 | | Yet, our results show that only 19.6% of internal hydrocarbons are in the hemolymph, and thus suggest that hydrocarbons may play important physiological roles in various internal tissues, in addition to their functions in water balance and as semiochemicals on the cuticular surface. | | | There is a tacit assumption that internal hydrocarbons largely represent hemolymph hydrocarbons. | | | 3.4% of the internal Z9-C23:1, suggesting an association of hydrocarbons with either fat body or hemolymph, or both. |

| | Circulatory System |
| | Hemolymph bathes the organs and muscles of the head as it emerges from the aorta, and then haphazardly percolates back over the alimentary canal and through the body until it reaches the abdomen and re-enters the heart. | | | During each diastolic phase (relaxation), the ostia open to allow inflow of hemolymph from the body cavity. | | | To facilitate circulation of hemolymph, the body cavity is divided into three compartments (called blood sinuses) by two thin sheets of muscle and/or membrane known as the dorsal and ventral diaphragms. |
