The average adult, when resting, inhales and exhales about 7 or 8 liters of air per minute. That totals about 11,000 liters of air per day. Inhaled air is about 20-percent oxygen. Exhaled air is about 15-percent oxygen.

Food poundage Interestingly, research shows that most humans eat between three to five pounds of food per day. Indeed, as we approach four pounds of food intake for the day, most of us are feeling pretty satisfied. Now, this can be four pounds of celery.

The average person's skin covers an area of 2 square meters. Skin accounts for about 15% of your body weight. The average adult has approximately 21 square feet of skin, which weighs 9 lbs and contains more than 11 miles of blood vessels.

This makes up 0.04 per cent of the permanent gases we breathe in, being converted to about 4.5 per cent of what we exhale. Only 21 per cent of what we inhale is oxygen and of this, 15-18 per cent is exhaled, the body retaining (generally) enough for its needs.

The usual dose for long-term treatment of asthma is 1 inhalation 3 to 4 times per day. The maximum daily dose is 4 puffs per day. For preventing exercise-induced asthma, the usual dose is 1 inhalation 15 minutes before exercise.

Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter).

The more your weigh, the more water you need to drink. For instance, a healthy person, weighing in at 70 kg and measuring 5 feet 10 inches would be required to drink around 2 litres of water each day. Adult men need to drink more water than adult women, but not by much. The difference is roughly around 0.5 litres.

To support the absorption of oxygen and release of carbon dioxide, about 5 to 8 liters (about 1.3 to 2.1 gallons) of air per minute are brought in and out of the lungs, and about three tenths of a liter (about three tenths of a quart) of oxygen is transferred from the alveoli to the blood each minute, even when the ...

We swallow about 2 quarts of air a day just eating and drinking. We burp out about half of that. The rest travels through the small intestine and out the rectum in the form of flatulence. Most of us do not have a problem processing and expelling this gas.

The average adult at rest inhales and exhales something like 7 or 8 liters (about one-fourth of a cubic foot) of air per minute.

One study looked at adults who consumed less than 41 oz (1.2 liters) of water per day. When they increased their water intake to 85 oz (2.5 liters) per day, they were happier, had more energy and felt calmer ( 19 ).

So breathe easy. The average human exhales about 2.3 pounds of carbon dioxide on an average day. (The exact quantity depends on your activity level—a person engaged in vigorous exercise produces up to eight times as much CO2 as his sedentary brethren.)

Normally, humans breathe in air that is approximately 20.95% oxygen, 78.09% nitrogen, 0.93% argon, and 0.04% (400 ppm) of carbon dioxide. Like CO2, oxygen also dissolves in the lungs and is transported to the blood via diffusion across the lung tissue (alveoli).

At the end of each exhalation, the adult human lungs still contain 2,500–3,000 mL of air, their functional residual capacity or FRC. With each breath (inhalation) only as little as about 350 mL of warm, moistened atmospherically is added, and well mixed, with the FRC.

The search engine responded with the claim that a single fart burns approximately 67 calories, and that farting 52 times in one day can burn a whole pound of fat.
