Cardiovascular System: Organs and Functions Diagram Biology Diagrams
Learn about the circulatory system, also called cardiovascular system, a vital organ system that delivers essential substances to all cells. Explore the structure and function of the heart, blood vessels, blood, and the two circuits: pulmonary and systemic.

In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).The circulatory system has two divisions, a systemic
