What_is_the_posterior_opening_of_the_digestive_tract_in_a_fetal_pig
There are two openings to the digestive tract. The anterior opening of the digestive tract is the mouth or oral cavity, and the posterior opening of the digestive tract is the anus.
The posterior opening is the anus & the anterior opening is the mouth or oral cavity
it's called a digestive tract.
it starts at the mouth, and ends at the anus. just like every other higher order animal
The rear half of the fetal pig. The front half would be anterior.

Yes, a sea anemone has a single opening to the digestive tract. This single opening acts as a mouth for feeding and an anus for excreting waste products.
The Anus
Anus

A gastrovascular cavity is a digestive sac with only a single opening. A complete digestive tract (otherwise known as an Alimentary canal) has two openings (a mouth and anus) between its digestive tubes unlike the gastrovascular cavity in which food is ingested and eliminated through the same opening (example would be hydra)
The beginning of the opening of the second part of the digestive tract
No. The mouth is an opening into the beginning of the digestive tract.
Leeches have a complete digestive tract. Leeches are members of Phylum Annelida. This phylum has the general characteristic of having a complete digestive tract, i.e. food goes in through the mouth, pass through digestive tract of some sort like stomach and/or intestine, waste gets discarded through some sort of rectal opening, i.e. anus. In comparison, an incomplete digestive tract generally means food goes in and waste come out of the same opening, i.e. mouth=anus. Lower level invertebrates have incomplete digestive tract like Phylum Cnidaria and Phylum Platyhelminthes members.
The stomach
