How do tapeworms obtain nutrients without a mouth or digestive system?

Tapeworms obtain nutrients by directly absorbing them through their skin, or tegument, which is lined with microvilli that increase surface area for absorption. They inhabit the intestines of their hosts, where they can efficiently uptake digested food, such as glucose and amino acids, as it passes by. This adaptation allows them to thrive without a mouth or digestive system, relying instead on the host's digestive processes.
