A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?
a)
The swollen gums have absorbed the saltwater solution.
b)
The saltwater solution lowers the temperature of the water in the gums.
c)
The salt in the solution has moved against the concentration gradient.
