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.

In biology, a subculture is a new cell or microbiological culture made by transferring some or all cells from a previous culture to fresh growth medium.This action is called subculturing or passaging the cells. Subculture is used to prolong the life and/or expand the number of cells or microorganisms in the culture.any cell types, in particular many microorganisms, grow in solution and not attached to a surface. These cell types can be subcultured by simply taking a small volume of the parent culture and diluting it in fresh growth medium.
