The correct Answer is:
To answer the question about the advantages of a closed circulatory system over an open circulatory system, we can break it down into the following steps: ### Step-by-Step Solution: 1. **Definition of Circulatory Systems**: - A closed circulatory system is one in which blood is contained within vessels and is circulated by the heart. - An open circulatory system, on the other hand, allows blood to flow freely in open spaces or cavities, mixing with interstitial fluid. 2. **Blood Flow Direction**: - In a closed circulatory system, blood can be directed specifically to tissues that require it, allowing for more efficient delivery of oxygen and nutrients. 3. **Rate of Exchange**: - The closed system allows for rapid movement of blood through vessels, facilitating quicker exchange of gases, nutrients, and waste products between blood and tissues. 4. **Metabolic Activity**: - Organisms with a closed circulatory system tend to have higher metabolic rates. This is because the efficient transport of oxygen and nutrients supports more active lifestyles. 5. **Examples**: - Many animals, including humans, possess a closed circulatory system, which correlates with their higher metabolic demands compared to those with open systems. 6. **Conclusion**: - The advantages of a closed circulatory system include the ability to direct blood flow to specific tissues, rapid exchange of materials, and support for higher metabolic activity. ### Final Answer: The advantages of a closed circulatory system over an open circulatory system include: - The ability to direct blood to specific tissues. - More rapid exchange of gases and nutrients. - Support for higher metabolic activity.
