Two-pool model

The two-pool model describes how certain substances, like drugs or nutrients, move between two main areas in the body: a central compartment (like blood plasma) and a peripheral compartment (such as tissues). Substances can transfer back and forth between these areas at different rates, affecting how quickly they act or are cleared from the body. This model helps scientists understand and predict how a substance behaves over time, guiding effective dosing and treatment strategies. Think of it as a system with two connected reservoirs, continuously exchanging contents.
