Open Circulatory System
In an open circulatory system, blood is not confined to vessels but flows freely through cavities in the body. This cavity is called hemocoel. This type of system is found in invertebrates such as insects, mollusks, and arthropods. The heart pumps hemolymph (a mixture of blood and interstitial fluid) into the body cavity, where it bathes organs directly. Nutrients and gases are exchanged directly between the hemolymph and tissues. This system operates under lower pressure compared to a closed circulatory system, making it less efficient for transporting oxygen and nutrients quickly.
Difference Between Open and Closed Circulatory System
The difference between open and closed circulatory systems lies in how the circulatory fluid, whether blood or hemolymph, interacts with the body’s tissues and organs. Open circulatory systems and closed circulatory systems are two types of circulatory systems that differ in the way blood flows through the body and how it is contained within vessels.
In this article, we will cover the difference between open and closed circulatory systems.
