Question

Quizplus · Accepted Answer

Cilia are hair-like structures that line the respiratory tract and help to trap and move foreign particles, such as dust and bacteria, away from the lungs. They beat rapidly, moving mucus and trapped particles up and out of the respiratory system, helping to keep the lungs clean. Flagella are similar structures found on certain cells, but they typically move in a wave-like motion to help cells produce movement. Basal bodies are organelles that help in the formation of cilia and flagella, and microvilli are small, finger-like projections found on certain cells that help to increase surface area.
