| What is the importance of the "Schistosoma" Fluke? |
|
Definition
It has a typical life cycle of parasitic flukes & other parasites.
1.Flukes mature & reproduce sexually in blood vessels of human intestine. Embryos are released and passed out with feces.

3.After aesexual reproduction, new larvae are released from the snail into the water.
4. Then they infect humans, primary host, by boring through their skin. |
