An example of filtration in the body is the movement of water and small solutes through the walls of capillaries.

This is true. Filtration is a process in which substances are separated based on size or charge by passing through a filter. In the body, filtration occurs in the kidneys, where blood is filtered to remove waste products and excess water. In the capillaries, water and small solutes such as ions and nutrients can pass through the walls of the capillaries through a process called filtration.
