ventilation perfusion coupling?
595984
I'm not certain what you're asking, so I'll just dump out the information that may be relevant.\n\nVentilation is the process of getting usable oxygen into the lungs.  Perfusion is the process of circulating blood to the lungs to pick up the oxygen.  When your patient has the oxygen mask on, you are increasing the ventilation by increasing the concentration of oxygen entering the lungs.  This, in turn, will not increase the perfusion since it has no effect on the blood vessels, but will increase the efficiency of perfusion because of the increased oxygen gradient.

It works with each heartbeat.  The gas moves with each heart beat. The area of the lung where the blood takes the gas is called the A/C membrane (Alveolar/Capillary) the membrane is so thin so the gas can diffuse into the blood.

Mm...I remember when I did this lab last year. I will try to help you \n\n1. I don't remember. If you add more details...I'll be able to help you\n2. We need an equilibration period, so we start the experiment in all the vials at the same condition. SO..all of them are at the same temperature, pressure and we won't get far away from the expected results.\n\n3. the volume? Well...I am not sure about this one. You should explain a little bit more. But..I remember that KOH that you  you put in the cotton will absorbe CO2 produced by the vials that have the respiration process going on.\n\n4. again..provide background information about the experiment\n\nPLEASE...we know that it is about cellular respiration. But it the questions don't make sense to us if we don't know a little more about the procedure!

You can use a spirometer to do it. Please check out this link I am giving you, it will solve your problem. They have really done it well\nhttp://intranet1.sutcol.ac.uk:888/NEC/MATERIAL/PDFS/HUM_BIO/AS_HUMAN/23U2_T2.PDF\n(We can measure the volume of air moved by the lungs using a. spirometer .

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.

Only using 25% in normal circumstances allows increased uptake from the same blood flow if required.  This further removal from the haemoglobin being easily achieved with little drop in PO2 as it is on the steep  part of the dissociation curve.  "An exercising muscle can extract virtually all the oxygen from its blood supply."\nAlso agree with above answer that otherwise, if you missed a single breath, blood with no oxygen would enter the arteries.

well theres one for pulse and one for oxygen saturation.  check also with respiratory tech infor

called a rebreather and it circulates your air and scrubbs it clean so you have air to breathe , closed loop system. its a large backpack thing and it requires special training. james bond thing is cool but non existent.

Not really an issue of the lungs getting enough oxygen or glucose.  If the heart is failing, blood starts to get backed up in the lungs.  The result is called "pulmonary edema."  Fluid seeps out of the pulmonary capillaries into the alveoli.  This makes it hard to breathe (it interferes with gas exchange).

First i would like to know, what do you mean by "TRACING"? do you mean the measurement of blood flow?\n\nSecondly i really dont know how you can connect right atrium and aorta ?\n\nIf it is left ventricle and aorta you can measure by dopper the flow and cavity size of the chamber

Ventilation - the physical act of moving air in and out of the lungs.\n\na)  Passage way resistent would reduce the volume of air that could be inspired - either by hyperinflating the lungs thereby not allowing new air to fill the lungs with breathing OR by the simple resistence itself, no allowing air in (but its usually the former).\n\nb) Decrease lung compliance would reduce the inspiratory volume and therefore decrease ventilation.\n\nc)  If the lungs did not secrete surfactant, the surface tension of alveoli would be much higher and it would not be able to inflate normally.  Therefore ventilation would be reduced again.\n\nSo after I help you with your homework, are you going to buy me lunch?
