Circulatory Systems are bodily systems used to transport nutrients, blood, gases, wastes and other materials of the body to and fro from one part to another part. The open circulatory system is the type of circulatory system in which there are no blood vessels to carry out the function of blood transportation throughout the body of the organism. Introduction to Circulatory System in Earthworm: Earthworms possess a closed circulatory system in which blood always flows in the vessels and never comes in direct contact with tissues. In higher animals, there are two primary types of circulatory systems: open and closed. The Circulatory System. A closed circulatory system, found in all vertebrates and some invertebrates, circulates blood unidirectionally from the heart, around the body, and back to the heart. In this type of system, there is neither a true heart nor capillaries as are found in humans. The open circulatory system is where the hemolymph flows in the organs and tissues directly. An open circulatory system. They are called open circulatory system because blood is not contained in the closed circuit of vessels. Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood . In an open circulatory system, blood vessels transport all fluids into a cavity. Here, a heart pumps the blood fluid into a hemocoel. Open Circulatory System: In this type of circulatory system, the blood pumped by the heart passes through large vessels into open spaces or body cavities called sinuses. An open circulatory system A)is found in flatworms B)typically includes a hemocoel C)has a continuous circuit of vessels with openings in the capillaries D)is characteristic of vertebrates E)is typically found in animals with a two-chambered heart. Figure 21.2. Circulatory systems are present in the simplest organisms like sea sponges. Click again to see term . The open circulatory system is the type of circulatory system in which there are no blood vessels to carry out the function of blood transportation throughout the body of the organism. A closed circulatory system is the type of system where blood circulates in closed vessels. Open circulatory system : primarily found in invertebrates. Instead of a complex and closed system of veins and arteries, organisms with open circulatory systems have a "hemocoel." This is a central body cavity found inside most invertebrate animals where both digestive and circulatory functions are performed. In cockroach, the blood vascular system is of open type, i.e.9 the blood does not flow in the vessels or capillaries, but moves through the internal open spaces and comes in direct contact with the body organs. This system has actually vessels that conduct blood throughout the body. The blood in the body flows through a system of arteries, veins and capillaries. It carries oxygen and essential nutrients to all cells around the body in arteries and carries the waste products and carbon dioxide in veins. Why is the closed circulatory system considered advantageous over the open circulatory system? In organisms with a closed circulatory system, the blood does not fill body cavities. Open circulatory system components? When the animal moves, the blood inside the cavity moves freely around the body in all directions. What are some of the advantages of an open circulatory system?
