The DVD BOOK series ‘Spacetime Cube Monade’ totally captures all images unfold in time and space axis through the story with 3D cubic world.

Digestion is how we take life from other things and incorporate it into our own. The large molecules having composed other living things are broken down into smaller, microscopic molecules. Each of the epithelial cells absorbed the molecules of nutrients through a thousand microvilli that make the boundary between the inside of the body and the outside. Now small molecules will be assembled into large ones, creating new life in our human bodies.

Now let’s see details of the digestion process, making full use of microscopy. Why the stomach never digest itself? Why the stomach digests only food? Why does the small intestine need to be so long? In our body, many cells are turning over continuously, and the sloughed-off cells of our own bodies are broken down and digested.

Receipt of taste and odor information triggers selection of nutrients to take into the body. The autonomously acting digestive tract has individual neuron system and net working among cells. There are our immune system and symbiotic bacteria in the human digestive tract. When we look at the digestive tract in this way, we recall evolution of creatures. The digestive tract calling this second brain may be the first home of our mind.
