Conclusion
The circulatory system is a marvel of biological engineering, varying vastly across species to meet different metabolic demands. In humans and other vertebrates, a well-developed, closed, four-chambered system ensures efficient oxygen delivery and waste removal, supporting complex life processes. Invertebrates utilize different strategies, from hemolymph to open circulatory pathways, adapting their systems to their environments and lifestyles. Understanding these systems provides insight into how life sustains itself through centuries of evolutionary adaptation.
