Most mollusks possess an open circulatory system in which body fluid, hemoglyph, is transported largely within sinuses devoid of distinct epithelial walls. The heart is enclosed in a pericardium. The ventricle pumps the hemolymph through a middorsal sinus or blood vessels into the body tissues. Hemolymph drains from the tissues into the gills, whence it returns to the auricles.
Bigfin reef squids have a closed circulatory system, similar to humans.
Gumboot chitons are a small species with eight plates on their side and an open circulatory system. The artery takes the blood to the tissue. It comes back to the heart in a vein.
Apple snails also an open circulatory system which means that blood. The heart of the snail is found on the left side of the body. There is only one ventricle and one auricle. The single ventricle pumps blood through the body through arteries and capillaries. From the capillaries the blood flows into cavties in the tissues of the snail called the hemocoel. From the hemocoel, blood passes into the veins and back. The blood present in snails contains hemocyanin. Hemocyanin is similar to hemoglobin which is found in human blood.
