Internal Systems
Inside Barry's body
Circulatory system
Barry's circulatory system is very different from yours! His blood is especially different yours, Barry doesn't actually have blood as he has a fluid called hemolymph. Hemolymph is a fluid similar to blood that flows through the body of Barry and is in direct contact with his tissue.
Barry's heart is a long narrow tube located at the top of his abdomen and is controlled by nerves in the nervous system. His heart pumps hemolymph throughout his body through open passages called sinuses. This means that if Barry's exoskeleton is damaged he will die from loss of hemolymph unless the wound is small enough.
Digestive structure
Barry's mouth is located on the underside of his prosoma under the chelicerae. His mouth is in the shape of a straw that can only suck, so he can only ingest liquids. The chelicerae secrete digestive juices through openings that help break down the prey to suck up his mouth.
His stomach is the entire length of his body, but he has what is called a sucking stomach located in his prosoma. Muscles surround this stomach and contract to suck in the liquefied prey through the mouth and sends it to the intestines. In the intestines the prey is further broken down and is passed into the hemolymph where it is goes through the entire body.
The remains of the prey is formed into a ball and excreted through the anus.

Respiratory System
Barry's respiration is through 4 book lungs. Each lung is composed of 15 thin sheets of folded tissue set up similar to a book in a cavity which are supplied by blood vessels.
Air enters the cavity throughs small slits on the either side of the front of his abdomen. As air enters the lungs, the blood vessels transport the oxygen though his body.
