The average exchange of air per breath is 500 ml for men and 390 mL for women and the average breathing rate is about 12 times per minute. That's about 6 litres a minute, 0.360 m3/hr for men and 4 litres a minute, 0.240 m3/hr for women.
The average respiratory rate varies by by age:
As a consequence the actual tidal respiration volume for any individual would have to be calculated.
Answer:
A person breathes about 100 litres (0.1 m3) of air every hour.
The Earth's atmosphere is composed of approximately 78% nitrogen. This means that nitrogen makes up the majority of the volume of the air we breathe.
Oxygen is approximately 21% of the air we breathe.
Oxygen is the most abundant element in Earth's crust.
78% of the air we breathe is nitrogen. 21% is oxygen, and the other 1% is a mix of other gasses.
No, the air you exhale is nearly saturated with water vapor. During breathing, air is exposed to the moist tissues of the sinus, trachea, and lungs, and will typically contain substantially more water vapor when exhaled. The only exception would be for air that is already saturated or supersaturated with water.
peak volume is on average 600 liters an hour so 600/60*5= your answer
Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
78.09% Nitrogen by Volume (approx)
The volume of air which you normally breathe in and out is called the tidal volume. This is normally about 500 cm3 when you are at rest. However if you breathe in as much as you can you can breathe in more than 500 cm3. The extra volume of air breathed in (inspiration) is called the inspiratory reserve volume.Similarly when you breathe out as much as you can, the extra volume of air breathed out (expiration) is called the expiratory reserve volume. These three volumes added together give you your vital capacity: the maximum volume of air you can breathe in or out. When you have breathed out as much as you can there is still some air left in your lungs ie you cannot empty your lungs completely. This volume is called the residual volume.The vital capacity plus the residual volume equals your total lung capacity. See http://en.wikipedia.org/wiki/Lung_volumes http://www.healthsystem.virginia.edu/internet/anesthesiology-elective/airway/lungvolumes.cfm
When you breathe in, the volume of the thorax increases. This is due to the contraction of the diaphragm and expansion of the rib cage, creating more space for the lungs to expand and fill with air.

There is enough air inside to last you an hour or two comfortably.
Yes, an octopus can breathe outside of water for a short period of time because they have gills that allow them to extract oxygen from the air.
The amount of air you can inhale above tidal inspiration is called inspiratory reserve volume (IRV). It represents the additional air you can breathe in after a normal inhalation.
They breathe air with lungs.
They do breathe air.
