WebIt is believed that book-lungs have evolved from the book-gills that are found in the aquatic horse-shoe crabs (e.g., Limulus). Structure: Each book-lung is a compressed sac-like structure and cavity of the book-lung is lined by thin cuticle which is formed of nearly 140 folded delicate leaves or lamellae (Fig. 18.110) with chitinous lining. WebBook lungs are found in hardened pockets generally located on the underside of the abdomen. Diffusion of gases occurs between the hemolymph circulating within thin leaf …

WebThe respiratory system, located in the abdomen, consists of book lungs and tracheae. In spiders the book lungs are paired respiratory organs composed of 10 to 80 hollow leaves that extend into a blood sinus separated by small hardened columns. The lungs open into chambers (atria), which open to the outside through one or several slits ... WebBook lungs are within small openings in the abdomen of the arachnid. The book lungs themselves consist of a series of haemolymph filled plate-like structures. Between the plates there is an air space and this allows air to circulate around the plates. Gaseous exchange then occurs through the surface of the plates.
