Student’s question (10): “I don’t know how to describe the pathway air flows through the body in the Respiratory System”

This post is a response to a student’s question about the pathway of air through the respiratory system.

When we take in a breath, air flows in through the mouth or the nose then it goes through the pharynx ( throat). From the pharynx, it passes through the larynx which is the voice box and then down through the trachea.

The trachea then divides into two primary bronchi through which air passes. These primary bronchi further divide into secondary and tertiary bronchi ( smaller branches). This then divides into the terminal bronchioles which lead to the alveoli. The alveoli is where gas exchange occurs.

If this is difficult to remember, here is a mnemonic that outlines all the passages that air has to pass through before it gets to the alveoli. Click below:
