Oxygen Intake Stems

In the Aímavascular and mechano-respiratory system, Oxygen Intake Stems are an external mechano-organ which (as described in the Magentic Lungs article) are designed to vacuum in any Oxygen in the air and feed it directly down in to the lung it is dedicated to.

Appearance
As depicted in images illustrated in the book of Animalia-vita, oxygen intake stems are meant to take multiple forms, the first part of the illustration depicts the stem to appear much like a metallic horse-leg, much like that of the Xenomorph dorsal tubes as seen in the movie "Alien".

The second image depicts the stem to appear as a form of branching tube corals and the third image depicts it's appearance as being similar to that of a set of grape stalks.

Purpose
The primary purpose of these peculiar stems is to "inhale" quantities of Oxygen constantly without the need for oral inhilation (in the case that suffocation may occur during metal consumption).
