De què tracta
Text molt breu sobre què distingeix el que és viu del que no ho és, i què passa quan deixa de ser-ho.
Context i història
Poques pàgines, i sovint editat com a part de «De la respiració». La seva brevetat al catàleg no és cap defecte de la còpia: l'obra és així. Forma part dels «Parva naturalia», els vuit opuscles breus que continuen la «De anima» aplicant-ne la teoria a fenòmens concrets del cos viu. Es transmeten com un grup i es llegeixen millor seguits.

All the veins pulse, and do so simultaneously with each other, owing to their connexion with the heart. The heart always beats, and hence they also beat continuously and simultaneously with each other and with it. Palpitation, then, is the recoil of the heart against the compression due to cold; and pulsation is the volatilization of the heated fluid. Part 27 Respiration takes place when the hot substance which is the seat of the nutritive principle increases. For it, like the rest of the body, requires nutrition, and more so than the members, for it is through it that they are nourished. But when it increases it necessarily causes the organ to rise. This organ we must to be constructed like the bellows in a smithy, for both heart and lungs conform pretty well to this shape. Such a structure must be double, for the nutritive principle must be situated in the centre of the natural force. Thus on increase of bulk expansion results, which necessarily causes the surrounding parts to rise. Now this can be seen to occur when people respire; they raise their chest because the motive principle of the organ described resident within the chest causes an identical expansion of this organ. When it dilates the outer air must rush in as into a bellows, and, being cold, by its chilling influence reduces by extinction the excess of the fire. But, as the increase of bulk causes the organ to dilate, so diminution causes contraction, and when it collapses the air which entered must pass out again. When it enters the air is cold, but on issuing it is warm owing to its contact with the heat resident in this organ, and this is specially the case in those animals that possess a full-blooded lung. The numerous canal-like ducts in the lung, into which it passes, have each a blood-vessel lying alongside, so that the whole lung is thought to be full of blood.…
