The circulatory system in which blood is contained in vessels is known as a closed circulatory system. In this system, blood circulates through a network of arteries, veins, and capillaries, allowing for efficient transport of oxygen, nutrients, and waste products. Unlike an open circulatory system, where blood flows freely in body cavities, a closed system maintains distinct blood vessels that enhance control over blood flow and pressure. This type of circulatory system is found in vertebrates, including humans, as well as some invertebrates like annelids.
