Galenworked only with dead tissues

Galen
worked only with dead tissues and in these tissues only
the veins were observed to contain blood; he thus
concluded that the veins alone carried the blood of
the circulatory system, while the arteries carried the
life-giving air. Since there was no obvious direct connection
between the two sides of the heart Galen suggested
that the ventricles of the heart were linked by
invisible pores called “septum” whose purpose was to
allow the blood to move freely between the two sides.
