the capillaries. Capillaries are microscopic vessels with very thin‚ porous walls. Networks of capillaries are called capillary beds Sites of diffusion They converge into venules at the downstream end‚ and venules converge into veins Portal veins are the only veins that carry blood between capillary beds Heart: Atria - chambers that receive blood Ventricles - pump blood out Single Circulation Bony fishes‚ rays‚ sharks Heart consists of two chambers: one atrium and one ventricle The blood

really does apply. Capillaries join together to form small veins‚ which flow into larger main veins‚ and these deliver deoxygenated blood back to the heart. Veins‚ unlike arteries‚ have thin‚ slack walls‚ because the blood has lost the pressure which forced it out of the heart‚ so the dark‚ reddish-blue blood which flows through the veins on its way to the lungs oozes along very slowly on its way to be reoxygenated. Back at the heart‚ the veins enter a special vessel‚ called the pulmonary arteries‚ into

arteries‚ veins and capillaries. Arteries carry blood away from the heart. Their structure is made up of a thick‚ stretchy muscular wall‚ they have a narrow central tube and they contain no valves. Arteries branch into smaller tubes called arterioles and then into capillaries. Their main function is to carry oxygenated blood. Veins carry blood towards the heart. Its structure is made up of thin walls with little muscle‚ they have a wide central tube and they also contain valves. Veins branch into

The thyroid gland has not only a superior vein and a middle vein which both dumps into the internal jugular vein but also an inferior vein that branches into the subclavian vein.

cardiovascular system‚ which distributes blood‚[1] and the lymphatic system‚[2] which distributes lymph. While humans‚ as well as other vertebrates‚ have a closed cardiovascular system (meaning that the blood never leaves the network of arteries‚ veins and capillaries)‚ some invertebrate groups have an open cardiovascular system. The most primitive animal phyla lack circulatory systems. The lymphatic system‚ on the other hand‚ is an open system. Two types of fluids move through the circulatory system:
