Verified step by step guidance

Understand the role of the trachea in the respiratory system. The trachea, also known as the windpipe, is a tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Consider the options provided: Absorption, Filtration, Diffusion, and Conduction. Each term describes a different physiological process.

Absorption refers to the process of taking in substances, typically nutrients or gases, into cells or tissues. This is not the primary function of the trachea.

Filtration involves the removal of particles or impurities from a fluid. While the respiratory system does filter air, the trachea itself is not primarily responsible for filtration.

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. This process is crucial in gas exchange in the alveoli, not in the trachea.

Conduction is the process of conveying or transmitting something, such as air. The trachea's primary function is to conduct air between the external environment and the lungs, making 'Conduction' the best descriptor.
