A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. What has occurred? Options: 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., The water in the gums has moved out due to the high concentration of salt in the solution.
