Nematoda is the most common group of stomach parasites, and includes hookworms, roundworms, pinworms, heart worms, and trichinosis. Of these, roundworms are the most common, with more than a billion people infected worldwide.
Worms living in humans are also parasites that can cause serious problems. The most famous are intestinal worms (Taenia worm, roundworms, ...), but other worms (liver fluke, pancreas) walk within us. Parasitic worms are divided into roundworms and flatworms.
