Helminths are parasitic worms.
Parasitic Worms- Large macro-parasites called helminths, or parasitic worms, are typically visible as adults to the unaided eye. Many are soil-transmitted intestinal worms that infect the gastrointestinal system. Schistosomes and other parasitic worms live in blood vessels.
Gastrointestinal system- The alimentary canal, often known as the digestive system, is the body's mechanism for ingesting food and expelling solid waste. The mouth, throat, esophagus, stomach, small intestine, large intestine, and anus are all parts of the gastrointestinal system.
