Humans have a closed circulatory system, in which blood is pumped by the heart through dedicated vessels, where it stays contained, as opposed to an open circulatory system (usually found in invertebrates) where blood is pumped out of the heart and vessels.

mammals have closed circulatory system and further double circulatory system.
Their circulartion system is very similar to humans (closed circulatory system)
Amphibians have closed circulatory system Closed

Rabbits have a closed circulatory system, meaning that their blood flows through a series of vessels and the heart pumps it continuously around the body. This system allows for efficient transport of oxygen, nutrients, and waste products throughout the rabbit's body.
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:)
