English: Typical view of hemolymph flow in the heart of the grasshopper Schistocerca americana II. Movie depicts the grasshopper's abdomen in lateral view, with dorsal oriented upward and anterior to the right. Field of view is 1.3 × 0.9 mm, mostly of the 5th abdominal segment, although the start of the 4th can also be seen on the right side of the image. The dorsal edge of the abdomen can be seen near the top, and the abdominal segment boundary appears on the right. The diagonal lines running from lower left to upper right are margins of the x-ray transparent Kapton tube, whose outer boundary can be seen at the top. This video shows net transport of hemolymph in the heart toward the right (anterograde flow), but intermittent backflow to the left can be seen as well. Note that unlike in Additional file 2, the main tracheal trunks are not compressed along with the pulsatile movements. |
