Most mollusks have an open circulatory system, except class cephalopoda
Athropods have an open circulatory system. This means their blood is not contained in veins and arteries as it is in all vertebrates.
they donot have a closed irculatory system
Squids have closed circulatory system ya hemer
An amoeba does not have a circulatory system period. They are cells.
squids have a closed circulatory system
yes
Yes.
true
squids have closed closed circulatory systems
no
closed. Open circulatory systems are common in athropods, such as scorpions and insects, but not of mammals. They are when the body lacks blood vessels but has blood throughout the entire cavity of the body. Mammals have closed circulatory systems, as they contain blood vessels.
Earthworms have a closed circulatory system. Blood is pumped throughout its body by ringed blood vessels. An open circulatory system is not contained in vessels. In a closed circulatory system oxygen is carried in blood! hope this helps=)

Most mollusks have a closed circulatory system. However, cephalopods have an open circulatory system.
They have an open-circulatory system. They do not have ventricles to carry through blood. Most mollusks have an open-circulatory system.
Mollusks have an open circulatory system - (mixed interstitial fluid and blood plasma) and yes, they do have a heart. Source: Biology Major

no they dont. They have a closed circulatory system because they are so long.
Not clear on which 3 classes are the "major ones", but Polyplacophorans, Gastropods, and Bivalves have an open circulatory system while Cephalopods have a closed circulatory system.
Amphibians have closed circulatory system Closed
Cephalopods are the only mollusks with a closed circulatory system. They have two gill hearts (also known as branchial hearts) that move blood through the capillaries of the gills. A single systemic heart then pumps the oxygenated blood through the rest of the body. Like most molluscs, cephalopods use hemocyanin, rather than hemoglobin to transport oxygen
closed circulatory system (double circulatory system)
Mollusks which have an open circulatory system, have blood that is pumped into sinuses containing tissue.
Yes it has a closed circulatory system
