Table 1. Processes in different biophysical domains.

Biophysical domain	Biophysical process
fluid kinetics	blood flow, respiratory gas flow
solid kinetics	musculoskeletal mechanics, myocardial contraction
chemical kinetics	cell metabolism, gene expression, cell signaling
electrochemistry	transmembrane ion flow, nerve action potential
diffusion kinetics	alveolar gas exchange, cellular calcium dynamics
heat kinetics	metabolic heat production, body surface cooling

Biophysical processes occur in different biophysical domains and over time spans and spatial scales.
