A tapeworm is a parasite that lives in the intestines of humans and animals.Some tapeworms attach themselves to the intestinal wall by means of suckers in their heads.Others float freely in the intestines and absorb food through the walls of their bodies.A tapeworm consists of numerous segments.When a new segment forms,older ones move to the back of the animal.Each segment contains hermaphroditic sexual organs (that is ,organs of male and female).The uterus of each segment fills with eggs,which develop into embryos.Generally,when the egg is ready to hatch,the segment breaks off and is eliminated through the host’s excretory system.These embryos continue their development only if ingested by an intermediate host.One may be infected by tapeworms by eating undercooked beef,pork,or fish.Symptoms include irregular appetite,abdominal discomfort,anemia,weakness,and nervousness.
