carrying blood back to the heart, and thus cause a dangerous drop in blood pressure, or shock. Dr. Mengert hopes that his discovery will save such patients from needless operations, because the real remedy is so simple: turn the woman on her side...
