Circulation

The Pink Mucket is in the phylum mollusca so therefore it has an open circulatory system.  The pink mucket uses hemolymph as a transport fluid and has a rudimentary heart to pump this hemolymph throughout its system. 

The pink mucket has a few arteries and veins but mostly the transport fluid (hemolymph) is not confined to the blood vessels.  This type of circulatory system creates a low pressure system which is favors sedentary organisms like the Pink mucket.
