Respiratory System

Join the Amoeba Sisters for a brief tour through the human respiratory system! This video will discuss why the respiratory system is so important and address major structures such as the pharynx, larynx, trachea, bronchi, alveoli, and lungs. Video also mentions a bit about surfactant and the impact blood pH can have on breathing. Video has been dubbed using an artificial voice via https://aloud.area120.google.com to increase accessibility. You can change the audio track language in the Settings menu.
