The heart in arthropods is often a muscular tube that operates the length of the human body, underneath the back and within the foundation of the head. Rather than blood the circulatory fluid is haemolymph which carries the most often employed respiratory pigment, copper-primarily based haemocyanin given that the oxygen transporter. Haemoglobin is only employed by several arthropods.[158]
