Key Points
- To introduce and evaluate the principle of minimum drag as an optimality model governing blood vessel branching angles in the cardiovascular system.
- Formulated a mathematical optimality model based on the principle of minimum drag to predict branching angles.
- Compared model predictions with general anatomical observations and established principles of minimum work and minimum volume.
- The minimum drag principle aligns closely with general anatomical observations of blood vessel branching geometry.
- The proposed principle demonstrates equal consistency with empirical observations and offers greater biological plausibility in specific aspects compared to minimum work and minimum volume models.
