cephalothorax and abdomen with respect to each other. Rather, their bodies are filled with haemolymph, which is pumped through arteries by a heart into spaces called sinuses surrounding their internal organs.The haemolymph contains hemocyanin, a respiratory protein similar in function to hemoglobin. as well as being released onto the female's silk and possibly some body surfaces as well.

The spider's blood, called hemolymph, circulates oxygen, nutrients and hormones to the different organs in the body.Unlike humans, spiders have an open circulatory system.The spider's simple heart-- a tube surrounded by a muscle, with a one-way valve on each end -- pumps blood into the body cavity, all around the spider's organs.Organs get oxygen because they're soaking in blood.
