Difference Between Open and Closed Circulatory Systems
The major difference between open and closed circulatory system are:
Feature |
Open Circulatory System |
Closed Circulatory System |
---|---|---|
Blood Vessel System |
Absent or poorly developed vessels |
Well-developed network of arteries, veins, and capillaries |
Blood Flow |
Hemolymph flows freely through body cavities (hemocoel) |
Blood circulates exclusively within closed vessel |
Pressure |
Lower blood pressure due to open system |
Lower blood pressure due to open system |
Efficiency |
Less efficient, slower circulation |
Lower blood pressure due to open system |
Respiratory Pigments |
No respiratory pigments are present |
Respiratory pigments are present in this system |
Gasses Transport |
Gases are not transported through the open circulatory system |
Gases are transported via the closed circulatory system |
Examples |
Insects, crustaceans, mollusks |
Vertebrates, some annelids (earthworms) |
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.
