    Area of Science:

    • Biophysics
    • Hematology
    • Geometric modeling

    Background:

    • Mammalian red blood cells (RBCs) possess specific geometric properties crucial for their function.
    • Accurate calculation of RBC geometric quantities like surface area and volume is essential for understanding cell behavior and disease states.
    • Previous formulas for RBC geometry, such as those by Funaki, may require refinement.

    Purpose of the Study:

    • To accurately calculate the cross-sectional area, volume, and surface area of mammalian red blood cells.
    • To rederive and apply formulas for geometric quantities of red blood cells.
    • To compare newly calculated surface area values with those previously reported by Funaki.

    Main Methods:

    • Utilized the normal range of dimensional values for mammalian red blood cells.
    • Applied formulas for geometric quantities, originally derived by Funaki and rederived by the authors.
    • Performed calculations to three-decimal-place accuracy.

    Main Results:

    • Precise calculations of cross-sectional area, volume, and surface area for mammalian red blood cells were obtained.
    • The rederived formulas were applied to determine these geometric quantities.
    • Significant differences were observed between the newly calculated surface area values and those reported by Funaki.

    Conclusions:

    • The study provides accurate geometric quantities for mammalian red blood cells.
    • The discrepancies in surface area calculations highlight potential limitations in existing models.
    • Further investigation and validation of red blood cell geometric formulas are warranted for improved hematological research.
