Interstitial space

Interstitial space refers to the gaps or areas between structures in a material or biological system. In human biology, for example, it describes the fluid-filled spaces between cells and tissues, which are crucial for nutrient exchange and waste removal. In materials science, it can refer to the spaces between atoms or molecules in a solid. These interstitial areas are important for various processes, such as diffusion, absorption, and structural integrity. Understanding interstitial spaces helps in fields like medicine, biology, and engineering by enabling insights into how systems function and interact at a microscopic level.
