During the life cycle of a beef tapeworm, a human becomes the primary host.
Cow: Intermediate host to the larval stages of beef tapeworm (Taenia saginata)
The life cycle of a tapeworm typically involves eggs or larvae being ingested by an intermediate host, such as a flea or a rodent. The larvae then develop into a cysticercoid stage before being ingested by the definitive host, usually a human or animal. Once inside the definitive host, the tapeworm matures into an adult and releases eggs through its segments, which are then passed out through the host's feces to start the cycle anew.
The head of a tapeworm. Point of attachement to the host organism.
The tapeworm feeds off the host organism and hurts this body. This means the tapeworm benefits, but the host organism is hurt from the rlationship.
A scolex is the "mouth" of a tapeworm. It is lined with suckers and hooks which help attach the tapeworm to its host.
The head of a tapeworm is called a scolex. The tapeworm attaches itself to the intestine of the host with hooks and suckers that are on the scolex.
parasite/host
Tapeworms can live in a host for 5-10 years.
To attach itself to the intestinal wall of its host.
Tapeworms can reproduce both sexually and asexually. Mature proglottids (segments that make up the body of a tapeworm) contain both male and female reproductive organs. Sperm from a tapeworm will fertilize the egg--either from the same tapeworm or a different one. The proglottid containing the fertilized egg will break off from the body and burst to release the zygote. The zygote is then released through the feces of the host. Zygotes are then consumed by a new host--their primary host--, grow, burrow, form a cyst, and begin the process again.
A parasitic one. The host is harmed, the invader benefits.
An autoinfection is the infection of a primary host with a parasite in such a way that the complete life cycle of the parasite happens in a single organism.
