Circulation can refer to different systems in biology, but in general terms, the circulatory system in mammals is closed. This means that blood is contained within vessels and circulates through a network of arteries, veins, and capillaries. In contrast, some organisms, like certain invertebrates, have an open circulatory system where blood flows freely through cavities.
