What is pseudocoelom Where does it occur?
The pseudocoelom is a fluid-filled body cavity lying inside the external body wall of the nematode that bathes the internal organs, including the alimentary system and the reproductive system (PeriFIG 1).
Which one develops into pseudocoelom?
blastocoel
Option A: A pseudocoelom is a fluid-filled space between the body wall and the digestive tract found in roundworms. Pseudocoelom develops from the embryo’s blastocoel rather than a secondary cavity within the embryonic mesoderm (which leads to a real body cavity or coelom). So, option A is correct.
