Like many doctors I know, I found myself being peppered with questions from friends and patients—some genuinely curious, others more finger-wagging—after The New York Times Magazine published a long piece in the spring about the “discovery of a third circulatory system.” Recent experiments had shown that foreign materials such as tattoo ink or chemical tracers could migrate into what the magazine described as “hidden pathways” throughout the body—routes that did not correspond with either of the conventionally accepted networks that Western medicine has mapped and taught for centuries. “The implications of a new circulatory system,” the writer claimed, “are potentially enormous.”
The article was referring to the interstitium, a catchall term for the mostly cell-less, latticed network of proteins and fluids that surrounds our organs and tissues.
