What is the difference between an open circulatory system and a closed circulatory system?
Expert Solution & Answer
Summary Introduction
To explain: The difference between an open circulatory system and a closed circulatory system.
Introduction:
The circulatory system is the organ system that transfers blood to and from all body parts. The heart is the main organ of circulatory system other than blood vessels. It is classified into two types, namely open and closed circulatory systems.
Explanation of Solution
Differences between open and closed circulatory system:
The closed type of circulatory system is advanced and shows quick distribution. The differences between open and closed type of circulatory systems are as follows:
- Open circulatory system is found in many invertebrates and some animals such as insects, spiders etc. Closed circulatory system is found in all vertebrates.
- In open system, the heart pumps blood through open cavities, whereas in closed system, the heart pumps blood through blood vessels such as arteries and veins.
- In open system, the blood flows at low pressure and requires less energy. In closed system, the blood flows at high pressure and is more efficient.
