Restless Pump, The

Synopsis: Looks at how the heart responds to the demands from the tissues in various physiological situations. During exercise changes in blood flow can be achieved not only by an increase in heart rate, but by a greater output from the heart at each beat. Dramatic changes in blood flow can also occur in the absence of physical exercise, during high-speed flight, for example. Emotional stress can increase both heart rate and blood pressure, and methods for continuously monitoring these variables are demonstrated.

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
