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.
So, using the example above, here's how to calculate the target heart rate zone for a 34-year-old who has a Maximum Heart Rate of 186 and a Resting Heart Rate of 74: For a 50% Target Heart Rate: [(186 â 74) Ã 0.50] + 74 = 130 bpm. For a 85% Target Heart Rate: [(186 â 74) Ã 0.85] + 74 = 169 bpm.
