Summary Introduction
Concept introduction: The circulatory system is the organ system that permits blood or body fluids to circulate all over the body for distributing all the essential nutrients and gases all over the body tissues. It varies in different group of animals ranging from an open circulatory system seen in insects composed of hemolymph to a highly systematic closed system in mammalians composed of blood, blood vessels, a definite pumping station and the heart.
