Description:

Description: English: Oscillatory hemolymph flow in the heart of the grasshopper Schistocerca americana I. Movie depicts the grasshopper's 3rd abdominal segment in lateral view, with dorsal oriented upward and anterior to the right. Field of view is 1.3 × 0.9 mm. The dorsal edge of the abdomen can be seen near the top. The diagonal lines running from upper left to lower right are margins of the x-ray transparent Kapton tube; the spotting in the upper right corner is due to residual material on the tube wall. In this video, the large bubbles in the heart enter the frame from the left, reverse direction, and exit to the left, demonstrating oscillatory flow with no net transport. Also note the slower, steadier movement of much smaller particles near the dorsal abdominal wall. These are the injected Definity microbubbles, which appear to be located within the pericardial sinus that surrounds the heart. Date: 2009. Source: Lee W, Socha J (2009).
