In a closed circulatory system, the circulatory fluid remains within blood vessels at all points in the circulatory system.
In an open circulatory system, the circulating fluid enters a sinus at least at one point in the circulating system and thus comes in direct contact with the tissues.
In an open circulatory system there is no distinction between circulating fluid and extracellular fluid of the body tissues (hemolymph- cells and such are bathed in a fluid; there are no tubes).
In a closed circulatory system the circulating fluid (blood) is always enclosed within vessels (I'm pretty sure that's just veins, arteries, capillaries, arterioles which are smaller arteries, venules which similar to veins only smaller, and such) that transport blood away from, and back to, a pump (heart).
A closed circulation is what we have, arteries and veins all the way, every drop controlled. An open circulation has the veins fall away at some point or entirely, bathing the organs in blood entirely. Insects have this, for example.
An open circulatory system is a type of blood-circulation system that lacks blood vessels and in which blood washes over the organs. A closed circulatory system is a type of blood-circulation system in which blood is transported through blood vessels rather than washing over the organs.
they are open because blood pumps through them freely and humans are closed
May i know in which related you need an answer, i mean in physics, human system etc. pleas be specific.....
In a closed circulatory system, the blood is contained within blood vessels at all times. In an open circulatory system, the blood is mixed with other bodily fluids.
no
squids have closed closed circulatory systems
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=)
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.
Most mollusks have an open circulatory system, except class cephalopoda
