Give the significance of closed circulatory system.

Explanation

**Step-by-Step Solution:**

1. **Definition of Closed Circulatory System**: The closed circulatory system is a type of circulatory system where blood is contained within a network of blood vessels. This system is primarily found in vertebrates and some invertebrates.

2. **Efficient Transport of Nutrients and Gases**: One of the main significances of a closed circulatory system is that it allows for the efficient transport of nutrients, gases (like oxygen and carbon dioxide), and waste products throughout the body. The presence of vessels ensures that blood can be directed to specific tissues that need it most.

3. **Higher Blood Pressure**: In a closed circulatory system, blood can be pumped at a higher pressure compared to an open circulatory system. This higher pressure allows for faster circulation of blood, which is essential for larger and more active organisms.
