- The red network represents the arterial system, which carries oxygen-rich blood away from the heart to the body's tissues.
- The blue network represents the venous system, which returns oxygen-poor blood from the tissues back to the heart.
- The central organ depicted in both figures is the heart, which pumps blood through both systems.
- The kidneys are shown as paired organs receiving blood from both the arterial and venous systems for filtration.
- The lungs are visible in the blue figure, indicating their role in the pulmonary circulation where blood is oxygenated before returning to the heart.
