A tapeworm is a parasitic flatworm that belongs to the class Cestoda. It is characterized by its long, ribbon-like body consisting of segments called proglottids. Tapeworms typically inhabit the digestive tracts of vertebrates, including humans, where they can cause health problems. They lack a digestive system of their own and absorb nutrients directly from their host's intestine. Tapeworms have complex life cycles involving intermediate hosts, such as small animals or insects, where they develop and reproduce. In humans, tapeworm infections can occur through the consumption of contaminated food or water, leading to symptoms like abdominal pain, weight loss, and digestive disturbances. Proper hygiene and safe food practices are important for preventing tapeworm infections.
