A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?

• The swollen gums have absorbed the saltwater solution.
• The saltwater solution lowers the temperature of the water in the gums.
• The salt in the solution has moved against the concentration gradient.
