Question

Compare and contrast systems in frogs and worms?

Answer 1

The worm's reproductive systems are located near the head end of the body, right above the esophagus. Frogs and pigs should be fairly similar although it's been years since I've dissected the frog. I just dissected a worm last week though and the digestive system is different from the pigs or the frogs because it contains a crop and gizzard. These are for breaking down the hard soil and such. For circulatory systems, the worm as 5 pairs of hearts located in the same area as the reproductive systems. Also, the worm reproduces in a very different way from the frog or pig so it has very different structures. The worms are hermaphroditic, meaning they contain male and female structures. So when two worms come together, they both exchange sperm. First, they adjoin, facing opposite ways, with their clitellum (the bandaid looking thing) touching. They exchange sperm and hold it in sperm receptacles. Later, the clitellum forms a ring that the worm edges out of that contains the eggs.
