Nematoda - Roundworms
  
Parasitic roundworms (class: Nematoda, commonly called "nematodes") have small teeth for biting and oral suckers
to hold on to tissue. Some roundworms use enzymes to break down cells which become easier to ingest. Smallest
roundworms are a few millimeters long while some can grow up to 30 centimeters. Their digestive system and
metabolism produce chemicals, which they excrete inside humans causing further infection. For example, ammonia gets
into our bloodstream causing damage to human cells. Roundworms have sensory systems and most have the sense of
touch. They are dioecious and thus reproduce sexually.
