Area of Science:

• Biophysics
• Hematology
• Mathematical Biology

Background:

• Accurate geometric parameters of mammalian red blood cells are essential for biophysical modeling.
• Previous studies may lack comprehensive data on red blood cell dimensions and their implications for physiological processes.

Purpose of the Study:

• To determine the arc length and circumference of mammalian red blood cells across their normal dimensional range.
• To establish the surface area-to-volume ratios for mammalian red blood cells, critical for Fick's Law.
• To present a geometric model of the red blood cell using the Oval of Cassini for Fick's Law application.

Main Methods:

• Calculated arc length and circumference based on established dimensional values for mammalian red blood cells.
• Developed graphs illustrating the relationships between arc length, diameter, and cross-sectional area at fixed thickness.
• Applied a specialized case of Fick's Law using the Oval of Cassini model geometry.

Main Results:

• Provided quantitative data for red blood cell arc length relative to diameter and cross-sectional area.
• Presented graphs indicating the rates of change for key geometric parameters.
• Derived surface area-to-volume ratios for mammalian red blood cells within the normal dimensional range.

Conclusions:

• The study offers essential geometric data for mammalian red blood cells, facilitating accurate biophysical and physiological modeling.
• The derived surface area-to-volume ratios are vital for complete Fick's Law formulations in red blood cell studies.
• The application of the Oval of Cassini model provides a novel geometric approach for understanding red blood cell transport phenomena.
