The Key Difference Between Open And Closed Circulatory Systems is that in the open circulatory system, blood and interstitial fluid are mixed together, while in the closed circulatory system, blood and other liquids never mix with each other.
For normal body functions, and to distribute nutrients and other materials throughout the body, most animals require a circulatory system. This could be an open or closed circulatory system. The most basic organizations have a rudimentary circulation system that is beyond the scope of this article. Complex organisms, such as animals and humans, have a closed or open circulatory system that easily pumps blood throughout the body and removes waste from the body.
Compared to the closed circulatory system, the open circulatory system is less complex. Here, the heart pumps blood to open cavities from where blood vessels take it to all parts of the body by bathing all the organs that get in its way. There are no arteries that increase blood pressure and, therefore, these animals have more blood at low pressure.
In addition, organisms that have an open circulatory system have blood mixed with interstitial fluid. Therefore, we call this blood hemolymph, and this blood is not pure as in organisms that have a closed circulatory system.
The closed circulatory system is one of the advanced circulatory systems possessed by vertebrates and a few invertebrates. In a closed system, blood remains within a network of vessels. Therefore, organs do not bathe in the blood, unlike organisms that have an open circulatory system. The closed circulatory system consists of a heart and blood vessels, such as veins, capillaries, and arteries. Therefore, blood never mixes with other fluids. It remains as pure blood. In addition, the heart pumps blood with pressure to supply all parts of the body. Difference Between Open And Closed Circulatory Systems
Both the open circulatory system and the closed circulatory system transport oxygen and nutrients to the organs and eliminate waste. Difference Between Open And Closed Circulatory Systems
