Who needs a circulatory system? Name 2 phyla without circulatory systems. What are the components of a circulatory system? What are the2 major types of animal circulatory systems? Today we will investigate vertebrate circulatory systems, which are closed systems . The structure and function of the system (in vertebrates usually referred to as the cardiovascular system ) are the result of phylogeny, habitat (whether oxygen is obtained from water or air), and metabolic rate. Generalized Structure of Vertebrate Circulatory Systems The heart is a hollow muscular organ that provides the force and pressure to pump the blood to the cells of the body. The heart consists of chambers (atria and ventricles), valves between the chambers, and associated blood vessels. Blood Vessels transport the blood throughout the body. Arteries (arterial blood vessels) carry blood away from the heart toward the cells. They branch from few large diameter vessels into increasingly more numerous and smaller diameter vessels. Aortae (trunks) leading out of the heart branch into arteries which branch into arteriole s which branch into...
