Vascular networks

Definition

Vascular networks refer to the intricate systems of tubes and channels that facilitate the transport of fluids, nutrients, and signals within biological organisms. These networks are crucial for maintaining homeostasis, as they allow for efficient distribution of resources and waste removal. In materials science, understanding vascular networks can inspire the development of self-assembling and self-healing materials that mimic these biological systems to enhance their functionality and longevity.
