Haemolymph, is a

fluid, analogous to

the blood in higher

phyla, that

circulates in the

interior of the

arthropod body

remaining in direct

contact with the

animal's tissues.

The open circulatory system is a system in which a fluid in a cavity

called the hemocoel bathes the organs directly with oxygen and

nutrients and there is no distinction between blood and interstitial

fluid; this combined fluid is called hemolymph or haemolymph.
