    Does anyone know/can explain what/if/how a mammal monitors it's own onboard RBC? Like, I know there is a clotting cascade which occurs during a break in tissue. we lernt that in AP. Mammals body clotting reaction is localized, so all your blood doesn't clot at the same time. There must be some brain center or gland monitoring blood loss/gain. So your heart would be totally aware of the loss of blood during a donation, and a mammal can compensate by vaso-constriction, right?
    I beseach you to explain what pathways contribute to homeostasis r/t blood loss/gain. Why do you get a sick feeling, and why does RBC loss/gain knock out a seemly willing person whose hydrated and normal? I'm sorry. i gots to know :-( [in your debt] :kiss
