which organ is used for feeding in the planaria? is it gastrovasular cavity?
is it an area you would expect in a bilateral symmetrical circulatory system?

No, it is not a gastrovascular cavity. That is only in the Cnidar philum. Planaria has a buco-anal orifice that continues with a musculos pharynx and a very ramificated intestine...
