Question

How do taenias get food and create gas exchange?

Answer 1

Tapeworms have hooks and sucking structures on their heads (or scolex) that fixate parasite in the gut wall; such structures often don’t injure the host tissue. The parasite gets food and creates gas exchange throughout the absorption and diffusion across its skin; because it is a platyhelminth it doesn’t having a digestive system or a circulatory system.
