hi all,
I learned that heart endothelial cells are directly facing artery blood and supported by non-cell basement membrane.
Thus it makes sense to me that it is more efficient for endothelial cells to take up nutrients from right neighboring blood than from interstitial fluid, because the for the later nutrients need to pass through the extra basement membrane.
Hope hear from you guys, thks a lot.

Dear Jiyuan:
What a interesting question. I really don´t know, but now I will not sleep well!! In my opinion, living systems don't waste energy / mass. Thus, they provably take nutrients from both fluids. But, it is possible that they take some specific nutrients from one side and some other from the other..
I will try to learn about your wonderful question. Thank you!
