In which process do epithelial tissues serve a sensory function?

Epithelial tissues serve a sensory function primarily through the process of sensation. These tissues contain specialized cells that can detect changes in the environment, such as temperature, pressure, and chemical stimuli. For instance, in the skin, epithelial cells are involved in the sensation of touch and pain, while in the taste buds of the tongue, they detect different flavors.

This sensory capability is crucial in allowing organisms to interact with their environment effectively, responding to potential dangers or changes that may require action. Other processes like absorption, secretion, and excretion focus more on the transport of substances and the removal of waste rather than the function of sensing stimuli in the environment. Hence, sensation is the most accurate and relevant process associated with the sensory function of epithelial tissues.
