Detailed explanation-1: -In open circulatory system, the blood is not confined within blood vessels. The blood bathes the organs and tissues directly.

Detailed explanation-2: -In closed circulatory system The cells and tissues are directly bathed in the blood pumped out by heartArteries and veins are lackingThe capillaries are largest blood vessels and closed at their endsblood circulatews through a series of vessels of varying diameters.

Detailed explanation-3: -Open circulatory system: It is primarily found in invertebrates. Here, the blood flows freely through cavities since there are no vessels to conduct the blood. Closed circulatory system: It is found in vertebrates and a few invertebrates, like earthworms. This system has vessels that conduct blood throughout the body.

Detailed explanation-4: -In an open circulatory system, the blood (i.e. hemolymph) bathes the organs and tissues directly. Examples of animals with an open circulatory system are arthropods and most mollusks. In a closed circulatory system, the blood circulates within blood vessels throughout the body.

Detailed explanation-5: -In open circulatory system, the blood vessels open into spaces and not into capillaries, so that blood comes in direct contact with tissues. Whereas in closed circulatory system, blood flows through capillaries connected by arteries and veins.
