Record your resting heart rate in text box 2.3. Determine you Heart Rate Reserve:• Subtract your resting heart rate from your maximum heart rate. This is knownas the Heart rate Reserve (HRR). Record in text box 3.4. Determine your target heart rate zone:Multiply your HRR (what you recorded in box 3) by 0.70 (70%) and then addyour resting heart rate (from box 2) to that number. This is the minimum heartrate you should achieve during a vigorous exercise routine.Multiply your HRR (what you recorded in box 3) by 0.85 (85%) and then addyour resting heart rate (from box 2) to that number. This is the maximumheart rate you should achieve during a vigorous exercise routine.• Record your target heart rate zone in text box 4.Activate WindoGo to Settings to act When exercising, the American Heart Association recommends the intensity of yourexercise regimen to be determined by your heart rate during exercise. This is knownas a target heart rate zone and it is dependent on your current resting rate, age andfitness level. To calculate your target heart rate zone, complete the following:1. Determine your maximum heart rate:• Subtract your age from 220. (Example, if you are 25 years old 220-25 = 195.195 is your maximum heart rate). Record your maximum heart rate in box 1.2. Determine your resting heart rate:• While sitting at your desk or sitting down, take 3 deep breaths. After takingthe third breath, lightly rest your pointer and middle finger on your neck overyour artery until you can feel your heartbeat. Count the number of times yourheart beats in 15 seconds. Multiply that number by 4. This is your restingheart rate. Record your resting heart rate in text box 2.Activate WindowsGo to Settings to activate

4.4. On the circulatory system, what are the correct statements? PHYSIOLOGY_advanced (OJO) Pacemaker cells of the heart are neurons with a stable resting membrane potential. Pacemaker cells of the sinus node, located at the left atrium, determine the heart beat frequency. Cardiac output is a function of the heart beat frequency and the stroke volume. The Frank-Starling mechanism allows coupling of the venous return with the stroke volume. Within each capillary bed there is a net loss of liquid to the extracellular space; this imbalance depends on the hydrostatic pressure and the colloid osmotic pressure gradients.
