The Effects of Exercise on Ventilation

The video tutorial explains the structure and function of the respiratory system, focusing on how respiration changes during physical exercise. It highlights the role of cartilage in keeping airways open and the regulation of bronchioles. The tutorial discusses how exercise increases oxygen demand and carbon dioxide production, leading to changes in breathing rate and depth. It also covers bronchodilation mechanisms, including the role of the sympathetic nerve and epinephrine, and the use of bronchodilators like EpiPens.
