The Respiratory System - Unit 11

So we all know that breathing is pretty important, right? Today we're going to talk about how it works, starting with the nameless evolutionary ancestor that we inherited this from, and continuing to the mechanics of both simple diffusion and bulk flow, as well as the physiology of breathing, and finishing with the anatomy of both the conducting zone and the respiratory zone of your respiratory system.

Paul Andersen starts this video with a description of the respiratory surface. He explains how worms, insects, fish and mammals take in oxygen and release carbon dioxide. He then tours the major organs of the respiratory system; from the pharynx to the trachea, bronchus, bronchiole and alveoli. He also explains how oxygen is carried on the hemoglobin and how carbon dioxide is carried as bicarbonate.

Here, I show the actual footage of the procedure being performed.
