    Area of Science:

    • Physiology
    • Biophysics
    • Mathematical Modeling

    Background:

    • Vessel network topography influences red blood cell hematocrit, spacing, and flow patterns.
    • Previous work has established mathematical representations for vessel networks.

    Purpose of the Study:

    • To extend the mathematical representation of vessel networks.
    • To apply this vector-based representation to specific biological systems.

    Main Methods:

    • Representing a vessel segment as a vector quantity.
    • Applying this vector representation to the central artery of the gyrus in the human brain.
    • Analyzing the flow mechanism of arteriolar arcades in the bat wing.

    Main Results:

    • The vector representation provides a framework for analyzing complex vessel networks.
    • Insights into the flow dynamics within the human brain's central artery were gained.
    • The flow mechanism in bat wing arteriolar arcades was elucidated.

    Conclusions:

    • Mathematical modeling of vessel networks using vector quantities is a viable approach.
    • This methodology aids in understanding blood flow regulation in different vascular beds.
    • Further research can build upon this vector-based approach for more complex vascular analyses.
