Respiratory System

Breathing brings oxygen, found in the air we live in, into a unique set of organs called the lungs. Deep inside the lungs, that oxygen is transferred into the blood system and is used to power all of our muscles, including the muscles that produce breathing. Dr. Reisman takes you through the structures of the air passageway, the anatomy and physiology of the lungs themselves, and reveals the mechanism of the incredible gas exchange between the respiratory and cardiovascular systems.
