The Endocrine System of the Hookworm
The Hookworm infects humans by getting into their intestines, and causing infections and diseases. The seminal sac is one of the glands of the Endocrine System of the Hookworm. It's role is to produce semen to carry sperm cells to the female. This is a little different than the reproduction process of the Clam Worm because the Clam Worm does not use the seminal gland to produce semen. It uses the seminal sac as a seminal receptor to store sperm cells.
The seminal sac is also much larger than that of the Clam Worm. This is probably why the Hookworm has more offspring than the Clam Worm. Another difference between this worm and others in its phylum is the distance between the testes or ovaries. Notice that they are a little more spread apart than the testes or ovaries in the Clam Worm.
