	NationMaster - Encyclopedia: Circulatory system
		An open circulatory system is an arrangement of internal transport present in some invertebrates like mollusks and arthropods in which circulatory fluid in a cavity called the hemocoel (also spelled haemocoel) bathes the organs directly and there is no distinction between blood and interstitial fluid; this combined fluid is called hemolymph (also spelled haemolymph).
		The circulatory systems of all vertebrates, as well as of annelids (for example, earthworms) and cephalopods (squid and octopus) are closed, meaning that the blood never leaves the system of blood vessels consisting of arteries, capillaries and veins.
		Circulatory System, or cardiovascular system, in humans, the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products.

	Circulatory system - Wikipedia, the free encyclopedia
		The digestive system is very branched, and because the worm is so flat, digested materials can be diffused to all the cells of the flat worm.
		The main components of the circulatory system are the heart, the blood, and the blood vessels.
		In fish, the system has only one circuit, with the blood being pumped through the capillaries of the gills and on to the capillaries of the body tissues.

	circulatory system - Hutchinson encyclopedia article about circulatory system
		System of vessels in an animal's body that transports essential substances (blood or other circulatory fluid) to and from the different parts of the body.
		In birds and mammals, there is a double circulatory system – the lung or pulmonary circuit and the body or systemic circuit.
		The human circulatory system performs a number of functions: it supplies the cells of the body with the food and oxygen they need to survive (see nutrition); it carries carbon dioxide and other waste products away from the cells;; it helps to regulate the temperature of the body; and protects the body from disease.

		The circulatory system of arthropod s and most mollusk s is open, meaning that there are no capillaries and veins: one or more hearts pump the blood (more properly called hemolymph in this case) through the arteries to spaces called sinuses which surround the organs, allowing the tissues to exchange materials with the hemolymph.
		The circulatory systems of all vertebrate s as well as of earthworm s, squid s and octopus es are closed, meaning that the blood never leaves the system of blood vessels consisting of arteries, capillaries and veins.
		This fluid is returned to the bloodstream as lymph, via the lymphatic system, a system of lymph vessels separate from the circulatory system and without a central pump.

		In addition, when foreign substances or organisms invade the body, the circulatory system swiftly conveys disease-fighting elements of the immune system, such as white blood cells and antibodies, to regions under attack.
		Also, in the case of injury or bleeding, the circulatory system sends clotting cells and proteins to the affected site, which quickly stop bleeding and promote healing.
		The systemic circulation carries oxygenated blood from the heart to all the tissues in the body except the lungs and returns deoxygenated blood carrying waste products, such as carbon dioxide, back to the heart.

		The circulatory system is responsible for the transport of water and dissolved materials throughout the body, including oxygen, carbon dioxide, nutrients, and waste.
		The circulatory system transports oxygen from the lungs and nutrients from the digestive tract to every cell in the body, allowing for the continuation of cell metabolism.
		The circulatory system also transports the waste products of cell metabolism to the lungs and kidneys where they can be expelled from the body.

	Circulatory System
		Arthropods, like insects and spiders, have an open circulatory system, in which the blood is pumped forward by the heart, but then flows through the body cavity, directly bathing the internal organs.
		Vertebrates, like humans, have a closed circulatory system in which the blood stays in the circulatory system as it circulates, and chemicals are exchanged by diffusion.
		The two major exceptions, in which arteries are carrying deoxygenated blood are the pulmonary artery which carries deoxygenated blood from the heart to the lungs (to pick up oxygen there) and the umbilical arteries which carry deoxygenated blood away from the baby’s body to the placenta (to pick up oxygen there).
