The inner walls of the lungs are covered with cilia, small microscopic hairs that are consistently moving in a wave-like flow upwards toward the throat and mouth.

Endosteum
The roof of the nasal cavity.
The combination of cilia and mucous helps to filter out solid particles from the air.
nasal passage
Water is brought through cilia-lined pores into the hollow cavity of the sponge. As water passes through the pores, the cilia trap oxygen to breathe
Sponges have a cavity lined with specialized cells that absorb the food that enters or is swept in by cilia. Not very complex.
alveolus
cilia
the cilia draws water into the mantle cavity
The trachea is lined with ciliated columnar epithelium, which has hundreds of tiny hairs called cilia.
Endosteum
Your fallopian tubes are lined with tiny hair-like structures called cilia which are constantly swaying back and forth to help guide the egg and push it along to the uterus :)

Animals that have lined abdominal cavities are known as coelomates. The coelom, or body cavity, is used for protecting their internal organs.
