The mucus that accumulates in the ET tube is secreted by goblet cells in the bronchial epithelium, and pushed upwards towards the larynx by actively waving hair-like projections on epithelial cells, called celia. This secretion is natural, and is a defense against pathogens and particulate...

Suctioning of the airways is done for all ventilated patients. It removes the mucus build up from the endotracheal tube, but it doesn't remove any fluid from the lungs.

There are several reasons: - the exudate collects in alveoli and bronchioli, which are extremely small structures. Getting a suction tube into an alveolus would be practically impossible - even if you managed that, there are hundreds of thousands of alveoli to suction - if you simply try to...

As far as I know, objects don't "orbit" Lagrange points. They orbit the Sun, at the Lagrange points. Lagrange point asteroids don't orbit the Lagrange points - they oscillate in their orbits around the Sun as they are pertubed by the other planets, and due to the slight elliptical nature of...

That's incorrect. Objects at a Lagrange point orbit the larger body - in this case, the Sun. They remain in the same orbit as the smaller body (in this case, Jupiter), orbiting the larger body with the same periodicity as the smaller one does.

True. But the combined object still doesn't stand still (ie. "stop"). This was the premise of the OP, who assumes that an asteroid actually stops at the Lagrange points and gets pulled/pushed along by Jupiter. It doesn't. If it did, it will crash into Jupiter and burn up. The asteroids at...

I would like to see your reasoning behind that, because you seem to be laboring under some misconception (assuming your term "coming from somewhere" means "originating in the asteroid belt"). Any asteroid crossing Jupiter's orbit while on a highly elliptical orbit won't be "captured" in...

Majority of them start their life in the asteroid belt, between Mars and Jupiter. They don't stay there their whole life. The asteroids at the outer edge are pertubed by Jupiter, and those on the inner edge are pertubed by Mars. There are also collisions among the asteroids. These pertubations...

Please see my post (#8 in this thread). The definition of "caught" that you are using is wrong when applied to Lagrange asteroids. Therein lies the problem. The asteroids don't get caught into Lagrange points. They get slowly nudged and herded into those positions over hundreds of orbits. This...

Let me attempt a round on this merry-go-round. There were 2 comments on this thread by the OP that caught my attention. One was: OK, then how can we still see the light from those two stars on the same scale we see the separation between them? The other was something about the stars having to...

The asteroids at the Lagrange points don't "stop", nor do they orbit Jupiter. Those asteroids orbit the sun, and do so with the same periodicity as Jupiter. The trojan asteroids aren't actually "captured" (as in, they are flying somewhere, happen to cross the Lagrange point and suddenly turn...
