Is your circulatory system open or closed?

A humans circulatory system is closed. Large creatures tend to have a closed system, while smaller creatures like insects and crustaceans have open circulatory systems. Closed is when there are vessels and the blood stays there. Open is when blood floats around the body. Hope it helps:)


Is the bivalves circulatory system open or closed?

Bivalves have an open circulatory system, where blood flows freely within the body cavity instead of through a closed network of vessels. Oxygen and nutrients are distributed to the tissues as the blood bathes them directly.


Compare the circulatory system of each of the three major classes of mollusks?

In cephalopods like octopuses, the circulatory system is closed, with blood contained in vessels. Bivalves like clams have an open circulatory system where blood is pumped into a hemocoel. Gastropods, such as snails, have a mix of closed and open circulatory systems, with a heart that pumps blood through vessels but also into spaces around organs.


Do arthropods have a open circulatory system?

Yes, most arthropods have an open circulatory system, which means that their blood, called hemolymph, directly bathes their tissues. This system is less efficient at transporting oxygen compared to closed circulatory systems found in vertebrates.


In what circulatory system does the blood surround the organs?

In an open circulatory system, the blood does not flow in closed vessels and surrounds the organs directly within the body cavity. This type of circulatory system is found in invertebrates like insects and mollusks.
