digestion chamber

Digestion chambers are a histologic finding in nerves that are undergoing Wallerian degeneration.

Digestion chambers consist of small globular fragments, which represent degenerating myelin sheaths.

The two chambers are otherwise unconnected, with sewage flowing only through the upper sedimentation chamber and no flow of sewage in the lower digestion chamber.

In the new scenario, the vaccine bacteria are taken up by the scavenger cells of the human immune system (macrophages) and end up in their digestion chambers, called phagosomes.

Evidence of this behavior had been postulated ever since Charles Darwin's time and has mostly relied on circumstantial findings of the occasional dead aquatic invertebrate in the utricle (digestion chamber).

In an Imhoff tank, fresh sludge is passed through a slot to the lower story or digestion chamber where it is decomposed by anaerobic bacteria, resulting in liquefaction and reduced volume of the sludge.
