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.

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.
D. The water in the gums has moved out due to the high concentration of salt in the solution.
The correct answer is:
D. The water in the gums has moved out due to the high concentration of salt in the solution.
When a person rinses their mouth with a saltwater solution, the high concentration of salt outside the swollen gums causes water to move out of the gum tissue through the process of osmosis. This can lead to a decrease in swelling as excess fluid is drawn out of the swollen area.
