Ciliated Cells & Their Adaptations

Six vocabulary flashcards covering ciliated cells, their locations, structures, and key adaptations.

Ciliated Epithelial Cells

Specialized cells lining passages such as the trachea and oviduct; their surface is covered with microscopic hair-like structures called cilia that beat rhythmically to move substances.

Trachea

The windpipe; a tube leading from the larynx to the bronchi where ciliated cells move mucus, dust, and germs away from the lungs.

Oviduct (Fallopian Tube)

A female reproductive tube in which ciliated cells help transport the egg from the ovary toward the uterus.

Cilia

Tiny, hair-like projections on the surface of certain cells that beat in coordinated waves to propel fluids or particles.

Mucus Sweeping

The process by which ciliated cells in the respiratory tract move mucus laden with dust and pathogens out of the airways.

High Mitochondrial Density

An adaptation of ciliated cells; numerous mitochondria supply the energy (ATP) required for continuous ciliary movement.
