Blood Pressure as a Vital Sign

Figure from experiment 10A from Advanced Biology with Vernier

Introduction

Blood pressure is a measure of the changing fluid pressure within the circulatory system. It varies from a peak pressure produced by contraction of the left ventricle, to a low pressure, which is maintained by closure of the aortic valve and elastic recoil of the arterial system. The peak pressure is called systole, and the pressure that is maintained even while the left ventricle is relaxing is called diastole.

Objectives

In this experiment, you will

  • Obtain graphical representation of blood pressure.
  • Compare blood pressure before and after exposure to cold stimulus.
  • Observe an example of sympathetic nervous system activation (“fight or flight” response).

Sensors and Equipment

This experiment features the following Vernier sensors and equipment.

Additional Requirements

You may also need an interface and software for data collection. What do I need for data collection?
