Heart Rate & Homeostasis Lab

Collect heart-rate data from a virtual student before exercise, after three repeated activity sets, and during recovery. Use the pattern in the data to explain how the body responds to change and returns toward a stable condition.

Why does heart rate change?

At rest, cells need a steady supply of oxygen and nutrients. During exercise, working muscles increase their demand, so the circulatory system responds.

About This Simulation

This model generates realistic educational heart-rate patterns rather than medical measurements. Individual values vary between virtual students, so students can repeat the investigation and compare results.
