Drinking alcohol can cause dehydration, which makes the blood hypertonic. Which option best describes the consequences of this hypertonic blood?
a. Hypertonic blood forces water into the interstitial fluid, which makes the interstitial fluid hypotonic. This, in turn, makes the interstitial fluid lose water to the cells b. Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonio. This, in turn, draws water out of the cells. c. Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypotonio. This, in turn, makes the interstitial fluid lose water to the colls. d. Hypertonic blood will lose water to the interstitial fluid, which makes the interstitial luid hypertonic. This, in turn, causes water to move into the cells
