I am test the lung capacity of 7th graders and along with my project I need a report. I have found some information on lungs in general, but I still need information on lung capacity.

You might take a look at information on peak flow as well which is a common test for the "quality" of your lungs with Asthma ( I am 25% down) \n\nTables exist for testing in the workplace for lung capacity\n\nhttp://www.biologycorner.com/worksheets/lungcapacity.html\n\nthis rocks for kids! ...careful with over inflated balloons they are high pressure if the mouth is used as a one way valve on inflation then opened!\n\nhttp://www.biologycorner.com/resources/BSA_formula.gif\n\nmight be all you need\n\nLONG TEXT FROM: \nhttp://emphysemafoundation.org/featurearticles.jsp\n\n Measuring Lung Capacity\n\nA simple device called a spirometer measures your lung capacity.  During this test you take a deep breath, as deeply as you can, and blow it out all at once into a machine that records airflow and capacity.  The total amount of air blown out of fully inflated lungs is called the vital capacity.  Since the air is forced out by your muscular effort, it is called forced vital capacity (FVC, newer term FEV6).  This test measures the useful size of your lungs.  The rate of airflow tells how open the air passages are and how well the lungs can empty, or how well their elasticity is functioning.  The lungs empty somewhat like an inflated balloon.  Remember how a flabby or overused balloon empties slowly and incompletely?  This is a lot like the lung with emphysema.  The airflow test is called the forced expiratory volume in one second, since this airflow is timed or measured over the first second of exhalation.  The symbol for forced expiratory volume in one second is FEV1.  These two tests, the FVC and FEV1, reveal all your doctor needs to know about your lung capacity and airflow.  These two numbers are somewhat similar to systolic and diastolic numbers in blood pressure readings.  We believe that knowledge of FVC and FEV1 is as valuable and important to health promotion as knowledge of blood pressure.  These tests measure your lung power, which is essential to your continuation and enjoyment of life.\n\nNormal values are based on age, sex, and height.  Younger and taller individuals have greater airflow and air volume than shorter or older people.  Men have slightly greater airflow and air volume compared with women of the same age and height.\n\nSelf-Testing-   Try It Yourself\n\nNormal lungs have large volume, and they empty quickly because airways are open and lungs are elastic.  You can do a little checking yourself with a stopwatch.  Take a full breath; hold if for one second.  Then, with your mouth open, blow out as hard and fast as you can.  Your lungs should be completely emptied – meaning that you can blow no more air out even though you try--  in no more than 4 to 6 seconds. \n\nIf one takes longer to blow out all the air, it means that airflow is obstructed or limited.  Today we use the term “limited” because this airflow reduction can be due to either a loss of lung elasticity (emphysema) or problems with airways (asthmatic or chronic bronchitis).  See how simple it is!\n\nUnfortunately, routine lung function tests have been accepted all too slowly.  No person would go for a complete check-up if the physician did not examine the eyes, ears, nose, throat, listen to the heart and lungs, feel the abdomen for any abnormal masses, and examine the genital, rectal, and pelvic areas.  All these are routine, and to supplement them, appropriate laboratory blood and urine tests are done, plus an electrocardiogram and, usually, a chest x-ray.  Unfortunately, none of these examinations or tests identifies early COPD.\n\nOnly spirometric measurements of the kind we have just described can identify the patient who is just beginning to develop a lung abnormality.\n\nWhen one considers that the disease process finally resulting in disability may go on for 20 to 30 years, doesn’t it make sense to identify the problem early and to take immediate corrective action?  The answer must be yes if you are to a enjoy a long happy life

If this is for your GCSE next week I think it's high time you got hold of a textbook and read through the section on cellular respiration as if your very life depended on it, and started regretting all the messing about you did in class when you should have at least been making some bare essential notes on this stuff. Perhaps see if your local library opens sundays if you already lost / burnt your school textbook.\n\nTo be more helpful, in brief:\n\nBreathing DOES NOT = "respiration". That's an old, outdated and confusing term for it that no-one should use any more (we now use "ventilation") .... yeah, i recognise this as something i had on my own GCSE years ago by the way :-)\n\nActual respiration is the act of metabolism, and in a vague sense, "living life" by the cell itself - the using up of raw materials ("food" e.g. glucose, and oxygen) to produce usable or storable energy (e.g. for movement, carrying out chemical reactions) and releasing less energetic waste materials (carbon dioxide, water).\n\nAerobic respiration releases a large amount of energy for each unit (eg molecule) of glucose supplied, as it uses oxygen (for what, don't worry for now, as that's degree-level stuff i still can't properly grasp... it accepts electrons, there you go :-) and allows the byproducts of early glycolysis to undergo conversion to pyruvate and enter the krebs cycle. You get... what was it... 18 molecules of energy-storing ATP out of each glucose molecule when it's involved this way.\n\nAnaerobic respiration is a more basic, primitive form of getting energy from glucose (or similar molecules), where the reaction is pretty much that you take the glucose and split it into two fructose molecules, gaining 2 ATP in the process. That's it. No oxygen required, but some less friendly waste materials e.g. lactic acid are produced. This is mainly used in bacteria, which tend to find themselves in food-rich environments, have very little energy requirement for vigourous life, and few worries about buildup of waste materials .... it is also the reason you die if suffocated, and get pains in your legs if you overexert yourself - the body cells can't make enough energy from their limited glucose supplies to survive without using the krebs cycle, and the mass build up of lactic acid in oxygen-starved muscles is very damaging.\n\nThere you go hows that for a textbook answer. That'll be a bag of fizzy cola bottles please. Mmmmmm.\n(That all came off the top of my head, but ONLY because i've been through that particular bloody mill four times so far - GCSE, A-Level, Biology degree and clinical training)\n\ngood luck

