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.
The average maximum heart rate is calculated to be 200 for a 20 year-old and then drop 1 beat per minute for every year over 20 until at age 70, where the average maximum is set at 150 beats per minute. Another way to figure your maximum heart rate is to subtract your age from 220 and use the resulting number.
