Do you happen to know how capillary constriction transmits across other organs? Would it be fair to assume that if the capillaries in our skin constrict, capillaries in other parts of the body are constructing too? E.g. I recently read a summary (layperson here) of a paper suggesting Covid 19 triggers capillary constriction in the brain and am wondering if that triggers manifestations in other organs? Or if the circulatory system is big enough that capillaries in one part of the body don’t have to experience the same fluctuations as another (provided no mechanical separation like a tourniquet or tumour or whatever)?
