After release from the oviduct, they are stored in the marsupium, a fluid-filled pouch present in reproducing females. The main organs involved in the respiration process are gills (tadpole), skin and lungs (adult frog). As blood flows through certain organs of the body, the composition of the blood changes because of interactions with those organs. Conglobation has been hypothesized to be either a defense mechanism used to shield the softer inner abdomen and limbs with the more stiff outer shell or an effective method of further preventing desiccation.

(Karasawa, et al., 2012), Many arthropods commonly bear populations of Wolbachia sp., an endosymbiotic bacterium that usually reinforces the host's immune system and is passed down through generations through maternal gametes. Within the oviduct, the sperm are immobilized within an epicuticular envelope bundle. The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. 2 See answers It is both digestive and respiratory organ. They're still a bit "fish out ofwater," though, as they are at risk of drying out on land; they haven't developed the waterproof waxy coating of arachnids or insects.
