• The main organ of the circulatory system is the heart, whereas that of respiratory system is lung. Blood flows through closed vessels 2. In organisms with a closed circulatory system, the blood does not fill body cavities. A closed MRI is a machine that takes detailed images of your anatomy in a narrow cylindrical container normally spanning a bore diameter of 60 cm. The closed circulatory system of some mollusks and all vertebrates and higher invertebrates is a much more efficient system. Animals with a closed circulatory system tend to be larger than those with an open circulatory system—consider, for example, an elephant versus a grasshopper. The difference between an open MRI vs a closed MRI is actually quite simple but first let's talk about the closed MRI. This system is much less complex than the closed system.

The closed circulatory system may be of particular interest to you because it is the type of system that humans have. Internal organs are not in direct contact with blood 5. Blood flows at a very high velocity 3. Most vertebrates and some invertebrates, such as this annelid earthworm, have a closed circulatory system. Here blood is pumped through a closed system of arteries, veins, and capillaries. This fluid can be either haemolymph in the open circulatory system or blood in the closed circulatory system. Open Circulatory System. Many vertebrates, such as humans, have a circulatory system known as the cardiovascular system and a secondary system known as the lymphatic system..
