Heart Rate

Introduction

The circulatory system is responsible for the internal transport of many vital substances in humans, including oxygen, carbon dioxide, and nutrients. The components of the circulatory system include the heart, blood vessels, and blood. Heartbeats result from electrical stimulation of the heart cells by the pacemaker, located in the heart’s inner wall of the right atrium. Although the electrical activity of the pacemaker originates from within the heart, the rhythmic sequence of impulses produced by the pacemaker is influenced by nerves outside the heart.

Objectives

In this Preliminary Activity, you will use a Heart Rate Monitor to determine a subject’s heart rate. After completing the Preliminary Activity, you will first use reference sources to find out more about the heart, the cardiovascular system, and heart rate before you choose to investigate a researchable question dealing with heart rate. Depending on sensor availability and your interest, you might decide to use another sensor, such as a Blood Pressure Sensor, in addition to a Heart Rate Monitor. Some topics to consider in your reference search are:

  • heart
  • heart rate
  • cardiovascular system
  • physical fitness
  • maximum cardiac rate
  • homeostasis
  • sympathetic nervous system
  • parasympathetic nervous system
  • heart-rate recovery time
  • fitness index
  • baroreceptor reflex
  • diving reflex
