The liver, a functionalized vascular structure.

Area of Science:

• Physiology
• Biophysics
• Vascular Biology

Background:

• The liver is a vital metabolic organ responsible for detoxification.
• Understanding the liver's complex blood vasculature is crucial for comprehending its function.
• Predicting the multi-scale vascular network of the liver presents a significant challenge.

Purpose of the Study:

• To predict the hepatic multi-scale vascular network using the constructal law of design evolution.
• To unveil the structure of the liver's blood flow architecture.
• To predict the geometrical features and permeability of liver vascular systems.

Main Methods:

• Application of the constructal law of design evolution.
• Analysis of superimposed tree-shaped networks and porous systems.
• Comparison of theoretical predictions with anatomical data.

Main Results:

• The study successfully predicts the dendritic structure of the hepatic artery, portal vein, and hepatic vein.
• The principle of equipartition of imperfections explains the geometrical features of the vascular architecture.
• The shape and permeability of liver lobules were also predicted.

Conclusions:

• The constructal law provides a powerful framework for understanding liver vascular design.
• The liver's vascular architecture is a result of evolutionary design principles.
• The findings align well with existing anatomical data, validating the theoretical approach.
