This gives the atria time to squeeze blood into the ventricles before they fire. The impulse is then carried by way of the AV bundle and the right and left bundle branches to the apex of the heart and then spread through the walls of the ventricles towards the base of the heart.
Microculture is a card-based group game that embodies the behavior of our human microbiome. It is also an icebreaker game that relies on a simple form of social interaction. The idea is to create correlations between the needs of the culture and the actual personal preferences and cultural backgrounds of the players.
It is often essential to isolate a pure culture of microorganisms. A pure (or axenic) culture is a population of cells or multicellular organisms growing in the absence of other species or types. A pure culture may originate from a single cell or single organism, in which case the cells are genetic clones of one another. For the purpose of gelling the microbial culture, the medium of agarose gel (agar) is used.
