how much oxygen does an average man consume in his lifetime?

Let's do the math. 10 breaths per minute at (let's guess on this one) 2 Litres per breath times 60 minutes per hour times 24 hrs per day times 365 days per year times 72 years. My calculator says about 760 million liters. Again, this is approximate as each person is different and of course we are smaller as children. Now, we don't use all of it; only abot 2-3% and we exhale the rest. So that calculates to about 19 million liters.

It depends on how far out of the water you wish to be.  Humans are very close to being bouyant-we are more dense than water, but have lungs full of air, thus a lean man with a large lung capacity is bouyant with a deep breath.  Its isnt the pounds of air that matter, its the pounds of water displaced by the air.  If you hold onto a 10 gallon jug full of air, it displaces 10 gallons worth of water, which is about 80 pds-well more than you need to keep your upper body above water.  For a 200 pd man, he would need an water-displacing container of 25 gallons (this could be a boat or anything else that displaces water for air).

It is carbon dioxide molecules produced devided by oxygen molecules consumed. In humans it is roughly 0.8

Normally between 5-7 liters, depending on the size of the person, or 7-8% of the persons body weight

It depends how fast your heart beats, in an average healthy adult it's approximately 100,000 times a day, roughly 70 times a minute.

I know the average for adults is 6500KJoules but you would need to convert that to calories sorry! Its called something like the "energy of basal metabolism" if its just the basic needed to keep a person alive so if you search for that you can find what it would be for women.

If the average human breathes about 16 times a min then 23040 times

None whatsoever. I know a guy who has 3 stints and is a flight crew. With three stints he has achieved extra blood flow to his male member. It has got a new life. By the way this guy is 53+.

With the average heart rate of 72 beats per minute the heart will pump about 5 litres per ventricle, or about 10 litres total per minute. This is called the cardiac output. In a trained athlete the total cardiac output is about 20 litres. If we multiply the normal, non-athlete output by the average age of 70 years, we see that the cardiac output of the average human heart over a life time would be about 1 million litres, or about 250,000 gallons(US)!

Most sources state the volume of blood in an average human adult, who is between 150 to 160 pounds, as between 4.7 and 5 liters, although the more recent sources state the volume of blood in an average adult as 4.7 liters. Sources state that an 80-pound child had about half that amount, and an 8-pound infant has about 8.5 ounces. People who live at high altitudes, where the air contains less oxygen, may have up to 1.9 liters more blood than people who live in low altitude regions

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!

About a million years:\n\nSun puts out about 3.8*10^26 W\nWe use about 1.2*10^13 W\njust divide and convert from second into years.\n\n(this matches pretty good using the estimated 2005 eneregry consumption of about 4.6*10^27erg as well)

Four hemes and four globins. 4x10^6 - 10x10^6 in normal adult males.

depending if you are dieting or not, probably between 1500 and 2500 a day.  Men probably more.\n\nSee men always have it better, they can even eat more....lol
