Quizplus · Accepted Answer

Ciliary hairs are hair-like structures found in the respiratory tract that help in removing foreign bodies such as smoke and bacteria by trapping them and moving them out of the respiratory system through coughing or swallowing. Villi are finger-like projections found in the small intestine that aid in nutrient absorption. Golgi bodies are involved in protein modification and sorting. Erector pili are muscle fibers that are responsible for causing hair to stand on end, such as during a "goosebumps" reaction.
