How many times does a normal human being breathe in a day?

normal respiratory rate accounts for 16-30 cpm for an adult and 24-35 cpm for neonate and infant.\n\nany deviation or greater than those numbers mentioned could mean alteration in your lung function.

Depends on the day. My maximum is at least 9 times (I don't have an exact count...I lost track). I often have days with 4 or more times. My average lately is 2-3 times a day, but some days are more active than others.

that could be roughly true\nit depends on what is your heart rate (which as a matter of fact varies a lot through the day, and at different ages it varies too) and how long you live\nFor example babies have heart rates of 120 to 140 beats per minute while adult range from 60 to 100 \n\nIn the hypothetical case that the heart rate was kept constant through your entire life lets say at 60 (To take the lower end) and that you would live exactly 70 years that would be \n\n60 beats per minute times 60 minutes = 3600 in an hour\n3600 beats in an hour times 24 hours in a day = 86400 beats in a day\n86400 beats in a day times 365 days in a year (If all years had exactly 365 days but that is not true either)= 31536000 beats in a year\n\nand finally 31536000 beats in a year times 70 = 2207520000 (2.2 billion).\n\nSO your teacher is right if we take all these considerations but in life sciences the rule is that nothing is kept always constant

According to the site below:\n\nThe time it takes blood to circulate in the human vascular system varies with age, body size and condition, and whether the person is resting or engaged in vigorous physical and/or emotional activity. Nevertheless, on average the blood fully circulates in the human body some seven to eight times per minute.

We do not "EMIT" carbon dioxide.. we "EXHALE" it... according to my bilogy book.. our lungs get rid of 18 litres of carbon dioxide daily.

Well, today I enjoy just breathing. I have lung disease from too many cigarettes and some days it is a chore to get anything done without being short of breath. Today I am a little better and can see a beautiful world out there just for the enjoyment.

Hmm, if I had to count how many times i sneezed every day it would probably end up being a couple hundred each day, lol! I have very bad allergies and I am constantly sneezing. Usually after the 3rd sneeze, my family members will tell me to shut up(sarcastically) because they know that I will go on forever.

heavy and vigorous exercises increases the demand of oxygen thereby increasing the breathing rate 20-25 timesper minute.Otherwise it is 18-20 times.Certainly not, the effect will be different to different people. an asthematic person may have have even more effect of it. it may be either a rapid increase in breathing rate or problem in inhalation. adults(70-80) have also somewhat effect too.this increases their blood preesure pulse rate and chances of heart failure.

How many are perfectly normal? NONE!

Normally 86,400 to 115,200 times per day.  But it is variable due to various factors like age, sex stature , activity, emotions etc. etc.

You can use a spirometer to do it. Please check out this link I am giving you, it will solve your problem. They have really done it well\nhttp://intranet1.sutcol.ac.uk:888/NEC/MATERIAL/PDFS/HUM_BIO/AS_HUMAN/23U2_T2.PDF\n(We can measure the volume of air moved by the lungs using a. spirometer . The ... air min. −1. with a breathing. rate of 18 breaths min ...)- excerpt from the site.

I usually yawn 3-4 times per day myself, I think you have the record.

hi, \nthis site estimates ~1kg per day, but that is highly dependent on the person's activity level.\n\nsee the question " Q. Should we be concerned with human breathing as a source of CO2?" about 1/3 of the way down.\n\nhttp://cdiac.ornl.gov/pns/faq.html\n\ncheers!
