Blood flow goes from the heart, to the lungs, and back to the heart again.
Answer:
The correct answer is-forcing blood from the heart into the major arteries

The gastro vascular system in aurelia helps remove carbon dioxide and waste material from aurelia as there is no specialised excretory system. The waste material is diffused out through general body surface.
Aurelia are dioceous which means sexes are separate. Four gonads of either sex lie radially on the floor of gastric pouches. The gametes when ripened gets shed in the stomach from gonads and comes out of the mouth.
The spermatozoa shed by the mouth in seawater gets carried to the body of female by mouth. The fertilization takes place in gastric pouches.
