@jvboy88 We are introducing air into the air pathways through a tube in the trachea off camera, in order to demonstrate the filling of the lungs, their innate elasticity, and the manner in which simple lung volume changes effect motion in other organs.
@drumaboy200 The diaphragm in normally related to the costal margin, which has been removed, so the free edge of the diaphragmic tissues have been tucked out of view, since their "action" was not part of the experiment, but rather the manual inflation of the lungs via a tube.
@D000242 You'd be loathe to donate your body then, which is, of course, your prerogative :-) The clip shows the manner in which lung inflation affects related organ mobility as a function not merely of diaphragmatic action, but from the changes in lung volume alone. I have more footage of the motion of the liver as induced by this lung inflation, import to visceral manipulators. We also learned something about the fixation of the lungs relative to pathological adhesions. Every breath is a gift!
@D0000242 PS: We weren't a bunch of "goofy students," but several adult researchers, in awe of the beauty of the human form. I have a Ph.D., we worked with full consent of the institution with a body donated for research, and I take satisfaction in knowing that I fulfilled the donor and donor family's wishes that their gift be both appreciated, used, and learned from, and that so many continue to learn from this gift that keeps on giving with every viewing of this clip.
@fraktel Actually, I do this regularly with fixed specimens as well. In this example the tissue is indeed not fixed or preserved in any way, so the colors are more vibrant than when the material is fixed with a preservative, but it doesn't last very long consequently!! Thank you for watching and for your comments!
@ShaolinIronLeg These are human lungs, and they are being artificially inflated. We used a donor body, and the ribcage has been removed so that you can see the way that the air inflates the lungs. Thank you for watching!
@bridgette1213 Because we were introducing the air from the mouth of the form with a tube, each "artificial breath" sent some air not only into the bronchial tree of the lungs, but also down the esophagus, causing the stomach to receive air in a manner that would be normally excluded in the living.
It has taken mankind 75 years to go from the first electrical binary computation and room size computers to todays nano and atom computers emerging on the horizon.
What are your thoughts if any, on replacing the lungs with a manigable sized instrument.
@DaiTasshiWill Well, these lungs represent millions of years of refined perfection. While I wouldn't put it past human ingenuity in some way to mimic some of their attributes mechanically, I won't hold my breath till it happens :-)
@DaiTasshiWill No artificial device can mimic the level of vascularization and efficiency of gas diffusion between blood and air as the natural lung. Not now anyway.
@abslisa I could be wrong but I think rotting is when bacteria eats you. A healthy immune system would avoid that. The immune system, like any other part, does require certain nutrients. Antioxidants are part of equation to avoid system damage so there's less to repair/replace from free radicals. Circulation also to allow white blood to get where it needs to, and oxygen to give cells the energy they need to do their jobs.
At the upper portion of the frame, between the lungs, the yellow mass is the loose, aereolar fascia which covers the mediastinal structures centrally...it has been pushed up off of the fibrous pericardium enveloping the heart. Lower in the frame, there is a general, thin layer of fatty aereolar fascia remaining over the abdominal musculature. Thanks for watching!
There is no "action" in the diaphragm visible. The ribs have been dissected away to expose the organs, and since the costal margin is the diaphragm's "anchor", it is just laying passively over the abdominal viscera in the lower left portion of the screen, covered with its membranes. The breathing has been generated artificially in this donor form by inflating the lungs through the trachea, bypassing the need for any action from the diaphragm. Thanks for asking, and for watching!
@Koolzii I don't think the diaphragm pushes the lungs up... when it contracts it creates space and a vacuum effect to help fill them... the relaxation I guess allows it to fill up and push the lungs to expel air but... I wonder what actually does that. Does the diaphragm have an antagonist?
All I can figure is the transversus abdominis since it pulls our waist in, perhaps that or abs put pressure on the diaphram causing it to push up onto lungs?
@tyciol is that a question ?, And the Diaphragm helps Lung movement, Pushes air the Lungs up and Down, To help Exhalation and Inhalation. You dont think the Diaphragm helps push the lungs up?, What are you 12?
@Koolzii Please avoid engaging in ad hominem, besides which such ageism is inappropriate, preteens could have superior knowledge of anatomy than either of us. No doubt yours exceeds mine in this manner, which is why I was asking and hoping to learn more from you about how the diaphragm works.
Now that you mention it though, yes. I do not think the diaphragm pushes the lungs up. The diaphragm contracts to create vacuum which helps the lungs fill, it does not push them to empty them out, abs do.
@tyciol Well ok, But What Ive learned from previous lessons of Anatomy is that, The Diaphragm is to help our lungs Move up and down, To help air Move in and out at Steady Intervals. Not alot to it.
@Koolzii The diaphragm does help the lungs move, but you described it as 'pushing lungs up' which is not accurate. When the lungs contract, they push down together, basically just folding in on itself. The vacuum is what brings the air in.
When it relaxes, it doesn't actually return to neutral on its own. It can't exert force to lengthen itself. What happens is the lungs reflexively return to their smaller state as the vacuum force is removed and the abdominal muscles (RA, TA, etc) push it up
and all this sophisticated amazing human body was created by evolution?
I wonder if there is a God the creator as some people are saying out there and many of us still have to discover, like where are we comming from and where are we going, just necessary things before living earth.
That's correct. The fine black/grey lines you see forming the mosaic-like shapes on the surface of the lung are lymphatic pathways with carbon deposition, a normal phenomenon: our air is not perfect, and we filter impurities in this way. Her lungs were quite healthy indeed. Thanks for watching!
Yes, this is normal to find here, and does not represent a health problem. All human hearts have loose aereolar fascia with some measure of adipocyte proliferation, giving the yellow color. In the lower aspect, we are looking at the greater omentum, which is a mobile "apron" of tissue with various interesting properties (it also belongs there and is normal). Thanks for watching!
WOW. that is amazing.
