Double Circulatory System
Advantages of Double Circulation:
- Complete Separation: Oxygenated and deoxygenated blood never mix
- High Pressure Maintained: Blood reaches body organs at high pressure for efficient delivery
- Efficient Oxygenation: All blood returning to body is fully oxygenated
- Metabolic Support: Can support high metabolic rates needed for active warm-blooded life
