The cisterna chyli is dilated structure on the thoracic duct that serves as a storage area for lymph moving into the venous system.

is this a trick question because the lymph must go through another area before going into the venous system??

For zombies there comes time of science-fiction.
The year humans embark a great medicine to cure deases and live longer than any decade has ever had. With great modern tech. and brains we can find something never before, stemcell research, reguvenating cells, with biomedical military hardwear. Is it possible for humans one day, to bring dead cells back to life?? Or clone dead cells? What would this mean for us, stem cell research, we were able to clone cells, back in 2006. Would you think a few decades, we would able to bring dead people to life, not literally but cloneing the dead?

And what would be a worst place for zombies to infest? a hospital, morgue? school?

Is there any way that we can mutate cells? or evolve cells with stem cell research, like the scienctists cloning cells.

Will humans be responsible for their own destruction, hydro bomb, global warming, deases ect.

Is there a slight reasonable doubt that one day we would get something close to a living dead?
