This activity will take your breath away!
Respiration is a process in a living organism that involves the exchange of Oxygen and Carbon Dioxide. When humans breathe oxygen is inhaled into the lungs and then absorbed into the blood stream. Carbon dioxide of course flows in the opposite direction and is exhaled. Over the course of day this continuous cycle is carried out 19,000 times. But what happens when we interrupt the cycle by holding our breath?
Our test subject in the video explores what happens to his lung’s CO2 levels when holding his breath for varying times.
