Which animals have open circulatory system?
Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood. The resulting blood flow is sluggish.
Is the human circulatory system open or closed?

The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
How long is the circulatory system?
