We know the nerves transmit the experience of your body organs to the brain that makes sense of sensation, as well as to densely woven nets of nerves that respond reflexively.
The nerves carry sense, but perhaps other organs do so too.
The heart pumps blood through the arteries and capillaries to irrigate everything, out to the extremities of the body. Billions of cells constantly go out and have encounters, and then return to the heart.
A blood cell is a living thing in a complex world. It has grown out of eons of experience to be ready for this particular world, and when the world changes, it will have to adapt.
So the heart and its rivers of blood, like the brain and its networks of nerves, both send out impulses and receive intelligence. They are ways of building awareness out of the feelings of a body in a world.
Likewise the lungs inhale and expel the atmosphere, the moving body explores space, the eyes and the ears scan the distance, and the epigenes tweak the software. Every part has a part to play in building Worldly Awareness.
Plants and Animals and Microbes have all these ways of touching and sensing the world: networks, flows, biomes, mutualism, symbiosis, predation, bonding, immersion.
Blood learns. Awareness grows.
