An olfactory receptor neuron (ORN), also called an olfactory sensory neuron (OSN), is a transduction cell within the olfactory system.
The average heart rate for a teenager is around 80-110 beats a minute. <br /><br /><br /><br /> I hope I helped. Well it didn't because you are wrong. If you are a couch potato and never work out maybe 80-110 or if you just got done running. The average heart beat per minute is 60-80 beats per minute. <br /><br /><br /><br /> Well lets see I just got started learning about this in health and my health teacher said that the average heart rate for a teenager when at rest is about 72 beats per minute.
A normal resting heart rate is usually 60-100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults. The maximum heart rate is, on average, the highest your pulse can get. To calculate your predicted maximum heart rate, use this formula: 220 - Your Age = Predicted Maximum Heart Rate. For example, a 40-year-old's predicted maximum heart rate is about 180 beats per minute. Your actual maximum heart rate can be determined by a graded exercise test.
