we need about 20 percent a day
Normal air contains approximately 20% O2 and 0.5% CO2. When a human inhales, we absorb and use some of the oxygen we breathe in. Our metabolism converts that Oxygen to Carbon Dioxide, which we exhale, or outgas. However, the process isn't perfect: we don't use all the oxygen we inhale, nor to we exhale all the carbon dioxide in our system. So, when we exhale, the exhaled breath contains either 14% or 16% oxygen, down from the 20% the air contains. This is, by the way, why CPR and rescue breathing work. While your exhalent does not contain the full 20% O2 we see in free air, it contains enough oxygen for a person to survive on.
The actual quantity depends on the size of the person.
Depends on the person and their age, fitness level and whether they are at rest or active. Wikipedia suggests the following:
* Newborns: Average 44 breaths per minute * Infants: 20-40 breaths per minute * Preschool children: 20-30 breaths per minute * Older children: 16-25 breaths per minute * Adults: 12-20 breaths per minute * Adults during strenuous exercise 35-45 breaths per minute * Athletes' peak 60-70 breaths per minute However a person in meditation may go down to 4 breaths a minute and a smker running for his life may be panting very quickly.
In an average gasp of air, only 15-20% is oxygen. When you exhale you release around 10%. In short, 10% would be the ideal minimum.
if oxegyen was water then about 5 gallons of water you breath in each breath
15000mL of air per hour
About 15 gallons
20%
Litterng can cause human sickness because the litter pollutes the air making the oxygen we breath in dirty. This can effect our lungs and the more pollution we breath in, the more gunky build up gathers in our lungs making it hard to breath. This is most likely the cause for asthma and other lung related conditions.
The alveolus is a air sac that holds the oxygen. It squashes the oxygen molecules so they diffuse from the alveolus into the capillary. From there, they attach themselves to deoxygenated Red Blood Cells. The oxygen in the blood plasma are also squashed and are diffused. They go from the capillary to the alveoli to get breathed out. The alveoli transfers the oxygen to the lung capillaries and oxygenates the blood, then it is breathed out as Carbon Dioxide.
No equation is possible, lung volume is measured by a machine in to which you breath.
hey
the capillary's, they are based on the alveoli and they pass oxygen from the alveoli sacks through to the blood stream- ready to go to the heart and be pumped around the body
star fish using lung to breath
The mouse lung and the human lung operate in the same way and they help you breath xo hope this helps ?????!!!!!!
collects oxygen
The lung function of a rat is to take in oxygen you breath and take it to the blood. Then it releases the carbon dioxide from your body.
Tidal capacity is the amount of oxygen the lungs can breathe in and out per breath

Tidal volume is the amount of swag in the air and the amount of banter in a toilet
Lung cancer affects human life because it stops you from doing any kind of sports, (your lungs cant handle the amount of oxygen going through them at one time) you have rapid breathing, sometimes you are left without any breath for a short period of time!
Without the lungs, you're wasting your breath. They introduce the inhaled oxygen to your circulatory system.
fish do not have lung like us. Their gills are designed to extract oxygen from water, and not from air.
They can -- they have gills and have a diffferent lung system they breath in the oxygen from water and need the nutrients in water to survive.
