What else can I help you with?
What is the average amount of oxygen we breathe in?
About 20%% of the air we breath is oxygen. The PaO2 (oxygen breathed in mmhg) is approximately 100 mmhg.
What is the effect of emphysema on inspiratory reserve volume?
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.

What is weant by qualitative observations and quantitative observations?
quantitative observations can be expressed in numerical terms while quantitative observations are based on your senses - what you can see, hear, smell, etc.
How do you know if a person drowned or died before drowning?
If a person drowned, their lungs would be full of water because they breathed in the water. But if they died before drowning then their lungs would not be full of water as they wouldn't have breathed it in because they are dead.
How are observations made?
observations r made with the five senses (feel, taste, hear, sight, and smell).
What percentage of the air breathed is nitrogen?
78% of air breathed is nitrogen
Why breathed-out air turns time water cloudy quicker than breathed-in air?
breathed out air turns lime water cloudy than breathed out air cuz the carbon dioxide content present in breathed out air(0.04% approximately) as compared to breathed out air(4% approximately)so as CO2 passes through lime water it turns lime water cloudy:)
Which gas is present in air breathed out but is only a tiny part of air breathed in?
because its nice
What can be considered an extreme form of rebreathing?
An extreme form of rebreathing can occur when an individual uses a poorly designed or malfunctioning mask or apparatus that restricts the flow of fresh air into the breathing space. This can lead to a buildup of carbon dioxide in the air being rebreathed, potentially causing suffocation or carbon dioxide poisoning.
What is breathed out?
Air is breathed out of the lungs in the form of carbon dioxide. Air that is inhaled is called oxygen.
Would you use a breathing or non-rebreathing system on a rabbit?
This depends on the size of the dog. A toy size dog would do better with a non-rebreathing system, as it won't have the tidal volume necessary to maintain a good flow of fresh air. A larger dog (say, 15 pounds and up) would be fine with a rebreathing system.
The largest amount of air that can be breathed in and out in one breath is called?
Vital Capacity is the largest volume of air that can be breathed in and out in one breath.
Where does the waste in the air air you breathe out come from?
Much of this air is the mixture that you breathed in but it is higher in carbon dioxide. This gas is produced by your cells as they used the oxygen that you breathed in to make energy.
When you breath in air where is the air going?
It goes down the trachea, through the bronichi and bronchioles, and into the alveoli. There, some of the oxygen in the air that you breathed in is accepted by red blood cells. The rest is breathed out.
How fast is air breathed into the lungs?
It gets pumped.
Where in your lungs will there be a net increase of oxygen?
The air breathed out
Where in your lungs will there be net increase of oxygen?
The air breathed out