For more information and to alleviate your curiousity, I suggest you go to the Library of Congress' website at:   loc.gov and post your questions there. As this is the largest library in the world you will receive more information than you asked for originally. For any school question this site is probably your best bet for great answers.

Just curious why a teacher wouldnt ask the school admin about this first, but since you asked - it is very possible to get it done. Most likely the duct work in the school could use a good cleaning (dust buildup, mouse poop, whatever).  BUT it would also be a good idea for actual air quality testing to be done by the environmental health agency near you, because if you are having these reactions, I bet the students are too.

Vital capacity is the total amount of air that we can exhale forcefully. To calculate vital capacity, first you add your tidal volume and the extra amount of air beyond the tidal volume that your lungs can hold (the IRV). So, so far:\n\nVC = TV + IRV\n\nWhen you take the deepest breath you can and then exhale, you exhale first your IRV, and then your TV, but then you have even more air in your lungs that you can exhale if you need to. This is called the ERV. When you are measuring how much your lungs can exhale when they are FORCED to, ERV is part of the equation. So now:\n\nVC = TV + IRV + ERV\n\nThe reason you include ERV is because normally you don't exhale that amount of air (normally you will only exhale your tidal volume and, if you take a slight deep breath, some of your IRV). However, if you attempt to completely get all the air out of your lungs, you will also exhale your ERV. Since the definition, in general, of vital capacity is the total amount of air you can forcefully exhale, ERV must be a part of the equation.\n\nSide note: what is NEVER a part of the equation is residual capacity, RC. This is the amount of air in the lungs that you can't force out, no matter how hard you try. It is about 1 L.

Alot of bad side effects. Quit now and your lungs will start to repair themselves.  I hate I missed your earlier question, but 16 drops = 1 cc/ml.,  5ml = 1tsp,             15 ml = 1 TBS... Nurse Stay RN, BSN

Do I understand that your teacher wants YOU to give a seminar on health maintenance on 4/2/06? If so, try your textbooks first. That's usually the most accessible source of information. Next, check with the library on books about health maintenance. You can also use internet for information but be careful about using credible, trustworthy sites. This will actually be better than asking someone to just give you the info. When I was in college, we had to cite our sources. I don't think it would go over very well if you had to cite Yahoo Answers for your source.

Everything I know? Oh man, that would take hours no way. I've had it all my life too though, many visits to ER and hospital. Ambulences, nebulizers, peak flow meter, inhaler, oxygen tank. Yup I am an asthmatic all right. Why don't you try a google search under teens + asthma, or adults + asthma, or whatever. It comes up with a lot of info. If you have a SPECIFIC question, I'd be happy to help you with it.

I'd check out the Billy Nye the science guy website... see if you can get a good answer there.\n\nAnd I'd tell your child that they need to start on their reports a little sooner than the day before next time... but you probably already know that...

Let me guess, you forgot to do your homework? If you can come in here and ask us, you can do what we would do to get a best answer and search it in google or something and then stitch a report together from different sites.

If you are really interested in this topic, I recommend reading "The Plutonium Files," a recently published book. It reports on the negative health effects of uranium and plutonium, specifically the results of secret tests performed on civilian citizens and members of the military, by our government. (Almost all of whom were unaware they had unwittingly become guinea pigs.) Very interesting and informative.

Birds air sacs allow them to have a larger "lung" capacity, therefor if humans had air sacs we would be able to run the mile in a shorter time b/c our bodies would theoretically be able to take in more oxygen.

If you have access to academic databases through a university, there should be lots of info in medical journals.  I'd also recommend referring to your local running club and contacting their leadership; if they can't find the exact info you want, they'll know someone who can.
