This video explains how the structure of the #lungs enables #inspiration (breathing in) and expiration (breathing out). I begin by explaining the concept of #pressure and how pressure differences cause air to flow. Then you will learn about how this is harnessed by the body through altering the size of the thoracic (chest) cavity. The size of the chest cavity can be altered through the action of the two main respiratory muscles; the intercostal muscles, and the diaphragm. • [00:00] Start • [00:15] Air Pressure • [04:42] Inspiration • [07:53] Expiration • [10:33] Expiration during exercise • _____________ • Become a Patron!
