Results of blood gas: PO2 is 65. PCO2 is 32. That's on the T-tube at forty percent oxygen. What is the T-tube?

a t-tube by the way is the most cruel thing u can ever do to a patient its like breathing through a straw. But anyways, it is just a way to take a patient off of a ventilator to see if they are ready to be extubated without having to reintubate them. there are ways to do it with vent settings but some docs are just plain dumb and cruel and prefer that method. the po2 for that percent of o2 s low...

You need to first balance the equation.\n\n2CO + O2 --> 2CO2\n\nUsing this you find the answer to be D.

Okie dokie. First, you balance out the equation. You want to make sure you have the same amount of sodium, phospohorous, and oxygen atoms on each side of the "yield" sign. The outcome could be 12Na+P(little 4)+8O(little 2) Yields 4(Na(little 3)PO(little4)). Then you use your periodic table to tell you how many grams per mole are in Na(little3)PO(little 4). The molar mass is 164 g. You only have 156 g, which means you have 0.95 moles (156/164). Now you know that you have half as many moles of oxygen, therefore you only have 0.475 moles of O2. Now all you have to do is do 0.475 moles of O(;little 2) multiplied by its molar mass, which is 32 grams. This will give you 15.2 grams of O(little 2). Note that for the atomic/molar masses, I rounded the numbers to whole grams. I hope that this helped.

the C6H12O6 represents a molecule of glucose that a cell is metabolizing. Cellular respiration oxidizes (burns) food molecules into carbon dioxide and water.  So, the C's in glucose are eventually converted into carbon dioxide (the 6 CO2).  The O2 is oxygen that a cell gets from its environment.  If you're thinking of this happening in you, the oxygen is absorbed by the bloodstream in your lungs from the air that you breathe. The O2 is used to form the water.

100g O2 x (1 mole O2)/(32g O2) x (22.4 L O2 @ STP)/(1 mole O2 @ STP) x (1/1.5) x (298/273)\n\n= 50.9 L\n\nThe 22.4 L = 1 mole is only true @ STP.  The higher pressure reduces that volume and the higher temperature increases it.

respiration..\n\nco2 is given off, it goes through our blood stream, reabsorbed by the alveoli, switched out with o2 by respiration

I'm going with B on this one.  The pulmonay arteries are taking deoxygenated blood away from the heart to the lungs to pick up O2 and drop off CO2.  This would mean that this blood is as full of CO2 as it can be in the body - at least in healthy people.\n\nC, the pulmonary arteries have just dropped off their CO2, so they don't have much. Not it.\n\nD, I think if the PCO2 were higher here than in the blood, then CO2 would diffuse out of the lungs and into the blood. Not it.\n\nE, The CO2 from the interstitial fluid is always diffusing into the veinous blood.  It's kept at a fairly constant rate, so that's probably not it.\n\nA, this could be the answer.  Honestly I don't know the PCO2 of the atmospheric air, but it would make sense to me that it's lower than what's in the pulmonary arteries because, again, CO2 that you breathed in would diffuse INTO the blood instead of out of it.

Nitrogen and oxygen make up around 99% of the total atm pressure. Carbon dioxide, water and other inert gases make up the other 1%. There is a graph called the Oxygen-Hemoglobin dissociation curve, and temp. carbon dioxide and blood pH can shift this curve to the left or right...increase in CO2 the curve shifts right, decrease it shifts left. So in tissues the CO2 levels are higher so the Red Blood Cells pick up CO2 easily and in the lungs the CO2 levels are lower than in the blood and O2 is picked up, and of course there is the Cl shift that occurs. CO2 is a byproduct of cellular respiration...energy production in the mitochondria...this is a long question to answer, there is more to it but I hope this helps.

Every time you exhale, you breathe out most of the air you breathed in. While the air is in your lungs, oxygen travels from air to blood and CO2 from blood to air, in each case moving naturally to where it is less concentrated.\n\nHow long it takes the average oxygen molecule from being absorbed to being breathed out again as part of a carbon dioxide molecule is a really good question - I have no idea if anyone has even calculated it, but we can try.\n\nMost people pass out if their blood oxygen level drops below about 80% - and most people can hold their breath for maybe 4-5 minutes (the record is almost 9 minutes by Houdini, but that's someone trained and a bit freakish). That implies you use 20% of the oxygen in, say, 5 minutes - so it would take 25 minutes to use it all, if that were physically possible.\n\nBTW, I'm prettty sure it's 8-9 pints of blood. The normal O2 reading in arterial blood is around 10-13 kPa, but I'd have to admit I don't know how to convert that to a mass (or free volume) of oxygen.\n----\nOoh, here you go: arterial blood contains about 20ml of oxygen per 100cc. Your blood volume is about 5 litres, so that would mean your body contains rather less than a litre of oxygen (because not all of your blood is fully oxygenated).

oxygen is removed and replaced by co2

Nitrogen by far. it is approximately 78% of what we are breathing

O2, N2 and CO2.\n\nDon't understand the last part

Without doing a rigorous calculation I will guesstimate that it will be Oxygen.\n\nIf body is 70% water, Oxygen in water is ~90% so oxygen will be ~63% in body.

blood, fluid pumped by the heart that circulates throughout the body via the arteries, veins, and capillaries (see circulatory system; heart). An adult male of average size normally has about 6 quarts (5.6 liters) of blood. The blood carries oxygen and nutrients to the body tissues and removes carbon dioxide and other wastes. The colorless fluid of the blood, or plasma, carries the red and white blood cells, platelets, waste products, and various other cells and substances

Do you mean in relative terms (percent change) or absolute terms (mm Hg)?  In % terms, the pCO2 changes the most.  In absolute terms, the pO2 changes the most.  See my source for a table of the typical numbers.
