Cardiovascular System

This module allows you to explore cardiovascular system responses to exercise.

Measurable physiological variables in this module:

  • Heart Rate - heart contractions per minute
  • Stroke Volume - volume of blood pumped by the left ventricle per contraction (ml)
  • Cardiac Output - rate of blood pumped by the left ventricle per minute (ml/min)
  • Heart Contractility - heart contraction force at a given volume (inotropy)
  • Blood Pressure - mean blood pressure in the aorta (mm Hg)
  • Muscle Blood Flow - rate of blood flow through skeletal muscle (ml/min)
  • Brain Blood Flow - rate of blood flow through the brain (ml/min)
  • TPR - total peripheral resistance of the vascular system (mm Hg/(ml min))
