2) The inside of your blood vessels are separated from the interstitial space by membranes that are semi-permeable to water. Just after a salty meal, the osmolarity of your blood plasma increases as solutes are absorbed from the GI tract. What will happen to blood hydrostatic pressure during this time?

3) An ion flows through a channel, down its concentration gradient. Does the cell need to expend energy in this case?
